Proto J7216HF Impact Socket 3/8 in Drive 1/2 in Hex

Product Description

The PROTO J7216HF is a 6-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. It accepts a 1/2 inch hex fastener and is constructed from alloy steel for resistance to the high-torque stress of pneumatic and cordless impact tools. A built-in magnet retains the socket on the drive during positioning and helps hold fasteners during install. The overall length is 1-3/32 inches, making it suited for applications where a compact profile is required. This socket carries a lifetime warranty from PROTO.

This socket is intended for use in professional trade environments where impact-rated tooling is required. Typical applications include mechanical assembly, HVAC equipment installation, electrical panel work, and plumbing rough-in where hex-head fasteners are encountered. The compact 1-3/32 inch overall length allows work in tighter clearances without sacrificing drive engagement. The magnetic retention feature is especially useful on overhead or vertical fastening tasks.

Installation Notes

This socket is intended for installation by mechanics and trade professionals using 3/8 inch drive pneumatic, electric, or cordless impact tools. Confirm the drive tool is rated for impact use before attaching this socket. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets on manual torque wrenches, as impact-rated sockets are not calibrated for torque wrench applications.
