براغي رأس سداسي M6-1 × 40 مم | فئة 8.8 فولاذ زنك أصفر | ملولبة بالكامل (300/عبوة)

Used these to secure some heavy brackets in my workshop, and the hex head made torquing them down with a socket effortless. The yellow zinc coating looks clean and seems like it will hold up well against moisture.

The 40mm length is spot on for my engine mount brackets, and the zinc coating seems thick enough to resist rust. They seated smoothly with a socket, which saved me a lot of time on a repetitive job.

Good threads, the class 8.8 steel feels solid and the yellow zinc coating looks like it'll resist rust well for indoor equipment. One minor thing: a couple screws had slightly uneven plating, but nothing that affects function.
