Victoria ★★★★★

The precision-ground shoulder on these screws made them perfect for a bearing surface I was building—they spin smoothly with zero wobble. I used them as axle pivots on a small cart, and the stainless finish hasn't shown a speck of rust yet.

Kevin ★★★★★

Installed these as pivot pins in a jig I built and the stainless finish looks great. The hex drive seated perfectly, no wobble at all during tightening.

Joshua ★★★★★

The shoulder on these screws is machined so smoothly they spin like a proper axle in my jig. Used a couple as bearing surfaces for a small rotary tool, and the 18/8 stainless feels solid enough for repeated use.
