براغي رأس أسطوانية M10-1.5 × 90 مم | محرك سداسي داخلي | سن جزئي | فولاذ مقاوم للصدأ 316 (50/عبوة)

I needed a batch of 316 stainless screws for a marine railing repair, and these m10-1.5 x 90mm cap screws fit the bill perfectly—the partially threaded design made alignment into tapped holes much easier than fully threaded ones I've used before. Survived a week of salt spray without a speck of rust

Finally, a hex cap screw that doesn't start to pit after a few months in a damp environment. The 316 stainless held up perfectly on some outdoor sign brackets I just built.

Installed a set of these in a jig fixture yesterday, and the partially threaded shank made alignment way easier than fully threaded bolts. The hex socket drive grabbed tight without stripping, which I appreciate.
