Proto J5215MN 12-point Hand Socket 15 Mm 3/8 Drive

Product Description

The PROTO J5215MN is a 15 mm, 12-point intermediate hand socket built for professional hand-tool use in trade and industrial environments. Manufactured from steel with a polished finish, this socket features a 3/8 inch drive and meets ASME B107.21 standards. The 12-point design provides multiple engagement positions, which is useful in confined spaces where swing arc is limited. At 1.78 inches in overall length and weighing 0.148 pounds, it fits into a standard socket set without adding bulk. Licensed mechanics, maintenance technicians, and service professionals who rely on hand tools for metric fastener work will find this a dependable daily-use socket.

This socket is suited for general mechanical and maintenance applications where a 15 mm metric fastener requires hand-driven torque. Typical scenarios include automotive service, equipment maintenance, and industrial assembly work. The 3/8 inch drive is a common intermediate size that bridges light-duty 1/4 inch and heavier 1/2 inch drive setups, making this socket a practical choice for mid-range torque applications. It is sold individually and is not tether capable, so it is not rated for working-at-height drop-prevention programs.

Key Features

• 15 mm socket size for metric fastener applications
• 12-point configuration allows engagement every 30 degrees, useful in tight spaces
• 3/8 inch drive fits standard ratchets, extensions, and breaker bars
• Polished steel construction meets ASME B107.21 standards
• Standard length profile at 1.78 inches overall
• Backed by a lifetime warranty

Compatibility

Designed as a standard OEM-style replacement or addition to 3/8 inch drive hand socket sets used in metric fastener service applications.

Installation Notes

Installation is performed by hand-tool mechanics and maintenance technicians using standard 3/8 inch drive ratchets or breaker bars. Always ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Disconnect power, lock out energy sources, or shut off equipment as required before accessing fasteners on machinery or electrical enclosures. This socket is not tether capable and should not be used in overhead or elevated work environments where drop hazards exist.
