M3-0.5 X 14mm 소켓 캡 나사 | 육각 소켓 드라이브 | 풀 나사산 | 316 스테인리스 스틸 (900개/팩)

Been hunting for decent M3s that won't corrode in a damp workshop, and these 316s with the hex socket drive are exactly what I needed for my jigs. The threads are clean, every one of the 900 seats perfectly without any binding, and the extra length on the 14mm gives plenty of grip.

The 316 stainless steel feels properly marine-grade—no rust spots after a week in a damp workshop. All 900 screws threaded cleanly into my jig without a single stripped head, which is more than I can say for cheaper packs.

Replaced some cheap hardware on my precision tooling setup and these 316 stainless M3s fit perfectly without galling. The hex drive seated cleanly and the threading was consistent across all 900 pieces.
