Socket 3/8" to 13/16", 12-point, Unior (MPN 616932)

Unior 12-point socket adapts a 3/8" drive to a 13/16" working size, providing a compact solution for tasks that require a larger socket on standard 3/8" ratchets or extensions. The socket’s 12-point profile allows quicker alignment on hex fasteners and helps when access is limited, making it suitable for workshop, automotive and maintenance environments. It is a single-piece hand tool accessory designed to transfer torque reliably between the drive tool and the fastener.

Advantages

The 12-point geometry reduces the need for precise positioning, enabling faster engagement on 13/16" fasteners with fewer handle movements. Compatibility with 3/8" drive ratchets and extensions offers versatility without needing a larger drive tool. Constructed for mechanical use, the socket provides a secure fit on fasteners and durable performance for repeated tightening and loosening operations.

Suitable for

• Automotive repair and maintenance where 13/16" fasteners are present
• Mechanical assembly and disassembly tasks in workshops
• General maintenance and service work with limited access to fasteners

Key specifications

• Drive compatibility: 3/8" drive
• Socket size (working): 13/16"
• Point profile: 12-point for easier alignment
• Use type: hand tool accessory for ratchets and extensions
• Typical applications: automotive, mechanical, maintenance

How to use

Attach the socket to a compatible 3/8" drive ratchet or extension by pushing it onto the drive until it seats securely. Position the 12-point socket over the 13/16" fastener and rotate the ratchet to tighten or loosen as required. For best results, ensure the socket is fully engaged on the fastener before applying significant torque and avoid side loading that can damage tool or fastener faces.

Usage recommendations

Use with matched 3/8" drive ratchets or extensions and avoid excessive impact-style loading unless the socket is specifically rated for impact use. Inspect the socket and fastener for wear before use and replace if any deformation or cracking is evident.
