Proto J5430M 30mm 12-point 1/2 Drive Hand Socket

Product Description

The PROTO J5430M is a 30 mm, 12-point hand socket built for professional mechanical and maintenance work. It features a 1/2 inch drive and is machined from alloy steel with a chrome-plated finish that resists corrosion and simplifies cleanup. The overall length is 1-25/32 inches, placing it in the standard-length category. This socket meets AS4984A and ASME B107.110-2012 standards, making it suitable for critical fastening applications where compliance matters. Technicians in automotive, industrial, and general mechanical trades reach for this socket when working with larger hex fasteners on equipment, drivetrain components, and heavy machinery assemblies.

This socket is designed for hand-tool use in standard-reach applications where a deep socket is not required. The 12-point geometry provides more engagement positions around a fastener, which is useful in tight spaces where swing arc is limited. It fits standard 1/2 inch drive ratchets, breaker bars, and torque wrenches. Typical use cases include automotive service, fleet maintenance, and industrial equipment repair where 30 mm fasteners appear on wheel hubs, axle nuts, suspension components, and large structural bolts.

Key Features

• 30 mm socket size for large fastener applications
• 12-point design allows more drive positions in confined spaces
• 1/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Alloy steel construction for strength and durability under high torque
• Chrome-plated finish for corrosion resistance and easy cleaning
• Meets AS4984A and ASME B107.110-2012 standards

Compatibility

Designed as a standard-fitment hand socket for use with any 1/2 inch drive ratchet, extension, or torque wrench following ASME B107 drive-tool specifications.

Installation Notes

This socket is intended for installation and removal of fasteners by qualified mechanics and maintenance technicians using hand tools. Always ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Do not use hand sockets with impact drivers unless the socket is impact-rated. Inspect the socket for cracks or wear before each use and remove from service if damage is found.
