Proto J5207MH 7mm 3/8 Drive 6-point Hand Socket

Product Description

The PROTO J5207MH is a 7 mm, 6-point hand socket designed for professional-grade fastener work in mechanical, industrial, and maintenance trades. Built to a standard length profile, it features a 3/8 inch drive and a chrome-plated finish that resists corrosion and makes cleanup straightforward on the job. The 6-point internal geometry delivers full-face contact on hex fasteners, reducing the risk of rounding during high-torque applications. This socket is a single-piece unit packaged individually and suits technicians who need reliable, correctly sized tooling without bulk quantities.

This socket fits into general mechanical service, HVAC equipment maintenance, plumbing fixture work, and light industrial assembly where 7 mm fasteners appear. The 3/8 inch drive pairs with standard ratchets, extensions, and breaker bars common in most field and shop tool kits. Its compact standard-length body allows access in moderately tight fastener locations without requiring a shallow or deep variation. Technicians in automotive, facilities maintenance, and equipment service will find this size relevant across a wide range of hardware.

Key Features

• 7 mm socket size for precise fit on metric hex fasteners
• 3/8 inch drive compatible with standard ratchets and extensions
• 6-point design maximizes contact surface and reduces fastener rounding
• Standard length profile suits general-access fastener locations
• Chrome-plated finish resists corrosion and simplifies surface cleaning
• Lightweight construction at 0.05 pounds for reduced hand fatigue

Compatibility

Designed as an OEM-style replacement or addition for professional hand tool sets using 3/8 inch drive sockets in standard metric sizes.

Installation Notes

Seat the socket fully onto the drive before applying torque to prevent slippage or fastener damage. Inspect the drive square and socket bore for wear or debris before each use. Never use a hand socket with an impact driver unless the socket is specifically impact-rated. Store in a dry location to preserve the chrome finish.
