Proto J5526 Hand Socket 13/16 in 3/4 Drive 12-point

Product Description

The PROTO J5526 is a 3/4-inch drive, 12-point hand socket sized at 13/16 inches, built for heavy-duty fastener work in professional trade environments. Constructed from alloy steel with a chrome-plated finish, this standard-length socket meets ASME B107.110-2012 dimensional and performance standards. At 2 inches overall length and a compact profile, it fits standard 3/4-inch drive ratchets and breaker bars. Licensed mechanics, industrial maintenance technicians, and HVAC service professionals rely on 12-point geometry for faster engagement on hex fasteners in tight clearance situations.

The J5526 is suited for residential and commercial mechanical service, heavy equipment maintenance, and industrial assembly where 3/4-inch drive tooling is required. The 13/16-inch socket size is commonly used on structural bolts, HVAC equipment frames, and large mechanical assemblies. It is designed for hand-tool use and is not rated for impact driver operation. Note that this socket is not tether-capable and is not intended for overhead work requiring tethered tool compliance.

Key Features

• 13/16-inch socket size with 12-point drive geometry for fast fastener engagement
• 3/4-inch drive compatible with standard ratchets and breaker bars
• Alloy steel construction for strength under high-torque hand operation
• Chrome-plated finish resists corrosion and simplifies cleaning
• Standard length at 2 inches overall for general-purpose reach
• Meets ASME B107.110-2012 for dimensional accuracy and performance

Compatibility

Designed for use with 3/4-inch drive ratchets, breaker bars, and extensions in standard hand-tool applications.

Installation Notes

This socket is intended for hand-tool use by qualified mechanics and service technicians. Ensure the drive tool is fully seated and the fastener is properly engaged before applying torque. Do not use this socket with impact drivers or pneumatic tools, as it is not impact-rated. Inspect for cracks or wear before each use and remove from service if damage is found.
