SCREWDRIVERS• A screwdriver is a tool, manual or powered, for

turning (driving or removing) screws. Handles of screwdrivers are most commonly made from a plastic resin or wood and can sometimes even have a rubberised covering to improve grip. The two most common screwdrivers tips available are the Standard (or Flat tip) screwdriver used for screws with slotted heads, and the Phillips (or Cross-head) screwdriver which is used for screws with cross shaped recesses in the head.

Standard or Flat Tip Screwdrivers

• The most commonly found screwdrivers are the Standard or Flat Tip screwdriver, which matches screws with a vertical slot through their heads. Always ensure the tip of the screwdriver fits neatly into this slot and does not slip when being turned. The tip of the screwdriver should also be the same width as the screw head.

Standard or Flat Tip Screwdrivers

Phillips Head Screwdrivers (MOST COMMONLY USED)

• The second most commonly found type of screwdriver, the Phillips or Cross-head screwdriver, has an x-shaped head that matches the “X “on the head of the screw. Once securely seated in the Phillips head screw, the operator can apply much more torque for fastening. This screwdriver is purposely designed to come out or slip once the screw is in place securely. The user can thus have far more control over the tightening procedure.

Offset Screwdrivers• This type of screwdriver is shaped like a

letter “z” and has a variety of different tips. It is specifically designed for use in small or awkward spaces.

Allen Key or Hex Key

• Another rather surprising addition to the “screwdriver” stable – an Allen key is however still one by definition. An Allen key is an L-shaped piece of metal with a hexagonal head. Allen screws are often found on bicycle seats and on some D.I.Y furnishings.
