Ryan ★★★★★

Bought these to fix the column mount on my bench mill after the original bolts stripped, and they threaded in cleanly with no fuss. The 40mm length sat perfectly in the hole and the hex head gave me plenty of grip with a standard wrench.

Ellie K. ★★★★★

Used these M10x40 hex heads to remount the column on my mill, and they threaded in perfectly with no wobble. The hardened steel held up well when torquing down. Exactly what the machine needed.

Sofia ★★★★★

Ordered a few of these to replace worn ones on my mill’s column mount, and the M10x40 length is spot on for the base—threads cut cleanly and seated without any binding. They’re solid enough that I torqued them down and haven’t felt any shift since.
