Screwdrivers are essential hand tools for any toolbox to be complete. Whether you need a screwdriver or a bit set, Telenco store provides a wide range of ergonomic screwdrivers and high quality bits for technicians, craftspeople and field engineers. Having the suitable fastening tool is important to quickly perform a task with precision: there are many screwdriver bit types and lengths to choose from depending on the material and applications. You can find all-in-one screwdrivers with a handle, shank, and blade, or screwdriver sets with a single handle and a variety of interchangeable bits.

What are the different types of screwdriver heads?

Screwdrivers are divided mainly according to their head which must match the fastener head you need to screw or unscrew. While it is possible to use a flathead screwdriver on Phillips or Pozidriv screws, it could take more time and the result is not optimal. Indeed, using a screwdriver on a screw with a different pattern makes it extremely difficult to screw in, and almost impossible to unscrew. In either case, you could damage the screw head and render it unusable.

• Flat or slotted screwdriver heads are compatible with flat head, Phillips and Pozidriv screws but may rip when forced
• Cruciform or Phillips-heads are compatible with Phillips and Pozidriv screws and provide a better grip than the flat head
• Pozidriv screwdrivers have a cruciform head with a second offset cross. They offer an even better grip than the cruciform head, especially when you need to force
• Torx screwdriver heads offer the best clamping performance

Choosing a screwdriver depending on the handle

The length of the handle is also important: while a short handle transmits more force, a long handle allows you to reach areas that are more difficult to access. A bit holder screwdriver is like the Swiss Army knife of screwdrivers: it usually comes with a screwdriver bits set and can be adapted to your needs, avoiding the need to change tools each time. More specific screwdrivers are also available. For example, precision screwdrivers have a much thinner shaft for tightening and loosening extra-small screws. The handle grip is particularly important for precision screwdrivers because it needs to offer control while working in challenging situations.

If you plan on using your screwdriver near any kind of live electrical wiring, you’ll need to use a VDE approved insulated screwdriver. Unlike standard screwdrivers that have a bare metal shaft that can easily conduct electricity, VDE screwdrivers are covered with a nonconductive plastic material. There are essential in any electrician’s toolbox. This not only increases user safety, but also reduces the chances of accidental damage to the components you’re working on.

To sum-up, standard handle types usually have a bi-material coating and are ideal for conventional driving on non-electrical work. Screwdrivers with long and thin handle have a small head for precise screwdriving. A short ball-shaped handle offers a better grip for a tenfold increase in screwing power while insulated screwdriver handle are indispensable for live electrical work.
