براغي رأس سداسية M20-2.5 × 130 مم | فئة 10.9 فولاذ بزنك أصفر | ملولبة جزئيًا (20 / عبوة)

The partially threaded design made aligning these with my machinery frame much easier than fully threaded bolts I've used before. The yellow zinc finish seems durable and the hex heads fit my socket perfectly without any rounding.

I needed a partially threaded bolt for a heavy equipment jig and these M20s fit the bill perfectly—the hex head gave my socket a solid bite without slipping. The yellow zinc finish seems consistent all around, and the 130mm length was just right for my application.

The zinc coating on these M20 bolts seems decent and should hold up fine in a dry shop environment. I used them to secure a heavy motor mount, and the 10.9 grade steel felt solid driving in with a socket. Only knocked off one star because the threading stops a bit shorter than I expected for a 130mm
