Nonmarring 6-Point Impact Sockets
Tighten or loosen nuts and bolts without damaging the finish. The tough steel core of the socket withstands the high torque of impact tools, but the insert and outer sleeve are made of plastic, which won’t scratch chrome plating and other coatings. Remove the outer sleeve for a thinner profile when working in tight spaces. Each size is a different color for easy identification.

Nonmarring 6-Point Sockets
Tightly grip nuts and bolts with hand-driven tools, leaving finishes unscratched. With a six-point shape, these sockets give you maximum leverage and prevent rounding while turning hex head fasteners. They contain a plastic insert, so they won’t damage highly polished finishes or coatings. Since they help maintain smooth surfaces where bacteria can’t grow—and also because they’re FDA compliant for direct contact with food—these sockets are commonly used in food, beverage, and pharmaceutical facilities. An O-ring grip keeps the insert secure in sockets during use, and also lets you replace worn-down inserts by hand.
