براغي ماكينة M6-1 × 20 مم | رأس مسطح بشق | فولاذ مطلي بالزنك (1,200/عبوة)

The zinc coating on these M6 screws gives me confidence they won't rust in my outdoor project. I used a dozen to secure a wooden sign, and the slotted drive bit into the steel nicely without stripping. For the price of this bulk pack, I'm set for years.

The flat head sits perfectly flush in my metal project, and the zinc coating looks clean. I used about 60 of these today without a single stripped head.

I needed a bulk pack of M6 machine screws for assembling some shelving units, and these 20mm flat heads with the slotted drive worked perfectly with my standard screwdriver. The zinc plating seems solid, and for the price getting 1,200 in a single package was exactly what I was looking for.
