Proto J4715LM-OLD Deep Hand Socket 15mm 1/4 Drive

Product Description

The PROTO J4715LM-OLD is a deep hand socket designed for 1/4 inch drive ratchets and breaker bars. It accepts a 15mm fastener and features a 6-point internal profile, which maximizes contact area on hex fasteners and reduces the risk of rounding. Constructed from alloy steel with a chrome finish, this socket is built for repeated use in professional hand-tool applications. The deep-length design provides clearance for extended studs, recessed fasteners, and protruding threads where a standard-depth socket would bottom out before seating fully on the fastener.

This socket is suited for automotive, mechanical, and light industrial maintenance work where a 15mm deep socket on a 1/4 inch drive is required. The compact 1/4 inch drive makes it practical for confined spaces and lower-torque fasteners such as interior trim hardware, sensor brackets, small engine components, and instrument panel work. It meets ASME B107.5M standards, confirming dimensional and performance compliance for professional-grade hand tools.

Key Features

• 15mm socket size for metric fastener applications
• 1/4 inch drive compatible with standard ratchets, extensions, and adapters
• 6-point profile reduces fastener rounding versus 12-point designs
• Deep-length body clears extended studs and recessed fasteners
• Alloy steel construction with chrome finish for corrosion resistance and durability
• Meets ASME B107.5M dimensional and performance standards
• Limited lifetime warranty

Compatibility

Designed as an OEM-style replacement and standard fitment for 1/4 inch drive socket sets requiring a deep 15mm 6-point socket.

Installation Notes

This socket is intended for use by mechanics and maintenance technicians working with 1/4 inch drive hand tools. Ensure the socket is fully seated on the fastener and the drive tang is fully engaged in the ratchet or extension before applying torque. Do not use hand sockets with impact drivers or impact wrenches, as hand-rated sockets are not designed for the shock loads produced by pneumatic or electric impact tools. Inspect the socket for cracks or deformation before each use and remove from service if wear is detected.
