براغي ماكينة 1/4-20 × 1-3/4" | رأس بان مع فيليبس | فولاذ مطلي بالزنك (1000 / عبوة)

I needed a bulk box of quality fasteners for mounting electrical panels, and these 1/4-20 x 1-3/4" machine screws fit perfectly. The Phillips drive grabbed well without stripping, and the zinc plating has held up nicely in my metal shop environment.

The threads on these machined screws are very consistent, so they drove into my pre-tapped holes without any binding. The zinc coating seems evenly applied, and you get a full 1,000 pieces.

Ordered these for a metal enclosure project and the zinc plating looks even and clean right out of the box. The phillips heads bit in without stripping, and at 1-3/4" they’ve got plenty of bite for thicker panels. A thousand screws in one package means I won’t need to reorder for a long time.
