براغي رأس سداسي M6-1 × 80mm | فئة 10.9 فولاذ أصفر زنك | جزئي الخيط (200/عبوة)

I needed strong bolts for a heavy machinery repair, and these M6-1 x 80mm cap screws with the class 10.9 rating held up perfectly under torque. The partially threaded design made alignment much easier than fully threaded options I've used before.

The yellow zinc finish looks sharp and held up fine during an outdoor assembly job. The hex heads gripped my socket without slipping, and the 80mm length gave just enough bite for a metal bracket setup.

The partially threaded design made these grab perfectly for my equipment frame bolts, and the hex heads seated cleanly with a socket drive. The class 10.9 steel feels seriously robust for the price, plus the yellow zinc held up through a greasy shop session without a speck of rust.
