Proto J77277P Impact Socket 3/8 in Drive 5/8 in 6-point

Product Description

The PROTO J77277P is a 6-point hex drive impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. Built from alloy steel, this socket delivers the toughness needed to withstand the high-torque demands of impact tooling. The 5/8 inch socket size and 2-3/32 inch overall length make it a practical choice for fastener work in tight or standard access situations. It meets ASME B107.2 specifications, confirming dimensional and performance compliance for professional use. HVAC technicians, plumbers, electricians, and general trade professionals will find this socket a reliable addition to an impact-rated socket set.

This socket is suited for residential and commercial service work where a 3/8 inch drive impact tool is the preferred choice. The universal style fits common impact wrench and ratchet configurations. At 2-3/32 inches overall length, it works well in moderate-clearance applications without the bulk of deep-well sockets. Trade professionals use this size frequently when working on equipment panels, conduit fittings, pipe flanges, and mechanical fasteners across HVAC, plumbing, and electrical installations.

Installation Notes

This socket is intended for use with 3/8 inch drive impact-rated tools only — do not use on non-impact ratchets where alloy steel impact sockets may present a safety risk due to different metallurgical tolerances. Always inspect the socket for cracks or wear before use. Ensure the drive tool is powered down or depressurized before changing sockets. Follow applicable workplace safety codes when using pneumatic or electric impact tools on the job site.
