Proto J7210S Impact Socket 3/8 in Drive 5/16 in 8-point

Product Description

The PROTO J7210S is a 3/8 inch drive impact socket designed for use with pneumatic and electric impact wrenches in professional trade applications. Built from alloy steel, this 8-point socket measures 5/16 inch in size and 1 inch in overall length. Its compact profile makes it well-suited for fastening tasks in tight or confined spaces. The alloy steel construction provides the toughness required to handle the repeated shock loads generated by impact tools without cracking or deforming. It is intended for use by mechanics, HVAC technicians, electricians, plumbers, and other trade professionals who work with impact-driven fasteners on a regular basis.

This socket is appropriate for both residential and light commercial service work where 5/16 inch 8-point fasteners are encountered. The 3/8 inch drive size is a common standard on mid-range impact wrenches and ratchets used across multiple trades. Its short overall length of 1 inch suits flush or recessed fastener installations where a longer socket would not fit. This socket ships individually and is sold as a single unit.

Installation Notes

Install and remove this socket by hand before applying impact tool force to confirm proper seating on the fastener. Always power down or disconnect the impact tool before changing sockets. Inspect the socket for cracks or wear before each use, as damaged impact sockets should be removed from service immediately. Refer to applicable torque specifications for the fastener being driven, as the socket itself does not establish torque limits.
