Robert ★★★★★

Full thread engagement all the way along the shank, and the black oxide finish wiped clean with just a rag after a day of clamping fixtures. I've used cheaper 10.9s that stripped the hex socket on the second use, but these 12.9s held torque without a hint of rounding.

Ella Q. ★★★★★

The hex drive bit seated perfectly without any stripping, and the black oxide finish on these M8 bolts looks much more rugged in person. I used them to mount a jig plate on my mill table, and the 12.9 grade steel feels rock-solid under torque.

Samuel D. ★★★★★

Used these to secure a heavy-duty fixture on a milling table, and the 12.9 grade alloy steel held torque perfectly without any stripping. The black oxide finish also adds a nice, corrosion-resistant touch for shop use.
