Gearwrench 84577N Impact Socket 1/2 in Drive 19mm 6-pt

Product Description

The GEARWRENCH 84577N is a 19mm, 6-point impact socket built for 1/2 inch drive impact wrenches and rattle guns used in HVAC, plumbing, and general mechanical work. Manufactured from chromium-molybdenum steel with a black oxide finish, it is engineered to absorb the high-torque shock loads generated by pneumatic and cordless impact tools. High-visibility laser-etched size markings allow fast identification in a crowded tool bag, and secondary hard-stamped markings serve as a backup if the surface marking wears. The off-corner loading design contacts the flat faces of a fastener rather than the corners, reducing the risk of rounding fastener heads under load. Meets ASME B107.33M standards. Weighs 0.49 pounds.

This socket is suited for residential and commercial trade applications where 19mm metric fasteners are common — including equipment mounting hardware, pipe hangers, conduit supports, and mechanical-room installations. It is a metric-spec tool appropriate for service technicians, pipefitters, and electricians working on equipment with metric fastener patterns. The 6-point configuration is preferred for impact use because it distributes force more evenly than 12-point designs, especially on worn or corroded fasteners encountered in the field.

Key Features

• Chromium-molybdenum steel construction handles repeated impact torque without cracking or deforming
• Black oxide finish resists corrosion and reduces glare in work environments
• Off-corner loading design reduces fastener rounding on worn hardware
• High-visibility laser-etched size markings for fast socket identification
• Secondary hard-stamped size markings provide a permanent backup reference
• Meets ASME B107.33M standard for impact sockets

Compatibility

Designed for use with 1/2 inch drive impact wrenches, torque wrenches, and ratchets requiring a 19mm 6-point metric impact socket.

Installation Notes

This socket is installed and removed by hand onto any standard 1/2 inch square drive tool — no special tools required for attachment. Always confirm the socket is fully seated on the drive before applying torque. Do not use impact sockets on manual torque wrenches when a torque-limiting value is critical without verifying the socket meets the tool manufacturer specifications. Inspect the socket periodically for cracks, chips, or deformation and remove from service if any damage is found.
