## Summary description

Unior socket adapter 3/8" to 5/16" (model 616924) is a 12-point tool adapter designed to connect a 3/8" drive ratchet or handle to 5/16" sockets. It provides secure engagement with 12-point socket profile for machine bolts and fasteners. Suitable for general mechanical and maintenance tasks where a smaller 5/16" socket must be used with a 3/8" drive.

## Long description

Unior socket adapter 3/8" to 5/16" model 616924 is a compact 12-point adapter that lets you use 5/16" sockets with 3/8" drive ratchets and handles. The adapter provides a close fit and positive engagement with 12-point sockets, making it suitable for machine bolts and fasteners where a finer contact geometry is required. Constructed for standard workshop and maintenance work, the adapter is intended to bridge drive size differences while preserving socket functionality.
Advantages
The 12-point profile ensures reliable engagement with 5/16" sockets and reduces the chance of rounding fastener corners. Its compact form factor allows better access in confined spaces compared with larger adapters, and the precision-machined drive faces promote secure coupling to both the 3/8" drive and the 5/16" socket. The adapter is compatible with common ratchets and handles designed for a 3/8" square drive.
Suitable for
 General mechanical and automotive maintenance where 5/16" fasteners are present
 Workshop repair tasks requiring use of 5/16" sockets with 3/8" drive tools
 Maintenance of machinery and equipment with machine bolts and multi-point fasteners
Key specifications
 Drive conversion: 3/8" square drive to 5/16" square socket
 Socket profile: 12-point
 Intended use: manual ratchet and handle operation
 Form factor: compact adapter for constrained access
How to use
Select the 5/16" socket required for the task and press it onto the adapter's 5/16" end until it seats fully. Insert the adapter's 3/8" square end into the ratchet or handle until it locks or engages. Apply torque through the ratchet or handle as required for the fastener, keeping alignment to avoid side loads. After use, remove the adapter from the socket by pulling them apart and store in a tool tray or holder to prevent loss.
Usage recommendations
Use the adapter for hand-operated ratchets and handles only; avoid impact tools or excessive torque beyond the socket and fastener ratings. Keep contacting faces clean and free of burrs to ensure proper engagement and prevent premature wear.
