M12-1.75 X 130mm 六角頭螺絲 | 8.8級鋼黃鋅 | 部分螺紋 (25個/包)

Used these on a heavy equipment jig I’m building, and the partial threading made alignment much easier than fully threaded bolts. The zinc coating looks consistent and should hold up fine in the shop.

I stripped the packaging and grabbed one for a test fit on the assembly jig, and the 130mm length with the partial threads lined up exactly where I needed them. The class 8.8 yellow zinc finish looks clean and the hex head grabbed a socket without any play, so these are solid for the machine build I

The partial threading made installation into my equipment frame much easier, and the hex head grabbed my socket perfectly without slipping. These feel solid for the price, no stripped heads during torquing.
