M4-0.7 X 35mm 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 나사산 | 316 스테인리스 스틸 (400개/팩)

The hex socket drive grabbed my Allen key perfectly on the first try, no stripping at all. I’m using these 35mm 316 stainless steel screws for a long-term machinery setup, and the partial threading gives me excellent grip without bottoming out.

Used a handful of these for a jig I’m building outdoors, and the 316 stainless steel already feels more durable than the cheap zinc ones I’ve used before. The hex socket drive bit snugly, and the partial threading held firm without stripping.

I needed corrosion-resistant fasteners for a marine jig I’m building, and these 316 stainless steel screws threaded in perfectly without binding. The hex socket drive held up to repeated torque without stripping.
