Tekton SIB91104 3/8" Drive Triple Square Impact Bit Socket Set

• 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
