M20-2.5 X 380mm 육각 머리 캡 나사 | 클래스 10.9 강철 무도금 | 부분 나사산 (2개/팩)

The partially threaded section grabbed perfectly on my lathe’s tool post, and the hex head took a socket without rounding. These M20s feel rock-solid for the price, and two in the pack is just right for the job I had.

Finally got the right bolts for my press jig. The 380mm length is exactly what I needed for the through-hole assembly, and these have held up to serious torque without any play.

The partially threaded design is exactly what I needed for bolting down heavy equipment, and the hex head grips cleanly with a standard socket. These 380mm screws feel rock solid, no flex in the steel at all. Shipped fast and the threads were perfectly machined, no burrs or damage.
