براغي ماكينة 1/4-20 × 3 بوصة | رأس جمالون بمحرك فيليبس | فولاد مقاوم للصدأ 316 (100/عبوة)

Installed these on a dock gate near the water, and the 316 stainless steel shows zero signs of rust even after a month of salt spray. The truss head sits flush and gives a clean finish, plus the non-magnetic property is a nice bonus for metalworking projects nearby.

These are going to outlast the rest of my hardware stash, the 316 stainless is noticeably tougher than the standard stuff I've used before. The truss heads sit nice and flat, and the Phillips drive grabbed cleanly without stripping during install.

Had to replace some fasteners on my boat trailer and these 316 stainless screws went in clean with a standard Phillips bit. They're truly non-magnetic, which I tested with a magnet, and the truss head gives a nice low profile without stripping. Salt air won't be an issue with these.
