3/8" Drive Impact Adapter Set

The Westward 4PRF9 set provides six black-oxide steel adapters and extensions for 3/8-inch drive impact tools. It covers output drive sizes of 1/4-inch, 3/8-inch and 1/2-inch with male square outputs. The female square input fits standard 3/8-inch impact guns. Overall lengths range from 1 1/4 inches to 5 29/32 inches for reach and clearance.

Upgrading From Basic Adapters

This kit replaces loose or mismatched single adapters that limit drive-size changes on the job. The jump is worth it when a technician regularly switches between 1/4-inch, 3/8-inch and 1/2-inch sockets on one impact wrench. It also removes the need to hunt for individual extensions in multiple lengths.

Build Fit And Clearance

The black-oxide finish resists corrosion in shop environments. The set needs a 3/8-inch drive impact wrench and compatible impact sockets to function. It frees up toolbox space by consolidating six drive configurations into one organised package. California Proposition 65 warnings apply to this product.

Questions about this item

What drive sizes do the 3/8" input adapters convert to?

The set includes adapters with 1/4", 3/8", and 1/2" square male output drives.

How do you secure the adapters to an impact gun?

Use a locking pin or retention ring on the 3/8" female square drive; the step often missed is seating the pin fully into the groove.

When should the black oxide finish be touched up?

Reapply a light oil coat when the surface shows bare steel to maintain corrosion resistance.
