براغي ماكينة مقاس #4-40 × 7/8 بوصة | رأس مقبس مع شق دفع | نايلون (1000 / عبوة)

The pan head shape sits flush against the enclosure without any wobble, and the nylon threads grip cleanly without stripping. I’ve used about thirty of these today for a panel assembly and they’re holding up exactly as needed.

I was worried nylon would be too fragile, but these #4-40 screws held my control panel securely without stripping the threads during installation. The 7/8" length was just right for my enclosure project.

The slotted drive is easy to work with even when wearing gloves, and they’re light enough that a whole bag won’t weigh you down. I’ve already used a few dozen on an enclosure project and the nylon threads hold up nicely.
