What makes electricians’ screwdrivers different?
While screwdrivers are one of the most common tools in industries from construction to mechanics and beyond, there is something different about the variety electricians use.
In this article, we’ll talk about what makes electricians’ screwdrivers different, touching on what to look out for when you’re shopping for new tools for your electrical business.
Types of screwdrivers electricians use
Electricians use a range of different screwdriver types. Their choice will depend on the type of fastener they’re working with along with the nature of the job—for example, if they’re working in hard-to-reach spaces, a longer tool will be necessary.
Some of the most common screwdriver types electricians use include:
- Slotted screwdrivers
- Phillips-head or crosshead screwdrivers
- Torx screwdrivers
Slotted screwdrivers, otherwise known as flathead or flat-blade screwdrivers, feature a flat tip at the end of the shaft. These tools match fasteners featuring a single horizontal slot and are one of the most common screwdriver types.
The second most common variety is the Phillips head. These screwdrivers have a cross-shaped head that slots perfectly into matching fasteners, offering a tighter fit and more torque than standard flathead screwdrivers.
Sometimes electricians use Torx screwdrivers, which have a six-pointed, star-shaped tip. You’ll typically find Torx screws on consumer electronics and computer systems, which is why they’re an important part of an electrician’s arsenal.
Insulated screwdrivers: what they are and why they matter
So, while electricians use the same types of screwdrivers as workers in other industries, there is one distinct difference—electricians’ screwdrivers are typically insulated.
Insulated screwdrivers protect the user (and the electrical equipment itself) from electrical injury, damage, and even death. These tools feature a special non-conductive plastic coating around the handle and along the shaft.
This non-conductive material prevents the user from contacting live circuits while performing electrical work. It can also keep delicate parts safe in the event of an electrical short.
The easiest way to ensure your screwdrivers are properly insulated is to look for a “VDE Approved” rating. This approval ensures the tool has been tested for safety up to 1,000 volts, which is the minimum rating for insulated tools and equipment.
Other features of electricians’ screwdrivers
Along with insulation, some electricians’ screwdrivers include other features that can make life easier for tradies.
One such feature is a magnetized tip. Magnetization makes it easier for electricians to line up the screwdriver with the fastener head while reducing the risk of screws falling.
You’ll also find electricians’ screwdrivers that feature ratcheting mechanisms, which allow the user to tighten or loosen a fastener without needing to constantly remove and replace the screwdriver tip.
Where to find screwdrivers for your electrical business
Finding insulated screwdrivers designed specifically for electricians is easy—just look for ‘VDE Approved’ tools or dedicated electricians’ tool kits. These tool kits typically come with a range of equipment electricians need for a standard job, such as screwdrivers, pliers, cutters, and voltage testers.
To sum up
The main feature that sets electricians’ screwdrivers apart from other varieties is their insulation requirements. All screwdrivers electricians use must meet stringent regulations to ensure they are safe to use on and around electrical circuits.

Impacts of Using Blue Light Computer Glasses
The use of blue-light computer glasses can affect your eyes. Some of the effects include eye strain and macular degeneration. You may be able to get prescription eyewear that is specifically designed to block blue light from your computer.
If you are one of the 80 percent of Americans who spend more than two hours in front of a digital device, you are at risk for digital eye strain. There are several ways to minimize the effects of digital eyestrain, from adjusting the screen height to lubricating your eyes with a good eye drop.
The most obvious solution is to take frequent breaks. Taking a break from the screen is not only good for your eyes but also reduces your stress.
Choosing a pair of blue light computer glasses with blue light filtering technology may be a good idea. Blue light harms your eyes and can interfere with your circadian rhythm, which is essential for your health.
However, using a pair of glasses to block out blue light is no guarantee that you’ll get better vision. You should consult your optometrist to determine if your eyes are damaged.
One way to make digital eye strain more bearable is to use night mode settings on your computer. You can also adjust the font size on your screen.
It’s not a coincidence that digital eye strain goes hand in hand with eye fatigue and dryness. These conditions can cause headaches and neck and shoulder pain and interfere with sleep.
If you are looking for ways to protect your eyes from the harmful effects of blue light, you may be interested in purchasing special glasses. These can help you reduce the symptoms of macular degeneration. The right glasses can also prevent you from being blinded by high-energy visible rays from your computer, television, and other electronics.
While there is no cure for macular degeneration, it can be avoided with proper therapy. For instance, taking lutein supplements can reduce your risk of developing the condition. Lutein helps protect the retina from harmful blue light.
Another way to block blue light is to wear sunglasses. Look for glasses with a transmission curve of or less than 0% between 400 and 500 nm. Consider gray or brown-tinted sunglasses for added protection.
Another way to avoid the harmful effects of blue light is to rest your eyes every 20 minutes. It is a challenging task. However, limiting exposure to dangerous wavelengths is possible using a particular film or a lens that filters out the blue light.
Finally, there are magnification glasses that can make things easier to see. Ocular surface cells
Blue light is the most damaging wavelength to the ocular surface. Excessive exposure to this wavelength can increase oxidative stress, one of the main factors leading to eye diseases. Various methods have been developed to reduce blue light damage.
