## Long description

Jonnesway S16H3814 is a socket adapter that converts a 3/8" female drive to a 1/4" male drive, allowing the use of 1/4" sockets on tools with a 3/8" drive. The adapter is compatible with ratchets, torque wrenches and many impact tools, offering a compact and straightforward solution for adapting drive sizes in workshop and mobile repair environments.
Advantages
The adapter provides a reliable mechanical connection between different drive sizes without altering the tool or socket. Its compact construction minimises added length and maintains access in confined spaces. The reduction is simple to fit and remove, enabling fast changes between socket sizes and preserving the functionality of existing 3/8" tools when smaller sockets are required.
Suitable for
Using 1/4" sockets with 3/8" ratchets and wrenches
Mobile repair and field service where tool flexibility is needed
Workshop tasks requiring occasional use of smaller sockets
Tight or confined spaces where a short adapter is advantageous
Key specifications
Drive conversion: 3/8" (female) to 1/4" (male)
Intended tool compatibility: ratchets, torque wrenches, impact tools
Construction: compact, single-piece adapter designed for mechanical drive compatibility
Primary use: reduction adapter for socket fitting versatility
How to use
Attach the adapter by inserting the 1/4" male end into the 1/4" socket and then fit the 3/8" female end onto the 3/8" drive of the tool. Ensure the retaining mechanism of the tool or socket engages properly before applying torque. Remove the adapter by reversing the process, taking care to relieve any load on the fastener first. Use appropriate safety precautions when working with powered or high-torque tools.
Usage recommendations
Use the adapter for hand-operated and moderate-torque applications. For precision torque control or high-impact, heavy-duty tasks, confirm compatibility and consider using a dedicated drive or a purpose-made adapter rated for impact use.
