Customer Reviews (4.4 / 5 · 5 reviews)

Victoria ★★★★★

I’ve used these #4-40 fasteners on a few sheet-metal brackets now, and they set perfectly every time—no stripping, no wobble. The steel holds up well under a wrench, and the 200-count pack makes it easy to keep a stockpile on the bench.

Carter C. ★★★★★

The steel construction feels much sturdier than the aluminum ones I've used before, and they press into the sheet metal cleanly on the first try. Perfect for my general assembly jigs.

Miles ★★★★★

Just got these installed on a test bracket and the self-clinching action is spot-on—they seated flush with a solid pop, no distortion on the steel panel. The #4-40 threads are clean and consistent across all 200 pieces, which is exactly what I need for repetitive assembly work.
