Proto J75278P Impact Socket 1/2 in Drive 11/16 in 6-pt

Product Description

The PROTO J75278P is a 6-point hex drive impact socket designed for heavy-duty fastening and removal applications. Built from alloy steel, it accepts a 1/2 inch drive and fits 11/16 inch fasteners. The universal style and 3.5 inch overall length make it well-suited for use with pneumatic, hydraulic, and electric impact wrenches in professional service environments. This socket meets ASME B107.2 specifications, confirming it is manufactured to recognized industry dimensional and performance standards. Licensed tradespeople and experienced technicians reaching for reliable impact-rated tooling will find this socket delivers consistent performance across demanding fastener applications.

The J75278P is intended for use in automotive, mechanical, HVAC, plumbing, and general industrial service work where 1/2 inch drive impact tools are standard. It is appropriate for both shop and field use. The 6-point design reduces fastener rounding compared to 12-point configurations, making it a preferred choice when working with worn or corroded hardware. Its alloy steel construction handles the repeated shock loads generated by impact drivers without deforming or cracking under normal use conditions.

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive pneumatic, electric, or hydraulic impact wrenches in professional trade and industrial applications.

Installation Notes

Impact sockets should only be used with impact-rated drive tools. Never use standard chrome hand-tool sockets with impact wrenches, as they are not rated for shock loads and may fracture. Ensure the socket seats fully on the fastener before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
