Square Drive Screws

The square drive recess was the first recess-type drive developed for large scale screw production. Today, a century later, square drive screws and the driver bits are now widely available, economical and offer many advantages over other drive systems:

 

For higher torque applications:

The geometry of the square drive allows for the delivery of greater torque to the screw head by providing an improved contact area with the surface of a properly inserted driver bit. Consequently, the driver bit resists cam out. For this reason, the square drive is often preferred for applications where greater torque is required (eg. woodworking). Furthermore since the driver bit sits better in the square recess, there is also less slippage and reduced marring of the surface of the material into which the screw is being inserted.

 

For greater ease of use:

Since it is a square recess, there are four possible positions to insert the driver making it effectively self-aligning. Also because of the shape and depth of the recess, the screw remains on the driver bit making it ideal for use in tight spaces and for single hand insertion.
