M3-0.5 x 5mm 소켓 캡 나사 | 육각 소켓 드라이브 | 전체 나사산 | 316 스테인리스 스틸 (1200 / 팩)

Finally got my hands on a full box of these 316 stainless M3 screws—the fully threaded design holds better in thin brackets than the partially threaded ones I used before.

The hex socket drive on these M3 screws is surprisingly precise, making them easy to tighten even in tight spots. I used a full pack for a precision assembly and every single one threaded smoothly without any burrs. The 316 stainless steel gives me confidence they’ll hold up in a slightly damp shop

Used these for a jig I was building and the 316 stainless finish is noticeably cleaner than the cheaper alternatives I’ve tried. They thread in smoothly without binding, which is exactly what you need for precision assemblies.
