Proto J7320MHT Impact Socket 1/2 in Drive 20mm

Product Description

The PROTO J7320MHT is a 20mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Built from alloy steel in a thin-wall profile, it delivers the torque transfer required for high-demand fastener work without sacrificing access in tight clearances. The overall length is 3.25 inches, making it suitable for a wide range of fastener depths. This socket is intended for professional use by mechanics, industrial maintenance technicians, and trade professionals who require durable, impact-rated tooling on the job.

This socket is well suited for automotive, heavy equipment, and industrial maintenance applications where 20mm hex fasteners are common. The thin-wall construction allows engagement in recessed or closely spaced bolt patterns where standard-wall sockets cannot fit. The 6-point drive geometry reduces the risk of fastener rounding under high torque, making it a reliable choice for stubborn or heavily torqued fasteners encountered in field and shop environments.

Key Features

• 1/2 inch drive size compatible with standard impact wrenches and ratchets
• 20mm socket size with 6-point drive geometry for secure fastener engagement
• Thin-wall profile allows access in tight or recessed bolt locations
• Alloy steel construction rated for impact tool use
• 3.25 inch overall length suits a variety of fastener depths

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive impact wrenches, torque wrenches, and ratchets in automotive, industrial, and mechanical maintenance applications.

Installation Notes

This socket is intended for use by qualified mechanics and maintenance technicians. Always verify the socket is fully seated on the fastener and drive tool before applying torque. Inspect the socket for cracks or wear before each use, and do not use impact-rated sockets with hand ratchets beyond their rated capacity. Discontinue use if any deformation or cracking is observed.
