براغي ماكينة 1/4-20 × 4 بوصة | رأس تراس بمحرك فيليبس | ستانلس ستيل 18/8 (100 / عبوة)

I needed some longer machine screws for a deck repair project, and these 4-inch stainless steel truss heads threaded into the existing holes perfectly. The 18/8 material feels solid and should hold up well against the weather.

These screws feel solid and the truss head sits flush enough for my metal brackets. The non-magnetic property is a nice bonus since I'm using them near electronics, and the Phillips drive took some torque without stripping.

Wanted stainless screws that wouldn't rust on my boat trailer, and these truss heads sit flush enough to not catch on lines. The 4-inch length gave me plenty of bite into the wood stringers.
