Proto J4708LM Deep Hand Socket 8 Mm 6-point 1/4 Drive

Product Description

The PROTO J4708LM is a deep hand socket designed for 1/4 inch drive ratchets and extensions. It fits an 8 mm fastener head and features a 6-point internal geometry, which distributes torque across the flats of the fastener rather than the corners. This reduces the risk of rounding hardware under load. The socket is machined from alloy steel and finished with a chrome plating for corrosion resistance. At 1-63/64 inches in overall length, the deep profile provides clearance for fasteners set below a surface or seated on extended studs. Licensed HVAC technicians, plumbers, electricians, and auto technicians keep this size in their drive sets for tight-access work.

This socket is suited for residential and light commercial service work where 8 mm fasteners are common, including equipment panels, motor mounts, bracket hardware, and electrical enclosure hardware. The 1/4 inch drive sizing makes it compatible with compact ratchets and flex-head tools used in confined spaces such as air handler cabinets, panel boxes, and plumbing access areas. It is sold individually and is appropriate for both bench work and in-field service calls.

Key Features

Compatibility

Designed for use with standard 1/4 inch drive ratchets, extensions, and torque wrenches accepting 1/4 inch drive square-drive tooling.

Installation Notes

This socket is installed by trade professionals as part of a standard 1/4 inch drive set. Confirm the fastener size before applying torque to avoid damaging hardware. Inspect the socket for cracks or wear before use, and retire any socket showing deformation of the drive square or internal points. No power tools should be used with hand-rated sockets unless the socket is explicitly rated for impact use.
