Proto J07538M Impact Socket 3/4 in Drive 38mm 6-pt

Product Description

The PROTO J07538M is a 6-point impact socket designed for heavy-duty fastener removal and installation in professional trade and industrial environments. Built for use with 3/4 inch drive impact wrenches, it accepts a 38mm hex fastener and measures 2-23/64 inches overall length. The 6-point geometry delivers full contact on fastener flats, reducing rounding under high-torque impact loads. This socket is sized for large-diameter fasteners commonly encountered in mechanical, industrial maintenance, and heavy equipment applications. It weighs 1.56 pounds, reflecting the wall thickness and alloy construction expected of impact-rated tooling.

The J07538M fits 3/4 inch drive impact wrenches and torque multipliers used in industrial maintenance, fleet service, heavy equipment repair, and structural assembly work. The 38mm socket size is common on large hydraulic fittings, axle hardware, heavy machinery fasteners, and structural bolting applications. This socket is intended for use by professional mechanics, millwrights, ironworkers, and other tradespeople working with large-format fasteners requiring controlled high-torque drive.

Key Features

• 3/4 inch square drive fits standard heavy-duty impact wrenches and torque multipliers
• 38mm 6-point hex drive provides full flat contact for maximum torque transfer
• 6-point design reduces fastener rounding under high-impact loads
• 2-23/64 inch overall length suits most standard clearance applications
• Impact-rated construction handles the shock loads produced by pneumatic and electric impact tools

Compatibility

Designed as an OEM-style impact socket for use with 3/4 inch drive impact wrenches, ratchets, and torque multipliers accepting standard square-drive tooling.

Installation Notes

Install and remove using a 3/4 inch drive impact wrench or manual ratchet rated for the torque requirements of the application. Always confirm the socket is fully seated on the fastener before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if any damage is found. Do not use impact sockets with hand-drive tools that are not rated for impact loads.
