براغي رأس سداسي M20-2.5 × 140 مم | فئة 8.8 فولاذ عادي | خيط جزئي (10 / عبوة)

The partially threaded design grabbed perfectly when I torqued them into the equipment frame, and the hex heads held the socket without slipping. Class 8.8 steel feels solid for the price, and the ten-pack came well organized.

Had to crank these down pretty hard with a wrench, and the hex head held up without stripping. The 8.8 steel feels solid for a heavy machinery repair I was doing.

The partial threading made these perfect for a jig I was building—the smooth shank section really helps with alignment. They torqued down evenly with a socket wrench without any stripping, which I appreciated. My first batch of parts is holding solid so far.
