Steven I. ★★★★★

I needed fully threaded M6 bolts for a tight assembly and the 40mm length was perfect. The hex head gave my socket a solid grip without slipping. For 300 pieces at this price, you can't beat the value.

Evelyn ★★★★★

The yellow zinc finish looks sharp and held up fine under the workbench lights, but what really sold me is how perfectly the threads cut in—every single one of the 300 seated cleanly without a single stripped one. These M6 bolts are exactly what my assembly line needed, and the hex heads grab the so

Kevin K. ★★★★★

Installed these on a heavy-duty jig that kept loosening; the Class 10.9 steel holds torque way better than standard bolts. The yellow zinc coating on all 300 pieces was consistent, which saved me from sorting out duds.
