M22-2.5 X 90mm 육각 헤드 캡 나사 | 클래스 10.9 강재 옐로우 징크 | 부분 스레드 (10개/팩)

The threads are clean and the yellow zinc coating gives them a solid, uniform finish. I used these to bolt down a heavy jig on the shop floor and the 90mm length with partial threading made alignment easy. Exactly what you need for a job where you don't want to second-guess the hardware.

The shoulder on these bolts sits flush against the flange, and the partial threads grabbed cleanly in the tapped holes without any binding. Yellow zinc coating looks even and should hold up fine on the shop floor.

The yellow zinc finish is holding up nicely on our assembly line, and the partially threaded design made seating these into the frame a breeze. Wrench fit on the hex head is snug with no rounding, even after torquing a few to spec. These are a solid pick for heavy bolting jobs.
