Customer Reviews (4.8 / 5 · 5 reviews)

Scarlett U. ★★★★★

Fit perfectly on my mini lathe jig — the black oxide finish seems strong enough to resist rust. Nice to have a full 200-count pack for future projects.

Ryan P. ★★★★★

Took a chance on these for a precision assembly and the black oxide finish is holding up perfectly against a bit of oil I use. Threads cut clean and the hex socket drove without any stripping.

Emma S. ★★★★★

Used a handful to secure a jig on my milling table and the black oxide finish held up well against cutting oil splatter. The threads cut cleanly into the tapped hole without any binding, exactly what I needed for a precision assembly.
