Square Recess Bits

While there are countless electric and electronic appliances that use different fasteners, the huge availability of variously shaped bits can create some confusion. Square recess bits are well-known to professionals who have to deal with large screwing rates. They are especially popular in construction, carpentry, and woodworking. The tapered square nose prevents slippages and speeds up the job remarkably. Moreover, fewer slippages mean fewer damages to workpieces and smoother workflow. Square recess or simply square bits are also called Robertson bits, after the name of their inventor.

These tools offer many advantages including high torque and self-centering. Robertson bits follow a unique classification where different sizes are identified by a scale that starts with #0 and goes up to #3. Each size is identified by a color. For example, #3 driver bits are identified by the black color, their length ranges from 1” to 6”, and they are suitable for #12 and #14 Robertson screws.
