براغي ماكينات M4 × 40 مم | رأس مقبب مشقوق | فولاذ مطلي بالزنك (800 / عبوة)

The zinc plating on these screws is evenly applied and hasn't chipped even when I used a power driver on some panels. The slotted pan heads seat flush and the full 800 count means I've got plenty left for future projects.

The zinc plating on these screws is flawless and seems to resist rust really well. I used them to secure a metal electrical box to a frame, and the 40mm length was exactly what I needed for a clean fit.

I've been using these screws for mounting brackets in my workshop, and the 40mm length is exactly what I needed for thicker metal panels. The slotted drive seats well with a standard screwdriver, and the zinc coating has held up without any rust so far.
