Customer Reviews (4.8 / 5 · 5 reviews)

James Z. ★★★★★

I needed long bolts for a heavy jig build, and the 190mm length on these M18 screws saved me from stacking washers. The thermal black oxide coating gave them a nice, consistent finish that slipped right into place.

Madison P. ★★★★★

The thread engagement on these is perfect for a 190mm fastener — no wobble at all when torquing them down. The black oxide finish feels grippy and consistent across all ten pieces, which matters when you're seating them in a precision fixture.

Hannah T. ★★★★★

I was pleasantly surprised by how precisely these hex socket screws threaded into my jig setup — the black oxide finish gave them a nice, uniform look. The partial threading made alignment much easier without binding.
