Richard ★★★★★

Opening up the box, I was glad to see the zinc plating is even and clean across all 200 pieces, no rust spots or scratches anywhere. The hex heads fit a standard socket perfectly, and the 85mm length with partial threads worked great for bolting two steel plates together without the threads chewing

Ruby ★★★★★

The partially threaded shaft made these perfect for securing a clamping block while leaving room for adjustment. Threads were clean and the zinc coating looks even across all 200 pieces.

Aurora ★★★★★

Used these on a jig fixture that gets constant vibration, and the zinc plating still looks fresh after a week of use. The partial threading made alignment much easier than fully threaded bolts in tight spaces.
