Customer Reviews (4.8 / 5 · 5 reviews)

Edward ★★★★★

Used these on a jig I was building and the 55mm length was exactly what I needed. The hex drive seated cleanly without any stripping, and the black oxide finish looks professional.

Henry ★★★★★

The black oxide finish on these M5s holds up far better than the zinc-plated ones I’ve used before, no staining after a full week in a damp shop. The 55mm length seated perfectly in my aluminum fixture, and the hex socket drive grabbed cleanly every time without stripping.

George ★★★★★

I needed longer screws for a jig I’m building, and these 55mm M5s were exactly right—threads cut cleanly into the tapped holes. The socket drive made them easy to install even in tight spots.
