Proto J07520M Impact Socket 3/4 in Drive 20mm 6-point

Product Description

The PROTO J07520M is a 3/4 inch drive impact socket designed for heavy-duty fastening and removal applications in industrial, mechanical, and automotive service environments. Built with a 6-point hex drive profile and a 20mm socket size, it delivers solid wall contact on fastener flats to reduce rounding under high-torque impact loads. The overall length of 1-59/64 inches keeps the profile compact for use in tighter spaces. This socket is intended for use with 3/4 inch drive impact wrenches and is the type of tool installed and used daily by professional mechanics, millwrights, and maintenance technicians.

This socket suits applications where a 3/4 inch drive impact tool is required, including heavy equipment maintenance, fleet service, structural fastening, and industrial assembly. The 20mm size covers common metric fastener sizes found on commercial vehicles, agricultural equipment, and machinery. The 6-point design is preferred in high-torque impact work because it distributes force across the full flat of the fastener, reducing the risk of slippage or fastener damage under load.

Key Features

• 3/4 inch drive size compatible with standard 3/4 inch drive impact wrenches and ratchets
• 20mm socket size for common metric fastener applications
• 6-point hex drive profile maximizes contact area and reduces fastener rounding
• Compact overall length of 1-59/64 inches for use in space-limited access points
• Designed for impact use, not intended for hand-torque-only applications

Compatibility

Designed as an OEM-style replacement or service socket for use with 3/4 inch drive impact tools requiring a 20mm 6-point hex socket.

Installation Notes

This socket is installed and removed by hand onto a 3/4 inch drive impact wrench or ratchet. Confirm the fastener size matches 20mm before applying torque to avoid fastener damage. Always use impact-rated sockets with pneumatic or electric impact tools. Inspect the socket for cracks or wear before each use and retire any socket showing deformation or surface fatigue.
