Proto J6505MH Impact Socket 1/4 in Drive 5mm 6-point

Product Description

The PROTO J6505MH is a 5mm, 6-point impact socket designed for use with 1/4 inch drive impact wrenches and ratchets. Built from alloy steel, this socket delivers the toughness needed for high-torque impact applications without cracking or rounding under load. At 2 inches overall length, it fits into tight spaces while maintaining solid fastener engagement. The hex drive configuration transfers torque directly to the fastener flat, reducing the risk of cam-out on stubborn hardware. This socket is used by mechanics, maintenance technicians, and trade professionals who require a reliable metric socket for impact tool use.

This socket fits production and service environments where 5mm metric hex fasteners are common, including automotive, HVAC equipment panels, electrical enclosures, and light industrial machinery. The 1/4 inch drive size makes it well suited for lower-torque impact work and in applications where a smaller drive is preferred for access or tool availability. Its compact overall length of 2 inches allows use in confined areas without sacrificing engagement depth.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit socket for 1/4 inch drive impact wrenches, impact drivers, and ratchets accepting standard hex drive accessories.

Installation Notes

This socket is intended for use by qualified mechanics and trade technicians familiar with impact tool operation. Ensure the socket is fully seated on the drive anvil before applying torque. Do not use impact sockets with hand-torque tools beyond their rated capacity, and inspect for cracks or deformation before each use. Follow applicable safety standards for hand and power tool operation in your facility or jobsite.
