براغي آلية مقاس #4-40 × 5/16 بوصة | رأس مقلاة مع محرك مشقوق | فولاذ مقاوم للصدأ 18/8 (1600 / عبوة)

Finally, a bulk pack of #4-40 screws that are actually all the same length—no frustrating random shorties mixed in. The slotted pan head really bites down nicely into the aluminum enclosure I was mounting, and stainless steel means zero rust worries.

I needed a large batch of small screws for several enclosures, and these pan heads seated perfectly without stripping. The slotted drive worked fine with a standard screwdriver, and the stainless finish gives me confidence they won't rust outdoors.

The 18/8 stainless steel finish on these screws is noticeably smooth and consistent, which makes them a perfect match for the metal enclosures I'm working on. The pan head sits flush without catching on anything, and having 1600 in one box means I won't run out mid-project.
