Proto J4709LM Deep Hand Socket 9 Mm 6-point 1/4 Drive

Product Description

The PROTO J4709LM is a deep hand socket designed for professional hand-tool use in mechanical, HVAC, plumbing, and electrical service work. Built to a 9 mm socket size with a 1/4 inch drive and 6-point geometry, this socket delivers solid contact across flat fastener faces, reducing the risk of rounding corners under torque. The chrome-plated finish resists corrosion and makes for easy cleaning in the field. At 0.06 pounds, it is light enough for tight-access work without sacrificing the grip and wall strength expected from a professional-grade socket. Installers and service techs reach for this size frequently when working on equipment panels, junction boxes, and mechanical assemblies.

This deep socket is suited for trade applications where standard-depth sockets cannot fully seat over fasteners with extended threads or where reach into recessed bolt locations is required. It is appropriate for residential and light commercial service work across HVAC, electrical, and plumbing disciplines. The 1/4 inch drive sizing makes it compatible with compact ratchets and extension bars commonly found in service technician kits.

Installation Notes

Inspect the socket for cracks or wear before each use. Power down or de-energize any equipment before using hand tools in proximity to live electrical components. Do not use hand sockets with impact drivers unless the socket is specifically rated for impact use. Follow applicable workplace safety codes when performing fastener work on pressurized or energized systems.
