Details

Strong, Precise Steel Bits

The 6-sided hexagonal tip is machined to precise tolerances for an exact fit with hex fasteners.

Two-Piece Design

Our two-piece bit socket design allows us to optimize the steel alloys, heat treatments, and forming processes for the bit and socket separately for a tool that’s higher performing and more durable than traditional one-piece impact bit sockets.

6140 Chromium-Vanadium (Cr-V) Steel Socket

Heat-treated to 40-47 HRC for use on impact wrenches. Coated with a corrosion-resistant manganese phosphate finish.

S2 Steel Bit

Heat-treated to 57-63 HRC to resist shocks and maintain geometry under stress.

Drive Tool Retention

Sockets work with both types of anvils found on 3/8 inch drive impact wrenches:

Two Size Markings

The size is marked in two ways on every socket: a high-visibility laser marking and a permanent stamped marking.
