Proto J7327M Impact Socket 1/2 in Drive 27mm 6-point

Product Description

The PROTO J7327M is a 27mm, 6-point impact socket designed for 1/2 inch drive impact wrenches and rattle guns. Built for heavy-duty fastener work, it measures 3.5 inches overall length, giving techs enough reach for recessed fasteners without sacrificing control. The 6-point Hex drive geometry engages fastener flats squarely, reducing rounding and slippage under high-torque impact loads. This socket is a standard addition to professional service tool sets used in mechanical, HVAC, electrical, and general trade maintenance work where impact-rated tooling is required for safe and efficient operation.

The J7327M suits applications across automotive, mechanical, and trade service environments where 27mm fasteners are encountered. Common use cases include equipment assembly, structural fastener work, and heavy equipment maintenance requiring impact-rated sockets. The 1/2 inch drive interface matches a wide range of professional impact wrenches and torque tools. Its 3.5 inch overall length accommodates standard and moderately recessed bolt heads encountered in typical field and shop service scenarios.

Key Features

• 1/2 inch drive interface compatible with standard impact wrenches and drive tools
• 27mm socket size for metric fastener applications
• 6-point Hex drive geometry minimizes fastener rounding under high-torque impact loads
• 3.5 inch overall length provides reach for recessed fastener access
• Impact-rated construction designed to withstand repeated shock loading from pneumatic and electric impact tools

Compatibility

Designed as an OEM-style replacement or standard addition for use with 1/2 inch drive impact wrenches and torque tools requiring a 27mm, 6-point metric impact socket.

Installation Notes

Impact sockets should be installed and removed by qualified mechanics or trade professionals familiar with impact tooling. Always ensure the socket is fully seated on the drive square before applying torque. Do not use impact sockets with standard hand-drive ratchets, as impact-rated and chrome hand-tool sockets are not interchangeable for safety reasons. Inspect sockets regularly for cracks, deformation, or wear and remove from service if damage is found.
