Proto J7322M Impact Socket 1/2 in Drive 22mm 6-point

Product Description

The PROTO J7322M is a 6-point impact socket designed for heavy-duty fastener work in professional trade environments. Built for a 1/2 inch drive, it accepts a 22mm hex fastener and measures 3.5 inches overall length. The 6-point design concentrates force on the flat faces of the fastener rather than the corners, reducing the risk of rounding under high-torque impact loads. This socket is suited for mechanics, HVAC technicians, electricians, and plumbers who rely on impact wrenches for equipment installation, removal, and service work. It is sold individually as a single-piece unit.

This socket fits standard 1/2 inch drive impact wrenches and is appropriate for both residential and commercial service applications. Common uses include fastening and loosening hex-head bolts and nuts on mechanical equipment, pipe flanges, electrical enclosures, and HVAC unit assemblies. The 22mm size is frequently encountered on metric fasteners across a wide range of mechanical and plumbing systems. Its impact-rated construction makes it suitable for air-driven and cordless electric impact wrenches used in the field or shop.

Installation Notes

Installation and removal tasks using this socket should be performed by qualified tradespeople familiar with impact tool operation. Always verify the drive size of the impact wrench matches the 1/2 inch drive before use. De-energize, depressurize, or lock out equipment before accessing fasteners on live mechanical or electrical systems in accordance with applicable safety codes. Do not use impact sockets with hand-torque ratchets, as impact-rated and hand-tool-rated sockets have different material specifications.
