براغي آلية 5/16-18 × 4 بوصات | رأس مسطح فيليبس | فولاذ مقاوم للصدأ 18/8 (100/عبوة)

Picked up a pack of these for a deck repair project, and the flat head sits flush perfectly. The 18/8 stainless seems solid and the threads were clean right out of the box.

These threads are clean and straight, no burs or wobble when I seat them. The 304 stainless makes them a no-brainer for the washdown area I'm building, and the 4" length gives plenty of grip.

Had to order these for a project that needed extra length, and the 4-inch size was perfect for going through thick brackets. The threads are clean and the Phillips head drives in without stripping. Solid 304 stainless, no rust worries even outside.
