5/16-18 X 1/2 英吋機械螺絲 | 傘頭十字驅動 | 18/8 不鏽鋼 (200 顆/包)

Was a bit worried the truss head would look odd in my application, but the low profile actually sits perfectly flush against the bracket. These 18/8 screws held up great after a week of outdoor moisture, no rust forming at all.

I needed stainless screws that wouldn't rust on an outdoor gate project, and these 18/8 ones held up perfectly through a few rainstorms. The truss head sits flush without stripping, and a full package of 200 was more than enough for the job.

These little stainless screws were perfect for reassembling a vintage outdoor sign; the 18-8 grade handles the weather far better than the old zinc ones did. No rust after two weeks of rain, and the truss head sits nice and flush.
