The bench drill is used for drilling holes through materials including a range of woods, plastics and metals. It is normally bolted to a bench so that it cannot be pushed over and that larger pieces of material can be drilled safely. The larger version of the machine drill is called the pillar drill.

A Keps nut, (also called a K-nut[1] or washer nut), is a nut with an attached, free-spinning washer.
It is used to make assembly more convenient. Common washer types are star-type lock washers, conical, and flat washers.
Keps is a trademark of ITW Shakeproof. The name comes from "kep" in Shakeproof, and the "s" is because usually more than one are purchased.
