Ruby H. ★★★★★

The threads on this adapter are cleanly machined and seat without any wobble. Hooked up my 7/16" fitting to the 3/8" side in seconds, and it's held tight through a full afternoon of use. Exactly what I needed.

Victoria ★★★★★

This little adapter solved my problem perfectly—the threads are clean and screw on smoothly without any wobble. I’m using it to connect a different backing pad to my angle grinder, and so far it’s holding tight with no issues.

Zoe ★★★★★

Took a chance on this adapter since my old one stripped out, and the threads cut smoothly on both ends without any binding. It mates securely and solved my fitment issue perfectly.
