براغي ماكينة M4 × 10 مم | رأس جبنة قيادة مشقوق | فولاذ مطلي بالزنك (1000/عبوة)

Opened the package and the thread cutting is so clean, every one of these M4 screws seated perfectly in my steel enclosure right out of the box. The slotted drive felt solid, no cam-out even with the cheese head shape.

The zinc plating on these M4 screws is nice and even, and they fit perfectly into my metal enclosure project without any stripping. A full bag of a thousand is exactly what I needed to finish the job.

Cheese head gave me a nice flat bite on the driver without slipping, and the slotted drive held up even when I torqued them into an aluminum panel. For a thousand screws at this price, the zinc finish seems solid so far.
