Socket wrench Unior 3/8" drive 9/16" 12-point (MPN 616928)

Unior 3/8" drive 9/16" 12-point socket is a compact hand tool designed for use with 3/8" square drive ratchets and handles. The 12-point internal profile allows quicker alignment on fasteners compared with a 6-point design, making it practical for confined spaces and for repeated fitting and removal of nuts and bolts. Manufactured by Unior, this socket is intended for standard maintenance and repair jobs where a reliable, space-efficient socket is needed.

Advantages

The 12-point geometry provides easier engagement on hex fasteners and enables turning at smaller swing arcs, improving access in tight locations. Machined internal faces ensure secure contact with the fastener to reduce slipping. The 3/8" drive interface is compatible with a wide range of ratchets, extensions and adapters, offering versatility across automotive, machinery and general workshop toolsets.

Suitable for

• Automotive repairs and servicing where compact sockets are required
• Maintenance of machinery and equipment with standard hex fasteners
• Home workshop and general DIY tasks involving nuts and bolts

Key specifications

• Drive size: 3/8" square drive (compatible with standard 3/8" ratchets)
• Socket size: 9/16"
• Internal profile: 12-point for quicker alignment
• Material and finish: hardened steel with machined interior faces (material grade depends on manufacturer standards)

How to use

Select the 9/16" socket and attach it to a compatible 3/8" drive ratchet, extension or adapter. Fit the socket onto the hex fastener until it seats fully, then apply turning force using the ratchet handle. For loosening tight fasteners, apply steady force and use an appropriate extension or breaker bar if required. After use, wipe the socket clean and store it in a socket rail or organizer to prevent corrosion and loss.

Usage recommendations

Use the socket only with suitably sized fasteners and compatible 3/8" drive tools. Avoid using the socket with impact drivers unless it is specifically rated for impact use. Inspect the socket for wear or deformation before use and replace if damaged to maintain safe and reliable operation.
