Proto J07520MT Impact Socket 3/4 in Drive 20mm 12-pt

Product Description

The PROTO J07520MT is a 20mm, 12-point impact socket designed for 3/4 inch drive impact wrenches and high-torque hand tools. Built from alloy steel, it delivers the wall strength and torsional durability required for heavy-duty fastening applications. The overall length of 1-29/32 inches keeps the profile compact for work in tighter clearances. This socket is intended for use by professional mechanics, industrial maintenance technicians, and trade contractors who rely on impact-rated tooling for demanding fastener removal and installation tasks.

This socket fits standard 3/4 inch drive impact wrenches and ratchets commonly found in automotive, heavy equipment, and industrial maintenance environments. The 20mm size is a common fastener dimension across metric bolt patterns on trucks, heavy machinery, and structural assemblies. The 12-point configuration allows engagement from multiple positions, which can simplify access when working around obstructions. It is suited to both shop and field use wherever a durable metric impact socket is required.

Key Features

• 3/4 inch drive for use with standard heavy-duty impact wrenches and ratchets
• 20mm socket size for common metric fastener applications
• 12-point design allows multiple engagement positions for easier placement
• Alloy steel construction provides impact-rated strength and wear resistance
• Compact 1-29/32 inch overall length for improved access in confined spaces

Compatibility

Designed as a standard 3/4 inch drive impact socket compatible with 3/4 inch drive impact wrenches, torque multipliers, and ratchets using a 20mm metric fastener engagement.

Installation Notes

This socket is intended for use by professional mechanics and maintenance technicians familiar with impact tooling. Always confirm the drive tool is rated for impact use before pairing with this socket. Inspect the socket for cracks or deformation before each use and replace if any damage is found. Do not use impact sockets as substitutes for hand-tool sockets on torque wrenches, as impact-rated and hand-rated sockets have different wall tolerances.
