M20-2.5 x 60mm 육각 머리 볼트 | 클래스 10.9 강 옐로우 아연 도금 | 풀 스레드 (20개/팩)

Threads were perfectly clean and the hex heads fit my socket without any slop—exactly what I needed for a heavy jig assembly. The 60mm length was just right for bolting through two thick brackets with a nut to spare. These Class 10.9 bolts definitely feel tougher than the standard hardware store stu

Yellow zinc coating looks properly applied across every one of the 20, and the 10.9 grade steel threads cut cleanly into my equipment bracket without any binding. These are the kind of bolts you install and forget about.

The hex head fits my socket perfectly, and the class 10.9 steel feels solid and strong for securing heavy equipment. These M20 bolts threaded smoothly into the mounting bracket without any binding.
