## Summary description

Unior socket adapter 1/4" (6.35 mm) drive to 3/8" (9.5 mm) drive, 12-point configuration. Designed to adapt sockets and ratchets between different drive sizes, enabling use of 1/4" sockets on 3/8" tools or vice versa where compatible. Metal construction provides reliable torque transfer for maintenance, automotive and general mechanical work.

## Long description

Unior Socket Adapter 1/4" to 3/8" with a 12-point configuration enables compatibility between tools and sockets of different drive sizes. This adapter converts a 1/4" (6.35 mm) drive to a 3/8" (9.5 mm) drive or allows using 3/8" sockets on 1/4" drive tools where fittings permit. Manufactured from metal for durable torque transfer, it is intended for maintenance, automotive and general mechanical tasks that require flexible socket and ratchet combinations.
Advantages
The adapter’s 12-point geometry provides multiple engagement positions for easier alignment in tight spaces and reduces the need for precise indexing. Solid metal construction ensures reliable transmission of torque and resistance to wear under normal workshop use. Its compact form factor minimises added length between tool and socket, retaining access in confined areas while allowing cross-compatibility between common drive sizes.
Suitable for
Automotive repair and maintenance where mixed socket sets are used
General mechanical and assembly work requiring drive-size conversion
Service and fieldwork where carrying fewer ratchets and sockets is preferred
Home DIY projects that involve small-to-medium fasteners
Key specifications
Input drive size: 1/4" (6.35 mm)
Output drive size: 3/8" (9.5 mm)
Point configuration: 12-point
Material: metal construction for torque transfer
Form factor: compact adapter length to maintain access in confined spaces
How to use
Select the direction of adaptation required (use 1/4" socket on 3/8" drive or 3/8" socket on 1/4" drive where compatible). Firmly insert the adapter square into the ratchet or extension until it engages. Attach the desired socket to the opposite end and ensure the retention detent or friction fit is secure before applying torque. Use smooth, controlled force and avoid sudden impacts or excessive torque beyond the tool’s rating to prevent damage.
Usage recommendations
Use the adapter for occasional conversions between 1/4" and 3/8" drive tools and sockets; avoid applying torque that exceeds the smaller drive’s safe limits. Inspect the adapter and mating tool faces for wear before use and replace if deformation or rounding is observed.
