Proto J5277HAM 14mm 6-point 3/8 Drive Hand Socket

Product Description

The PROTO J5277HAM is a 14 mm, 6-point hand socket designed for professional-grade fastener work in mechanical, industrial, and trade service environments. Built from alloy steel with a chrome-plated finish, this socket delivers reliable corrosion resistance and a clean grip surface for everyday use. It fits a standard 3/8 inch drive ratchet or extension and measures 1-7/8 inches in overall length. The 6-point geometry reduces the risk of fastener rounding compared to 12-point designs, making it a preferred choice for high-torque applications. Licensed technicians and professional mechanics specify this socket for engine work, equipment servicing, and general mechanical maintenance.

This socket is suited for use in automotive, heavy equipment, HVAC, and light industrial service settings where a 14 mm metric fastener is encountered. It is appropriate for both shop bench work and field service where a 3/8 inch drive tool set is the standard. The compact 1-7/8 inch length fits into moderately tight clearances without requiring a deep-well socket. This is a standard hand-use socket and is not tether capable, making it appropriate for conventional ground-level service rather than elevated or overhead work-at-height environments.

Key Features

• 14 mm socket size fits standard metric fasteners encountered in automotive and mechanical service
• 6-point contact geometry reduces fastener rounding under high torque
• 3/8 inch drive fits common ratchets, extensions, and drive tools
• Alloy steel construction provides strength and durability under repeated use
• Chrome-plated finish resists corrosion and simplifies cleaning
• Meets ASME B107.5M standards for hand socket dimensions and performance

Compatibility

Designed as an OEM-style hand socket compatible with standard 3/8 inch drive ratchets, breaker bars, torque wrenches, and extensions. Fits any tool accepting a 3/8 inch square drive and a 14 mm metric fastener application.

Installation Notes

Installation and removal of fasteners should be performed by a qualified mechanic or service technician familiar with the associated equipment. Disengage power, lock out machinery, and relieve any stored mechanical energy before beginning fastener service. Do not use hand sockets with impact drivers unless the socket is rated for impact use. Inspect the socket for cracks or wear before each use and replace if any deformation is visible.
