Matthew P. ★★★★★

Had to swap out the original bolts on a jig I'm building, and these slid right in with no binding. The black oxide finish looks clean and the 12.9 alloy steel feels plenty sturdy for the load. Really glad I went with this length instead of the shorter ones.

Lily ★★★★★

Used several of these M18-2.5 x 300mm cap screws to hold a heavy jig plate together on my mill, and the partially threaded design made alignment a breeze. The black oxide finish looks sharp and seems to resist shop grime so far.

Hazel ★★★★☆

Needed a longer 300mm bolt for a jig I'm building, and the 12.9 grade gives me confidence it won't snap under load. Only minor thing is the black oxide coating had a tiny scuff on one of the heads, but the threads are clean and the hex drive seated perfectly.
