براغي ماكينة #4-40 × 1-1/2 بوصة | رأس مقبس مع شق | نايلون (200 / عبوة)

Installing these in a tight panel was a breeze because the nylon material let the screw seat perfectly without any galling. The slotted drive caught the bit firmly, too. Exactly what I needed for a non-conductive fastening job.

I was worried about stripping the threads in a plastic mount, but these nylon screws threaded perfectly and held firm. The 1-1/2 inch length was exactly what I needed for that panel.

My radio project needed nylon hardware to prevent short circuits, and these #4-40 screws fit perfectly through the panel holes. The slotted pan heads are easy to tighten by hand without stripping, and the 1½-inch length gave just enough grip for my metal enclosure.
