Proto J5422MH Hand Socket 22mm 6-point 1/2 Drive

Product Description

The PROTO J5422MH is a 22 mm, 6-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and torque wrenches. Built from alloy steel with a chrome-plated finish, this standard-length socket delivers solid corrosion resistance and a clean appearance suited to professional toolboxes. At 1-17/32 inches overall length, it fits tight clearances while maintaining enough wall thickness for consistent torque transfer on fasteners. Meets ASME B107.5 standards for hand socket tools, confirming dimensional and strength compliance for trade use. It weighs 0.26 pounds and is not tether capable.

This socket is appropriate for automotive service, heavy equipment maintenance, industrial assembly, and general mechanical work wherever a 22 mm fastener is encountered. The 6-point geometry reduces contact stress on fastener flats compared to 12-point designs, making it particularly useful on worn or corroded hardware. Standard-length profile suits most open-access fastener locations in both shop and field environments. Suitable for use by mechanics, millwrights, fleet technicians, and maintenance professionals.

Compatibility

Compatible with 1/2 inch drive ratchets, torque wrenches, extensions, and breaker bars following standard ASME B107.5 drive geometry.

Installation Notes

Confirm the drive tool is rated for the torque being applied before use. Inspect the socket for cracks or deformation before each use, and remove from service if any damage is found. Do not use impact drivers with this hand socket unless the tool is rated for impact use. Keep drive surfaces clean and free of debris to ensure proper seating on fasteners.
