M18-2.5 X 140mm 육각 머리 캡 나사 | 316 스테인리스 스틸 | 부분 나사산 (10개/팩)

Had to replace some rusted bolts on outdoor equipment, and these 316 stainless screws handled the job perfectly. The partial threading made alignment much easier than fully threaded ones I've used before.

Installed these on a marine dock railing, and the 316 stainless is holding up perfectly against the salt spray. The partial threading made it easy to align the joint without fighting the threads the whole way.

The hex head gives a solid grip with a wrench even at full torque, and the partial threading made alignment much easier during the build. These 316 stainless screws handled the outdoor exposure so far without a hint of rust, which is exactly what I needed.
