Proto J7220HF Impact Socket 3/8 in Drive 5/8 in 6-point

Product Description

The PROTO J7220HF is a 6-point impact socket designed for use with 3/8 inch drive impact wrenches and rattle guns. Built from alloy steel, it accepts a 5/8 inch hex fastener and features a magnetic retention design to hold fasteners securely during installation and removal. The overall length measures 1-7/32 inches, making it suited for standard-depth fastener access. Licensed trades including electricians, HVAC technicians, and plumbers rely on this socket when impact torque is needed for equipment mounting hardware, panel fasteners, and mechanical connections.

The J7220HF fits into general mechanical and trade service applications wherever a 3/8 inch drive impact socket is required. Its compact 1-7/32 inch length suits confined fastener locations common in equipment bays, electrical enclosures, and mechanical rooms. The magnetic style assists single-handed fastener placement on overhead or awkward-angle work, reducing dropped hardware during service calls.

Designed as an OEM-style replacement or service socket for use with 3/8 inch drive impact tools requiring a 5/8 inch 6-point hex socket.

Installation Notes

Install and remove using a 3/8 inch drive impact wrench or breaker bar. Verify the socket is fully seated on the fastener before applying impact torque to avoid slippage or fastener damage. Do not use impact sockets on standard ratchets where torque exceeds the ratchet rating. Inspect for cracks or deformation before each use and replace if damaged.
