Customer Reviews (4.6 / 5 · 5 reviews)

Owen ★★★★★

The hex socket drive grabbed perfectly on my torque wrench, and the black oxide coating kept rust off during a humid week in the shop. These M24 bolts held a jig steady under heavy load without any flex.

Aurora C. ★★★★★

Installed these in a critical fixture for our tooling line and the partially threaded length gave me just the right grip depth. The black oxide finish has a nice consistent sheen and the hex socket seated cleanly without any wobble; they feel properly rigid at M24 size.

Alexander W. ★★★★★

The black oxide finish on these M24 screws handled my jig assembly perfectly without any galling on the threads. The 12.9 alloy steel feels rock-solid, and the 350mm length gave me exactly the reach I needed for the fixture setup.
