Proto J7222M Impact Socket 3/8 in Drive 22mm 6-point

Product Description

The PROTO J7222M is a 6-point impact socket designed for heavy-duty fastener work in professional trade and industrial environments. Built for 3/8 inch drive impact wrenches, it accepts a 22mm hex fastener and measures 1-3/32 inches overall length. The 6-point design concentrates force on the flat faces of a fastener rather than the corners, reducing the risk of rounding under high torque. This socket is intended for use by mechanics, pipefitters, electricians, and other tradespeople who rely on impact-rated tooling for production or service work.

The J7222M fits standard 3/8 inch drive impact wrenches and air tools commonly used in HVAC service, plumbing rough-in, electrical panel installation, and general mechanical assembly. Its compact 1-3/32 inch overall length makes it practical in confined spaces where longer sockets would be obstructed. The 22mm size covers a range of metric fasteners found on equipment housings, flanges, and structural connections across residential and commercial trade applications.

Installation Notes

Install and remove using a 3/8 inch drive impact wrench, air ratchet, or hand ratchet. Verify the socket is fully seated on the drive anvil and the fastener before applying torque. Do not use impact sockets with standard chrome hand-tool ratchets beyond their rated capacity. Inspect the socket for cracks or deformation before each use and replace if damage is found.
