براغي رأس سداسية M20-2.5 × 180 مم | فئة 10.9 فولاذ مطلي بالزنك الأصفر | ملولبة جزئيًا (10/عبوة)

The partially threaded design made aligning them in heavy machinery a breeze, and the yellow zinc finish held up well against a little moisture in the shop. They threaded smoothly the whole way down.

Used a socket to torque these down on a press frame, and the partial threading made alignment a breeze. The 10.9 rating gives me confidence they’ll hold up under heavy use.

Got these for a heavy equipment repair job I was dreading, and the partially threaded shaft made alignment so much easier than fully threaded bolts. The hex head grabbed perfectly with my socket, and the yellow zinc finish seems solid enough to resist a few seasons of shop grime.
