Impact Socket Adapter 1/4 in to 3/8 in

This Westward 4PRJ2 adapter converts a 1/4 inch male hex drive into a 3/8 inch male square drive for impact applications. It measures 4 inches overall and features a black oxide finish. The tool is designed for use with impact drivers where a drive size change is required.

Impact drive limits

The adapter is rated for impact use but is not non-sparking and carries no insulation rating. It should not be used in explosive atmospheres or on live electrical circuits. Torque capacity is limited by the smaller 1/4 inch input drive, so excessive force can damage the hex shank or the fastener.

Installation and common issues

The hex shank inserts directly into a 1/4 inch impact driver chuck or quick-change holder, while the 3/8 inch square drive accepts standard impact sockets. A frequent problem is the hex shank rounding out under high torque, especially if the driver chuck is worn or the adapter is not fully seated. Ensure the socket locks securely on the square drive to prevent it from disengaging during operation.

Questions about this item

What drive sizes does this impact socket adapter connect?

The adapter has a 1/4 in male hex input and a 3/8 in male square output, letting you use 3/8 in impact sockets on a 1/4 in drive tool.

How does the 4 in overall length affect access in tight spots?

At 4 in long it adds a short reach between the tool and socket, which helps clear obstructions while keeping the assembly compact for confined work areas.

Is the black oxide finish rated for impact use on a regular basis?

Yes, the adapter is built for impact duty and the black oxide coating provides corrosion resistance during repeated high-torque applications.
