براغي ماكينة 3/8-16 × 3/4 بوصة | رأس مسطح مع شق قيادة | فولاذ مطلي بالزنك (600/عبوة)

The slotted drive on these flat head screws bites well with a standard screwdriver, and the zinc plating looks even and smooth across all 600 pieces. I used them to mount a steel enclosure to a frame and every one of them threaded clean without any stripped heads or burrs.

Packed 600 screws in a sturdy box, and every single one has a clean, consistent slot on the flat head. The zinc coating looks even and smooth, which should help prevent rust in my workshop environment.

These are exactly what I needed for a metal bracket project I was finishing up, and the zinc plating on the 600-pack looks like it'll hold up well against minor rust. The flat head sits flush in the countersunk holes, which made for a clean, professional-looking assembly.
