Proto J5530M 30mm 12-point 3/4 Drive Hand Socket

Product Description

The PROTO J5530M is a 30 mm, 12-point hand socket built for professional-grade fastener work. Manufactured from alloy steel with a chrome-plated finish, this standard-length socket fits a 3/4 inch drive and delivers the torque capacity needed for heavy-duty automotive, industrial, and mechanical applications. The 12-point design engages fastener flats at multiple positions, giving technicians more swing clearance in tight spaces. At 2-7/32 inches overall length, it meets ASME B107.110-2012 standards for dimensional accuracy and performance. Licensed tradespeople and experienced mechanics rely on this socket for consistent, repeatable fastener engagement on high-torque assemblies.

The J5530M is suited for use in automotive repair shops, fleet maintenance facilities, industrial plants, and heavy equipment service environments. The 3/4 inch drive pairing makes it appropriate for large-fastener work on transmissions, suspension components, heavy machinery, and structural assemblies. The 30 mm socket size is common in metric fastener applications across both automotive and industrial platforms. This socket is a single-piece, non-tethered tool intended for standard shop and field use where drop-prevention tethering is not required.

Installation Notes

This socket is installed by qualified mechanics and technicians as part of a 3/4 inch drive socket set. Ensure the socket is fully seated on the drive tool before applying torque. Inspect the socket and drive tool for wear or cracks before use on high-torque fasteners. Do not use impact drivers with this hand socket unless the tool is specifically rated for impact use.
