Customer Reviews (4.6 / 5 · 5 reviews)

Leo ★★★★★

Drove these into a steel fixture with an impact driver and the hex heads seated perfectly every time—no cam-out at all. The yellow zinc finish has held up through a week of shop use without a speck of rust. For a full box of 900, the price per screw is hard to beat.

Penelope Y. ★★★★★

The partial threading on these 1/4-20s grabbed just right when I torqued down a jig base—no stripping, and the yellow zinc coating looks clean against the steel. For a box of 900, the consistency in thread pitch across the whole batch was impressive.

Emma A. ★★★★★

Used these on a press repair and the yellow zinc finish is holding up well in a slightly humid shop. The hex head took a socket nicely with no rounding, and the partial threading made alignment in the bracket much easier than a fully threaded bolt would have.
