براغي ماكينة #4-40 × 1-1/8" | رأس بانة فيليبس | فولاذ مطلي بالزنك الثلاثي (2000 / عبوة)

Needed a solid batch of small fasteners for metal enclosures and these #4-40s are exactly what I hoped for. The trivalent zinc finish looks clean and uniform, and the phillips heads bit perfectly without stripping. 2000 pieces in one box means I won't be running out anytime soon.

Got these for mounting some small control panels, and the 1-1/8" length was exactly what I needed to go through the bracket and into the standoff. The Phillips drive bit seated nicely without camming out, even when I torqued a few down with an impact driver.

The trivalent zinc finish on these #4-40 screws seems to be holding up well, no rust after a few weeks in a semi-damp basement. The Phillips drive grabs nicely without cam-out, and the 2000-count box is way more than I needed but the price was right.
