Proto J7213MHF Impact Socket 3/8 in Drive 13mm 6-pt

Product Description

The PROTO J7213MHF is a 6-point impact socket designed for use with 3/8 inch drive impact wrenches and rattle guns. Built from alloy steel, it accepts a 13mm fastener and measures 1-3/16 inches overall length. The magnetic design helps retain the socket on the fastener during positioning, which is useful in tight or overhead applications. This socket is suited for automotive, mechanical, HVAC equipment fastening, and general trade use wherever a 3/8 inch drive impact tool is the preferred driver. The alloy steel construction is rated for the high-torque, high-cycle demands of impact tooling.

This socket is appropriate for residential and commercial service work, including HVAC unit assembly and disassembly, plumbing fixture installation, and general mechanical fastening tasks. The 6-point contact geometry reduces the risk of fastener rounding compared to 12-point designs, making it preferable for seized or heavily torqued fasteners. It is a single-piece, standard-depth socket intended for use by licensed trade technicians and experienced maintenance professionals who rely on 3/8 inch drive impact sets.

Installation Notes

Install and remove using a 3/8 inch drive impact wrench or hand ratchet. Inspect the socket for cracks or deformation before each use and replace if damaged. Do not use impact sockets on hand tools beyond their rated torque range, and do not use standard chrome hand-tool sockets on impact drivers. Follow applicable workplace safety and tool-use standards for the trade in which this socket is deployed.
