M12-1.75 X 16mm 소켓 캡 나사 | 버튼 헤드 육각 소켓 드라이브 | 풀 스레드 | 클래스 10.9 합금강 아연 도금 (100개/팩)

These M12 button heads fit perfectly in the tight spots on my milling machine where a regular hex head wouldn't go. The zinc plating looks consistent and clean, and the 10.9 grade gives me confidence they’ll hold torque without stripping.

Needed some high-strength bolts for a heavy-duty press fixture, and these M12 button heads seated perfectly with my hex key. The zinc plating looks consistent across all 100 pieces, so they should hold up well in my shop environment.

Picked up a pack for some jig builds and was impressed how cleanly the zinc plating looks even under shop lights. The 10.9 alloy steel seems tough enough for my precision assembly work, and the hex drive bites clean without wobbling.
