Proto J5206M 6mm 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5206M is a 6 mm, 12-point hand socket designed for 3/8-inch drive ratchets and extensions. Built from alloy steel with a chrome finish, this socket delivers the corrosion resistance and surface hardness that working technicians expect from a tool in daily rotation. At 1-3/32 inches in overall length, it fits into standard-depth fastener applications without adding unnecessary bulk. This socket meets ASME B107.5 standards, confirming dimensional accuracy and load performance. It is a practical, single-unit tool for mechanics, HVAC technicians, plumbers, and electricians who need a reliable metric socket for panel work, equipment service, and general mechanical assembly.

The J5206M is suited for residential and commercial service environments where 6 mm metric fasteners appear on equipment panels, motor mounts, bracket hardware, and control assemblies. The 12-point design allows engagement at more positions than a 6-point socket, which is useful in tight quarters where full ratchet swing is limited. This socket is appropriate for hand-tool use with 3/8-inch drive ratchets, torque wrenches, and breaker bars in both shop and field settings.

Key Features

• 6 mm socket size for common metric fasteners in equipment and panel work
• 12-point configuration allows more engagement positions in restricted access areas
• 3/8-inch drive compatible with standard ratchets, torque wrenches, and extensions
• Alloy steel construction for strength under normal hand-tool torque loads
• Chrome finish provides corrosion resistance and easy surface cleaning
• Meets ASME B107.5 standards for hand socket dimensional and performance requirements

Compatibility

Designed for use with 3/8-inch drive hand tools including ratchets, torque wrenches, breaker bars, and standard extension bars.

Installation Notes

Install and remove fasteners with the drive tool fully seated on the socket to prevent rounding. Confirm the socket is fully engaged on the fastener head before applying torque. Do not use hand sockets with impact drivers or air tools unless the socket is rated for impact use. Inspect the socket for cracks or deformation before each use and replace if wear is visible.
