براغي آلية #4-40 × 3/4 بوصة | رأس مقبس مع شق | نحاس (600/عبوة)

I was pleasantly surprised by the consistent threading on these brass screws—every one of the 600 fit perfectly into my pre-tapped holes without any binding. The pan head profile sits flush against the panel, and the slotted drive gives me solid control when tightening with a screwdriver.

The brass finish looks sharp on my enclosure, and the slotted heads sit flush without any wobble when torqued down. I’ve used about forty so far and haven’t hit a single stripped thread, which is more than I can say for cheaper steel screws.

The slotted drive is crisp and the pan head sits flush without stripping. These 600 brass screws are consistent and fit perfectly for small panel work.