Blue light damage affects the ocular surface through oxidative stress, inflammation, and apoptosis. The ocular surface is the first barrier against irradiant energy.
Blue light has been shown to increase oxidative stress, which is responsible for inflammatory cytokines. It also increases the expression of inflammatory factors in the cornea. It can lead to the development of dry eye disease, macular degeneration, cataracts, and even cancer.
Several animal studies have shown that short-term and long-term exposure to blue light can be harmful. Similarly, a human study showed evidence of oxidative stress and apoptosis in retinal layers.
Research on how blue light damages the ocular surface has led to advances in our understanding of the process. Some fundamental mechanisms are oxidative stress, apoptosis, and mitochondrial dysfunction.
Can you get prescription blue light-blocking glasses?
Blue light-blocking glasses are designed to block out the blue light from electronic devices. These glasses can help relieve stress and headaches caused by long hours of screen time.
Some of these glasses also offer anti-reflective coatings to prevent scratches and glare. They may come in reading or bifocal styles.
The most important measurement to consider when purchasing these glasses is the size and width of your face. If you are shopping online, you should be able to try on the glasses before making your final purchase. You should also be able to return them if you are unsatisfied with the color or style.
Before you make any medical or health decisions, you should consult a doctor. Many people with vision insurance can cover some of the costs, but you should discuss any changes you want to make with your physician.
Most of these glasses cost less than $20, though you may have to pay a few more for some pairs. The more expensive glasses may provide better protection.
Some models are available as non-prescription blue light glasses. It is an excellent option if you want a less expensive alternative.
5 Reasons Most Homeowners Are Installing Solar Panels
Whether you’re looking to save money on your energy bills or simply want to do your part for the environment, installing solar panels is a great way to reduce your carbon footprint. Luckily, there are plenty of reasons most homeowners are installing solar panels on their properties, from tax credits to state incentives and even tiered pricing plans.
Using tax credits to install solar panels has been a popular choice for homeowners. The solar industry has led to many jobs and billions of dollars in investment. However, before you invest, you’ll need to understand your tax liability and any applicable incentives. You can also use a solar panel savings calculator to determine how much do solar panels save per month and ways to maximize it. In addition to the federal tax credit, many states offer tax credits. These may be applied to your income tax, state income tax, or alternative minimum tax. Some states may offer subsidized loans to help you finance your solar project. The federal tax credit is worth 30% of the cost of your solar system. This credit is valid for 10 years. It is called the Solar Investment Tax Credit (ITC). You must claim the credit on the first installation of your solar equipment.
State Government Incentives
Several states offer solar incentives and rebates to help reduce the costs of installing solar panels. Each state has a different set of programs, however. You should check with your local top solar companies to find out what financial benefits are available in your state. One of the most typical incentives for solar panels is the Solar Investment Tax Credit. It allows the owner to recoup up to 26% of the cost of the equipment. In addition to the federal tax credit, many states offer state tax credits. These credits can reduce your solar costs by up to $800. This tax credit can carry over for up to 10 years. Another type of incentive is the Solar Renewable Energy Certificate. Solar panels earn SRECs for every 1,000-kilowatt hours of electricity they produce. These certificates are purchased by utilities under state RPS standards and count towards their goals.
Solar panels can save you money on energy bills, but you must keep them in good working order. Depending on your location, the cost of maintaining your solar panels can be anywhere from $150 to $330 a year.
The most efficient way to do this is to hire a professional to do the dirty work. They can inspect your solar panel for damage and recommend repairs or replacements if necessary. This is a good idea because it reduces the risk of expensive repairs. The maintenance cost will vary depending on your location and the size of your solar array. The cost is usually less than a quarter of the initial purchase price. You can clean your panels yourself if you have a small rooftop system. However, if your roof is steep, you will likely need to hire a professional.
Tiered Pricing Plans
Installing a solar system is a great way to save money on your energy bill. But it is also important to understand your utility’s rate structure before you go solar. This will help you determine the size of your solar installation and how much money you can save on your electricity bill. One common approach to electric utility billing is tiered rates. These rates are based on the amount of energy used during a billing period. The prices increase when the user reaches a certain threshold. They also increase when overage occurs. These plans can apply to both commercial and residential customers. The best way to find out about these plans is to contact your electricity provider. They will provide you with an Electricity Facts Label describing the various rates. You can then switch to a time-of-use plan if you choose.
No Harmful Or Environmentally Damaging By-Products
Unlike natural gas and coal, solar energy does not create global warming emissions, and its life-cycle emissions are generally lower than those of natural gas. Still, some toxic materials are used in the manufacturing process of solar panels, which can cause the degradation of water resources and land and affect wildlife. Many solar panel manufacturers recycle by-products, but not all do. Some companies dump panels into municipal landfills or export them to third-world countries. Many solar panels contain heavy metals, which can leech into the ground and pose a health hazard to humans and plants. Toxic substances are also used to clean photovoltaic cells, but some manufacturers may not be responsible for ensuring that the chemicals are handled properly. The United States is the largest user of solar panels. However, only China and Europe have mandated that manufacturers be held accountable for the waste produced by their manufacturing process.
