M30-3.5 x 180mm 육각 머리 볼트 | 316 스테인리스 스틸 | 부분 나사산 (5 / 팩)

Had to swap out some old bolts on a press, and these M30s fit perfectly in the hex socket without any thread binding. The 316 stainless feels solid and the partial thread made alignment much easier than fully threaded ones would have.

Used these to bolt down a heavy conveyor frame and the partial threading made alignment a lot easier than fully threaded would have been. The hex heads grabbed cleanly with a socket, no stripping even at full torque. Solid build quality for the price.

The machining on these 316 stainless cap screws is clean and precise, which made assembly straightforward. The partial threading was exactly what I needed for a tight fit in my equipment without extra play.
