Specialty screwdrivers include features that let you drive screws more quickly and in difficult spaces. These hand tools are durable, are dependable and require no power, so they're always ready to work.
Insulated screwdrivers are a must for electrical work. They don't conduct current, so you can work in safety. These screwdrivers come in all commonly used sizes to install electrical hardware.
A screw-holding screwdriver keeps the screw securely on the tip of your driver. You can use them to accurately start a screw and then tighten it with a regular screwdriver. Square screwdrivers (Robertson) take advantage of their screws' deeply recessed heads to hold the screw on the tip and many angles for easy starts and removal. It's also very easy to start a square bit compared to others, like slotted-head screwdrivers, since it easily slips into the screw.
An offset screwdriver features a crank-like handle. You can press it into the screw head and then turn it in a circular motion instead of a twisting motion for greater speed and less hand strain. They have two different heads, so you could use one side as a Phillips-head screwdriver and another for slotted or other types of screws. A ball-end screwdriver looks much like a regular hex-head driver, but it has a rounded end that can turn a fastener even if you have to hold it at an angle. This is very handy when you're working in confined spaces.
These drivers augment the capabilities of your current screwdriver sets. They can reach where other drivers don't and spin quickly. Review the job specifications of your project and determine the tools that you need, and then select the best specialty screwdriver to get the most professional results for your task.
