Gearwrench 84571N Impact Socket 1/2 in Drive 13mm

Product Description

The GEARWRENCH 84571N is a 6-point impact socket designed for high-torque fastening applications in automotive, mechanical, and industrial service work. Built from chromium-molybdenum steel with a black oxide finish, this socket handles the stress of impact driver use without cracking or deforming. The 13mm socket size fits a 1/2 inch square drive and delivers reliable engagement on metric hex fasteners. High-visibility laser-etched markings allow quick size identification in low-light shop conditions, while secondary hard-stamped size markings serve as a backup if surface markings wear. Licensed technicians and professional mechanics reach for this socket during drivetrain, suspension, and general powertrain work.

This impact socket is suited for professional use in automotive repair shops, fleet maintenance facilities, and industrial service environments. The 6-point design limits contact to the flat faces of a fastener rather than the corners, reducing the risk of rounding under high torque. The off-corner loading geometry makes it particularly effective on metric fasteners that see frequent removal and reinstallation cycles. It is sold individually and is appropriate for both air-driven and cordless impact wrenches using a 1/2 inch drive.

Key Features

• Chromium-molybdenum steel construction rated for impact tool use
• 6-point hex drive with off-corner loading design reduces fastener rounding
• Black oxide finish resists corrosion and reduces glare
• High-visibility laser-etched markings for fast size identification
• Secondary hard-stamped size markings provide a permanent backup reference
• Meets ASME B107.33M standards for impact socket performance

Compatibility

Designed for use with 1/2 inch drive impact wrenches and ratchets accepting standard square drive tools. Fits 13mm metric hex fasteners. Compatible with air-driven and cordless impact drivers in the 1/2 inch drive class.

Installation Notes

Install and remove this socket with impact-rated drive tools only — do not use standard chrome hand-tool sockets on impact drivers. Ensure the socket is fully seated on the drive anvil and the fastener before applying torque. Disconnect power or air supply before changing sockets on pneumatic or cordless impact tools. Inspect the socket for cracks or deformation before each use and replace if damage is found.
