Lisle 13240 Hex Twist Socket - 21mm

The Lisle 13240 is a 21mm hex and twist socket designed for removing damaged, rounded, or rusted fasteners. This specialized socket features a unique twist design that bites into compromised bolt heads and nuts, providing the grip needed when standard sockets fail.

Key Features:

• 21mm hex size for common automotive applications
• Twist socket design grips damaged and rounded fasteners
• Hardened steel construction for durability
• Works with standard 1/2-inch drive ratchets and breaker bars
• Also available as part of Lisle 13420 hex and twist socket set

This socket is particularly useful for suspension work, exhaust system repairs, and any situation where fasteners have been compromised by corrosion or over-torquing. The aggressive internal design locks onto the fastener to prevent further rounding while maximizing removal torque.
