Precise Triple Square Geometry – The triple square (also called XZN) tip is machined to precise tolerances, 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.

Sizes are marked both with a high-visibility laser marking and a permanent stamped marking that won’t wear off, Triple square (XZN) S2 steel bit tips are machined to precise tolerances for strong engagement with fastener heads, Two-piece design allows bit and socket to be optimized separately, for a more durable tool than traditional one-piece designs, Drive end is made of 4140 chromium-molybdenum (Cr-Mo) steel and properly heat-treated for use on impact wrenches, Twist-to-lock socket rail organizes and securely holds sockets in place, both for in your toolbox and on the go.
