Proto J15050L Impact Socket 1-1/2 in Drive 3-1/8 in 6-point

Product Description

The PROTO J15050L is a heavy-duty impact socket designed for high-torque fastening applications in industrial, mechanical, and fleet maintenance environments. Built from alloy steel, this 6-point socket features a 1-1/2 inch drive and a 3-1/8 inch socket size, with an overall length of 6-3/8 inches. The 6-point hex drive geometry concentrates force on the flat sides of fasteners, reducing rounding and improving grip under high-impact loads. At 18.89 pounds, this is a substantial tool suited for large fastener work on heavy equipment and structural assemblies. Compliance with ANSI Spec B107.2 confirms it meets dimensional and performance standards for impact-rated sockets.

This socket is intended for use with 1-1/2 inch drive impact wrenches and torque multipliers common in heavy equipment service, truck and bus maintenance, large-scale industrial assembly, and infrastructure maintenance. The 3-1/8 inch socket size addresses large-diameter fasteners found on axles, heavy flanges, structural bolting, and industrial machinery. Licensed mechanics, millwrights, and heavy equipment technicians are the primary users.

Installation Notes

This socket is intended for use by qualified mechanics and technicians working with impact-rated drive tools only — do not use with standard hand-drive ratchets or breaker bars not rated for impact service. Ensure the drive tool is depressurized or powered down before attaching or removing the socket. Inspect the socket for cracks, chips, or deformation before each use and remove from service if damage is found. Follow applicable workplace safety standards and equipment manufacturer torque guidelines when tightening large-diameter fasteners.
