Proto J74422MP Impact Socket 1/2 in Drive 22mm 6-point

Product Description

The PROTO J74422MP is a 6-point impact socket designed for heavy-duty fastening and removal tasks in professional trade environments. Built from alloy steel, it accepts a 1/2 inch drive and fits 22mm hex fasteners. The overall length is 2-19/32 inches, keeping it compact enough for tight-clearance work. Manufactured to ASME B107.2 standards, this socket is engineered for use with pneumatic, hydraulic, and electric impact wrenches. It is a standard go-to for HVAC technicians, pipefitters, electricians, and general mechanical trades that rely on impact-rated tooling for daily service work.

The J74422MP suits residential and commercial service applications where 22mm fasteners are common, including equipment mounting hardware, flanged connections, and structural fasteners. Its universal style and 6-point geometry reduce fastener rounding under high-torque impact loads. This socket is appropriate for any trade professional using a 1/2 inch drive impact wrench on the job site, in the shop, or during field service calls.

Compatibility

Designed as an OEM-style replacement and standard fitment impact socket for 1/2 inch drive impact wrenches accepting 22mm 6-point hex sockets.

Installation Notes

Install and remove with a 1/2 inch drive pneumatic, hydraulic, or electric impact wrench. Verify the socket is fully seated on the drive before applying torque. Do not use impact sockets with standard ratchets or torque wrenches, as impact-rated and hand-tool-rated sockets are not interchangeable under dynamic load. Inspect for cracks or deformation before each use and replace any damaged socket immediately.
