Customer Reviews (4.2 / 5 · 5 reviews)

Riley J. ★★★★★

Installed these in a jig fixture yesterday, and the nylon patch held tight even with vibration from the mill. The partial threading made alignment easier than I expected.

Ellie ★★★★★

The black oxide finish shed grime nicely during a week of jig assembly, and the nylon patch held fast without any thread locker. Fit was spot-on through the partial threads, exactly what my fixture needed.

Isabella F. ★★★★☆

The partially threaded design worked perfectly for securing a bushing on my tooling setup without extra spacers. The nylon patch held firm after a couple of test runs, though I wish the package included a few more screws for the price.
