Proto J5020M Deep Hand Socket 20 Mm 12-point 3/8 Drive

Product Description

The PROTO J5020M is a 20 mm, 12-point deep hand socket with a 3/8 inch drive, designed for professional hand-tool use in mechanical, HVAC, plumbing, and electrical service work. Built from alloy steel with a chrome-plated finish, it measures 2.75 inches in overall length and weighs 0.33 pounds. The 12-point configuration provides more engagement positions than a 6-point socket, making it easier to fit onto fasteners in tight spaces. It meets ASME B107.5 standards, confirming dimensional and strength compliance for trade use.

This deep socket is suited for applications where a standard-length socket cannot reach recessed or extended fasteners. Typical scenarios include working on flanged fasteners, long bolt stud assemblies, and deeply set hex-head bolts found in mechanical systems and equipment enclosures. The deep length clears bolt protrusion while maintaining secure drive engagement, making it a practical addition to any service technician's socket set.

Key Features

• 20 mm socket size with 12-point design for wider engagement positioning on fasteners
• 3/8 inch drive compatible with standard 3/8 drive ratchets, extensions, and torque wrenches
• Deep length at 2.75 inches overall to reach recessed or stud-mounted fasteners
• Alloy steel construction with chrome-plated finish for corrosion resistance and durability
• Meets ASME B107.5 standards for hand socket tools

Compatibility

Designed for use with standard 3/8 inch drive hand tools including ratchets, breaker bars, and torque wrenches. Compatible with 20 mm hex-head fasteners across a wide range of mechanical and trade service applications.

Installation Notes

This socket is intended for use by mechanics and trade professionals with standard 3/8 inch drive hand tool sets. Ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Do not use with impact drivers unless the socket is rated for impact use. Inspect for cracks or wear before each use and replace if the socket shows signs of deformation.
