M6 x 25mm 컵 포인트 육각 소켓 세트 나사 | 316 스테인리스 스틸 (250개/팩)

I needed some stainless hardware that wouldn't seize up in a damp outdoor railing project, and the 316 grade on these screws gives me real peace of mind. The cup point tip seated perfectly flush without any splitting.

These screws held up great in a saltwater application I tried, no rust at all after weeks of exposure. The hex drive let me torque them down really tight in a cramped bracket.

These are perfect for securing a pulley on a motor shaft where space is tight—the hex socket lets me get good torque without any slipping. The 316 stainless feels solid and should hold up well in our slightly damp workshop.
