Details
Strong, Precise Triple Square Bits
The triple square (also called XZN) tip is machined to precise tolerances for an exact fit with triple square fasteners.
90º Geometry
The internal star shape is formed by 3 squares superimposed, each with a 30º offset. The points are shaped to an internal angle of 90º, different from double-hex geometries.
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.
Portable Socket Rail
Keep your sockets organized and ready to go using the included socket rail. The twist-to-lock clips hold sockets securely and can be repositioned anywhere along the rail.
