Customer Reviews (4.8 / 5 · 5 reviews)

Robert F. ★★★★★

These things are beefy. I needed fully threaded bolts for a heavy equipment bracket and the class 8.8 steel holds up perfectly under load. The 40mm length was exactly what my design called for.

Sebastian ★★★★★

Hex head fit perfectly with my impact socket, and the fully threaded design made adjusting the stack height on a press frame simple. For the price, getting 30 of these class 8.8 bolts feels like solid value.

Violet ★★★★★

Used these on a heavy-duty conveyor guard repair at the plant—the hex head gave my socket wrench a solid grip, and the full threading held torque without stripping. They were exactly the 40mm length I needed, and the 8.8 steel feels plenty tough for the job.
