Proto J77517MP Impact Socket 3/8 in Drive 17mm 12-pt

Product Description

The PROTO J77517MP is a 12-point impact socket designed for 3/8 inch drive impact wrenches and ratchets. Built from alloy steel, it is engineered to handle the high-torque demands of impact-driven fastening and removal in professional trade environments. The socket measures 2-3/32 inches overall length and fits a 17mm fastener. Its universal style makes it a practical addition to any mechanic, HVAC tech, plumber, or electrician's drive set where metric fasteners are common.

This socket is suited for use in automotive, mechanical, HVAC, plumbing, and electrical service applications where 17mm metric fasteners are encountered. The 3/8 inch drive size covers a broad range of mid-torque tasks, from panel and equipment assembly to component removal. The 12-point geometry allows engagement at multiple angles, which is useful in tight or awkward access situations common in field service work.

Installation Notes

This socket is installed by licensed mechanics, HVAC technicians, plumbers, electricians, and other trade professionals. Always verify the drive size of your impact tool matches the 3/8 inch drive of this socket before use. Inspect the socket for cracks or wear before each use, and do not use hand-socket tools in place of impact-rated sockets on impact wrenches. Use appropriate personal protective equipment when operating impact tools.
