1/4-20 X 1-3/8" 기계용 나사 | 플랫 헤드 슬롯 드라이브 | 18/8 스테인리스 스틸 (200개/팩)

I needed slotted flat heads for a marine hatch rebuild, and these 1/4-20s threaded perfectly into the original holes with no binding. The 18/8 stainless should hold up well against the salt spray.

Using these in a outdoor fire pit table I built, the 18/8 stainless is holding up perfectly against the rain and humidity without a speck of rust. The flat heads sit flush and the slotted drive felt more precise than I expected for the price per pack.

These screws were exactly what I needed for an outdoor gate repair, and the 18/8 stainless steel handles the weather perfectly so far. The flat head sits flush with the wood, and the slotted drive is easy to work with even when my hands are tired.
