Every good handy man knows the value of using the right screwdrivers. Learn how to choose, use properly for your tools.
Slotted Screwdriver
The most common screwdriver is the standard slotted, for use with screws that have a single slot.
Slotted screwdrivers are available in a wide range of lengths and blade sizes. Toolprice carries wide range screwdriver sizes for any application. Use models with flared or winged tips for screws whose heads rest on the surface of the work. Models with parallel-sided tips are better for screws whose heads are driven below the surface; driving these with a flared tip could mar the wood.
Using a Slotted Screwdriver
To drive a screw, grip the screwdriver with your thumb forward. Bear down just enough to seat the blade in the slot, and turn the tool clockwise.
Always use a screwdriver tip of the proper size. A tip that's too narrow can strip the screw head, and an overly wide head can damage the work. Though you may have to bear down on the screwdriver to firmly seat its tip in the screw head, remember that screws are driven by torque, not by pressure.
Phillips Screwdriver
A Phillips screwdriver is designed to fit into a Phillips-head screw, which has two crossing slots. The screwdriver's cross design prevents the driver from slipping out of the screw, as often happens if you use a standard screwdriver for the same job. Phillips screwdrivers come in five sizes, from the smallest, 0, through to the largest, 4.
Always use a screwdriver tip of the proper size. A tip that's too small can strip the screwhead. Though you may have to bear down on the screwdriver to firmly seat its tip in the screwhead, remember that screws are driven by torque, not by pressure.
Nut Driver
A nutdriver is used like a screwdriver to turn hexagonal nuts and bolts. It comes with a screwdriver-style handle.
Some models come in color-coded or marked sets to make it easy to identify the size. Toolprice is your source of nut driver for home, auto shop repair, weekend warrior.
Cordless Screwdriver
With a cordless power screwdriver, you can drive a large number of screws without tiring your hands. A switch changes the direction of rotation, allowing you to both drive and remove screws. Some models plug directly into a charging unit to replenish the batteries. Others have a removable battery, so you can recharge one while using another.
Always use a screwdriver bit of the proper size. A bit that's too small can strip the screwhead. Though you may have to bear down on the screwdriver to firmly seat its bit in the screwhead, remember that screws are driven by torque, not by pressure.
Cordless power screwdrivers come with interchangeable slotted and Phillips-head bits of various sizes. Some models have a locking shaft so you can operate them by hand, for extra torque.
