Proto J5530 Hand Socket 15/16 Inch 12-point 3/4 Drive

Product Description

The PROTO J5530 is a 15/16 inch, 12-point hand socket designed for 3/4 inch drive ratchets and breaker bars. Built from alloy steel with a chrome-plated finish, it delivers corrosion resistance and durability in demanding shop and field conditions. The standard-length profile measures 2 inches overall, making it suitable for a wide range of fastener access situations. Manufactured to ASME B107.110-2012 standards, this socket meets the dimensional and performance requirements expected by professional mechanics, millwrights, and maintenance technicians working with larger fasteners.

This socket is appropriate for both residential and commercial maintenance applications where 3/4 inch drive tooling is standard. It is well suited for heavy equipment service, industrial machinery maintenance, and structural fastener work. Trades including mechanical contractors, industrial maintenance crews, and fleet mechanics routinely rely on 3/4 inch drive sockets of this size when working on large bolted assemblies.

Installation Notes

Installation and removal of fasteners with this socket should be performed by qualified mechanics or maintenance technicians. Ensure the drive tool is fully seated before applying torque to prevent socket or fastener damage. Inspect the socket for cracks or wear before each use and remove from service if damage is found. This socket is not rated for impact driver use; use impact-rated sockets with pneumatic or electric impact tools.
