Proto J4705LM Deep Hand Socket 5 Mm 6-point

Product Description

The PROTO J4705LM is a deep hand socket designed for professional fastener work requiring extended reach. Built to a 5 mm socket size with a 1/4 inch drive and a 6-point internal geometry, it delivers firm, even torque transfer to hex fasteners while reducing the risk of rounding. The chrome-plated finish resists corrosion and makes the socket easy to clean after use in greasy or dirty environments. This socket is suited for mechanics, maintenance technicians, and trade professionals who need reliable hand-tool performance on metric fasteners in confined or deep-set applications.

The J4705LM is used wherever a standard-depth socket cannot reach the fastener — recessed bolts, deep-well fastener pockets, and assemblies where a nut sits below a surrounding surface. Its compact 1/4 inch drive makes it compatible with standard 1/4 inch drive ratchets, extensions, and adapters common in HVAC, plumbing, electrical, and general mechanical service work. The 6-point design is preferred over 12-point sockets in professional applications because it contacts the flat faces of the fastener rather than the corners, reducing cam-out under high torque.

Key Features

• 5 mm socket size for metric fastener applications
• 1/4 inch drive fits standard ratchets, T-handles, and extensions
• 6-point geometry contacts fastener flats for reduced rounding
• Deep length reaches recessed or below-surface fasteners
• Chrome-plated finish provides corrosion resistance and easy cleaning

Compatibility

Designed for use with standard 1/4 inch drive ratchets, extensions, and drive tools. Fits 5 mm hex fasteners in deep or recessed installations across a wide range of mechanical, electrical, and plumbing service applications.

Installation Notes

Install and remove with a properly rated 1/4 inch drive ratchet or T-handle. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding the fastener head. Do not use impact drivers with hand sockets rated for hand-tool use only. Keep the socket and drive tool clean and free of debris for consistent engagement.
