Proto J5270HAM Hand Socket 7mm 6-point 3/8 Drive

Product Description

The PROTO J5270HAM is a 7 mm, 6-point hand socket designed for 3/8 inch drive ratchets and extensions. Machined from alloy steel with a chrome-plated finish, it delivers corrosion resistance and a clean surface that stands up to regular shop use. The 6-point geometry grips fastener flats squarely, reducing the risk of rounding under load. Overall length is 1-49/64 inches, making it suitable for standard-depth fastener access. This socket meets ASME B107.5M standards and is intended for professional hand-tool use by mechanics, millwrights, and maintenance technicians working with metric fasteners.

This socket fits common metric fastener applications found in automotive, industrial, and mechanical maintenance environments. The 7 mm size is frequently used on smaller fasteners in engine accessories, electrical components, and light equipment. It pairs with any standard 3/8 inch drive ratchet, breaker bar, or torque wrench. This is a single-piece socket suitable for both bench work and in-vehicle or in-equipment service where a compact, reliable 7 mm solution is needed.

Installation Notes

Install and remove using a 3/8 inch drive ratchet or torque wrench per the fastener manufacturer's torque specification. Ensure the socket is fully seated on the fastener before applying force to avoid slippage or rounding. Inspect the socket and drive square for wear or cracking before each use, and do not use a socket that shows visible damage. Chrome-finished sockets are intended for hand-tool use only and should not be used with impact drivers.
