براغي رأس سداسي 5/16" X 4-1/2" | ستانلس ستيل 316 (300 / عبوة)

Used these for a deck railing project in a coastal area, the 316 stainless steel is already proving its worth against the salt air. Each screw bites into the wood cleanly with a pre-drilled hole, and the hex head grips the socket securely without stripping.

These were used to tie our pergola beams to the posts and they sunk in straight without any stripping. The 316 stainless finish gives me real peace of mind for coastal weather, and the box of 300 is enough for a whole project plus spares.

Went through a whole box building a dock in saltwater, and not a single one showed any rust after six months. The 316 stainless really holds up better than the standard ones I used before.
