37 mm Impact Socket

The TEKTON SID22137 is a 1/2 inch drive impact socket built for professional mechanics and serious DIY users who need reliable fastener removal. Its 6-point opening grips hex fasteners on the flat sides to prevent rounding. High-visibility laser and permanent stamped markings make size identification quick in low light. The socket fits both friction ring and detent pin anvil types.

Upgrade From Worn Sockets

This socket replaces damaged or illegible sockets that slip on fastener corners. The radiused corner design applies torque to flat surfaces instead of edges, reducing round-off on stubborn bolts. It meets at least 1.3 times the ANSI/ASME proof torque standard, providing a measurable strength margin over older or lower-grade tools. The jump is worth it when fastener damage or marking wear slows down the job.

For High-Torque Impact Work

Ideal for technicians running 1/2 inch impact guns on automotive and heavy equipment fasteners. The detent pin hole allows optional positive retention on compatible anvils. Not suited for hand ratchet-only users who do not need impact-rated thickness. Buyers needing SAE sizes or smaller drive formats should look at other listings.
