Proto J7210HF Impact Socket 3/8 in Drive 5/16 in Hex

Product Description

The PROTO J7210HF is a 6-point hex drive impact socket designed for use with 3/8 inch drive impact wrenches and rattle guns. Built from alloy steel with a magnetic design, it accepts a 5/16 inch hex fastener and measures 1-3/32 inches in overall length. The magnetic retention keeps the fastener seated during positioning, reducing drops in tight or overhead work. This socket is suited for HVAC technicians, plumbers, electricians, and general trade professionals who work with hex-head fasteners on equipment panels, flanges, and mechanical assemblies.

The J7210HF fits standard 3/8 inch drive impact tools and is appropriate for both residential and light commercial service work. It is a compact, single-socket solution for 5/16 inch hex fasteners commonly found on equipment access panels, electrical enclosures, ductwork hardware, and similar mechanical connections. The alloy steel construction handles the torsional stress produced by impact drivers without cracking or rounding.

Installation Notes

This socket is intended for use by trade professionals working with 3/8 inch drive impact tools. Ensure the drive tool is powered down or the air supply is disconnected before changing sockets. Confirm the socket is fully seated on the drive anvil before applying torque. Do not use impact sockets on manual torque wrenches where calibrated torque values are required.
