Customer Reviews (5.0 / 5 · 5 reviews)

Aurora ★★★★★

Used these to mount a heavy-duty workbench frame and the partial threading made alignment much easier. Grade 5 steel feels solid, and the hex heads bit into my socket without slipping.

Julian ★★★★★

The yellow zinc finish has held up well after several days of use on my milling machine, and the partial threading makes alignment much easier compared to fully threaded bolts.

Zoe E. ★★★★★

These bolts threaded smoothly into my tractor's 3-point hitch bracket, and the yellow zinc coating looks like it'll hold up well against moisture. The partially threaded design gave me just the right grip length for a solid connection.
