Thomas ★★★★★

The 100° flat head sits flush perfectly on the aluminum brackets I’m mounting, and the trivalent zinc finish hasn’t shown a speck of rust after a few humid days in the garage. A full thousand pieces means I’ll be stocked for years, and every single one has threaded cleanly so far.

Henry ★★★★★

I needed a solid batch of flat head screws for mounting control panels, and these 1/4-20 machine screws fit perfectly with the 100° angle countersink. The trivalent zinc coating looks uniform and should hold up fine against minor corrosion in my garage projects.

Ellie F. ★★★★★

Bought a full box for a batch of panel fastening projects, and the trivalent zinc finish is holding up nicely even in my damp garage. The phillips drive grabbed cleanly without stripping on a dozen test holes. Solid value for the quantity.
