Mayhew Triple Square Socket Bit

The Mayhew Triple Square Socket Bit is a drive tool for turning triple square (XZN) fasteners. You may also see it called a triple square bit socket or an XZN insert socket bit. It pairs a triple square bit with a square drive socket body, so you can use it with a standard ratchet or breaker bar. Triple square fasteners are common in automotive drivetrain, suspension and engine applications, and the 12-point spline pattern lets the tool grip them securely.

Key Features:

• Triple square (XZN) bit profile for 12-spline fasteners
• Tool steel construction for strength and durability
• Square drive design works with standard ratchets and breaker bars
• Made by Mayhew, a long-established maker of professional hand tools
• Available in multiple sizes in this product line

Mayhew builds its professional-grade tools for repeated use in shop and field work. This socket bit gives you a reliable way to work on triple square fasteners without stripping the heads.
