براغي آلية 5/16-18 × 3/4 بوصة | رأس مسطح فيليبس | فولاذ مقاوم للصدأ 316 (200 / عبوة)

Installed these on a dock repair project and the 316 stainless held up perfectly against the saltwater spray during installation. The flat head sits flush and the Phillips drive bites nicely without camming out.

The non-magnetic property is a huge plus for my electronics bench, and the flat heads sit perfectly flush in counterbored holes. Three hundred and sixteen stainless means I'm not worried about these rusting out in my shop's humid air.

Took these to the boat for a small repair and the 316 grade held up perfectly after a week of salt spray, zero rust spots. The flat head sits flush in the countersink like it should, and the Phillips drive didn't strip once.
