Proto J7320M Impact Socket 1/2 in Drive 20mm 6-point

Product Description

The PROTO J7320M is a 20mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Built for high-torque applications, this socket features a hex drive style and measures 3.25 inches in overall length. The 6-point design maximizes contact with fastener flats, reducing the risk of rounding under load. Weighing 0.55 pounds, it is sized for professional use in automotive, industrial, and mechanical service environments. Licensed technicians and trade professionals who regularly work with impact tooling will find this socket suited to demanding fastener-removal and installation tasks.

This socket is intended for use in automotive repair, fleet maintenance, heavy equipment service, and general mechanical assembly where a 20mm fastener size is common. The 1/2 inch drive connection pairs with standard impact wrenches, torque wrenches, and ratchet handles commonly found in professional shops and field service kits. The 3.25 inch overall length provides clearance in recessed or tight fastener locations without sacrificing stability on the drive end.

Installation Notes

This socket is installed and used by automotive technicians, fleet mechanics, and industrial maintenance professionals.
