TEKTON 3/8 Inch Drive x 1/4 Inch Hex Impact Bit Socket | SIB12206

Precise Bit Geometry - The bit tip is machined to precise tolerances for an exact fit with hex fasteners Optimal Two-Piece Design - We use separate steel alloys and processes for the bit and socket, resulting in a higher performing tool than one-piece designs Permanent Connection - The bit is pressed directly into the socket for a permanent connection that won't loosen over time or under stress Two Size Markings - The size is marked with a high-visibility laser marking and a permanent stamped marking that won't rub off Friction Ring or Detent Pin Anvils - Smooth walls inside the drive end and a detent pin hole make the bit sockets compatible with both drive tool anvil types
