Proto J4770TA 7/32 Inch 12-point Hand Socket 1/4 Drive

Product Description

The PROTO J4770TA is a 7/32 inch, 12-point hand socket designed for use with a 1/4 inch drive ratchet or extension. Built from alloy steel with a chrome-plated finish, it features a universal/flex socket type that allows for angled access in tight or awkward fastener locations. At 1-1/4 inches overall length and 0.04 pounds, it is a compact, lightweight tool suited for precision fastener work. It meets ASME B107.1 standards, confirming dimensional and performance compliance. Mechanics, HVAC technicians, electricians, and plumbers reach for this socket when working in confined spaces where a standard rigid socket cannot seat squarely on the fastener.

This socket is appropriate for residential and light commercial service work where small fasteners in restricted locations are common. Typical applications include panel work, equipment access covers, and component mounting hardware encountered during HVAC, electrical, and plumbing service calls. The universal/flex design makes it especially useful when the drive axis cannot align directly with the fastener axis, reducing the need for multiple adapter setups. It is sold individually and is compatible with standard 1/4 inch drive hand tools.

Installation Notes

This socket is installed and used by any trade professional working with hand tools on small fasteners. Always power down or de-energize equipment before accessing fasteners on electrical panels or HVAC components. Ensure the flex joint is fully seated on the fastener before applying torque to avoid rounding the fastener head. Do not use impact drivers with this hand socket.
