Emily K. ★★★★★

Needed a long bolt for a custom jig and these 170mm screws fit the bill perfectly. The hex socket drive made tightening easy even in tight spaces, and the 12.9 alloy steel feels incredibly strong.

Amelia ★★★★★

For a critical jig I was machining, these 170mm bolts fit flawlessly and the black oxide coating held up perfectly under clamping pressure. The hex drive seated cleanly without any stripping, and the partial threading made alignment a breeze.

Hannah ★★★★★

Just finished a tricky fixture build and these M12x170mm screws fit perfectly with the partially threaded design giving just the right grip. The black oxide coating seems durable and the hex socket drove smoothly without any cam-out. Exactly what I needed for heavy-duty jig work.
