Socket wrench, Unior 3/8" drive, 11/16" (12-point), model 616930

Unior 3/8" drive socket, size 11/16" (12-point) is a metal hand tool designed to connect to standard 3/8" square drive ratchets and extensions. The 12-point profile enables engagement with 12- and 6-point fasteners and can fit slightly rounded heads while offering better access in confined or angled positions. This socket is intended for tightening and loosening nuts and bolts in automotive, mechanical and household repair tasks where a compact 12-point tool is required.

Advantages

The 12-point geometry provides multiple engagement positions for quicker alignment with fastener corners, reducing time spent positioning the tool. Manufactured from hardened alloy steel, the socket delivers wear resistance and dimensional stability under torque. The 3/8" drive interface ensures compatibility with a wide range of ratchets, torque wrenches and extensions used in light to medium duty applications. A slim wall profile improves reach in tight spaces compared with heavier impact-style sockets.

Suitable for

• Automotive maintenance and repairs (engine bays, brake and suspension work)
• General mechanical assembly and disassembly
• Household repairs and maintenance tasks
• Working in confined or angled access areas where multiple engagement positions help

Key specifications

• Drive size: 3/8" square drive
• Socket size: 11/16"
• Point profile: 12-point
• Material: hardened alloy steel (peened or heat-treated for strength)
• Finish: corrosion-resistant surface treatment
• Wall type: standard/slim wall for improved access

How to use

Attach the socket to a compatible 3/8" drive ratchet, breaker bar or extension by inserting the square drive into the socket until the retaining ball or detent engages. Position the socket over the fastener head, ensuring it seats fully on the flats or corners, then apply steady torque in the required direction to tighten or loosen. For torque-critical applications use an appropriate calibrated torque wrench with the socket. Avoid using cheater bars or excessive force beyond the tool's intended capacity to prevent damage.

Usage recommendations

Inspect the socket before use for visible wear or rounding; do not use a damaged socket on high-torque fasteners. For repetitive or high-torque tasks consider using appropriate powered tools or impact-rated sockets designed for those applications. Store sockets in a rack or organizer to prevent corrosion and to keep sizes readily accessible.
