Zoe X. ★★★★★

Used these to mount a vice to my workbench, and the unthreaded grip section lined up perfectly through the table thickness. The 18/8 stainless finish cleaned up nicely with a quick wipe, and the hex heads held firm under heavy torque.

Ellie ★★★★★

I needed a partially threaded fastener for a jig I was building, and the unthreaded grip length on these cleaned up the fit perfectly. The 18/8 stainless steel heads also held up well under my torque wrench without stripping.

Henry ★★★★★

These bolts are perfect for mounting a vice to my workbench; the partial threading gives just the right grip length for a solid hold. The stainless steel feels durable and corrosion-resistant, exactly what I needed for a workshop setup.
