براغي آلية 1/4-20 × 4" | رأس عريض فيليبس | فولاذ مقاوم للصدأ 316 (100 / عبوة)

The 316 stainless is noticeably non-magnetic, which mattered to me for the sensor mounts I was securing. All one hundred arrived clean and the truss heads give a solid grip without stripping. They've been through a couple of salt sprays already with zero spotting.

Put these on my boat's deck hardware last weekend; the 316 stainless held up perfectly against the salt spray. Truss head sits nice and flush, and the Phillips drive didn't cam out once.

For the price, getting a full hundred pack of these 316 stainless screws in this length is a steal. The truss head sits perfectly flush on my aluminum railing brackets without any interference, and I can already tell they won't pit or rust.
