Customer Reviews (3.8 / 5 · 5 reviews)

Richard Z. ★★★★★

Bought these for some metal enclosure repairs and the zinc coating really resisted the shop moisture. The flat 82° head sits perfectly flush in the countersunk holes.

Lucy P. ★★★★☆

The slotted drive is easy to work with, and the 82° flat head sits nicely countersunk in my metal enclosure. Took off one star because the zinc finish is a bit duller than I expected, but they thread cleanly and held up fine so far.

Thomas Z. ★★★★☆

Got exactly the 4-40 x 3/8 size I needed for attaching small panels, and the flat 82° head sits flush nicely. The zinc plating looks even and should hold up fine indoors. Only gripe is the slotted drive wants a precise driver fit, but that’s standard for this style.
