براغي ماكينة 1/4-20 × 1-1/2" | رأس مستدير مع شق قيادة | فولاذ مطلي بالزنك (900 / عبوة)

Picked up a pack for securing metal panels in a workshop project, and the zinc plating on these screws is nice and uniform. The slotted drive works perfectly with my old screwdriver, and the 1-1/2" length gave just the right bite into the frame. They held up well without any stripping.

Used a bunch to mount some steel enclosure panels, and the slotted round head seated nicely without stripping. The zinc coating looks uniform and seems like it'll hold up fine in my dry shop.

Bought the 900-pack for a shop project and the zinc plating is even and clean, no burrs on the threads right out of the box. These bit into the steel panel holes without any wobble, and the slotted heads take a standard screwdriver perfectly. For the price per piece, it’s hard to beat.
