M8-1.25 X 15mm 소켓 캡 나사 | 버튼 헤드 육각 소켓 드라이브 | 풀 나사산 | 클래스 12.9 합금강 아연 도금 (200개/팩)

The hex socket drive bit into these cleanly without any stripping, and the zinc plating looks uniform across all 200 pieces in the package. Just finished building a new tooling fixture and they torqued down smoothly to spec. Exactly what I needed for precision work, and the 12.9 grade gives me confi

Replaced about sixty of them in a jig today and every single one seated cleanly with no stripped threads. The hex drive holds the driver bit firmly, and the 12.9 alloy steel feels plenty rigid for tooling duty.

The zinc plating on these M8 screws feels robust and should resist rust well. I used them for a small jig, and the button heads sit flush perfectly. Exactly what my project needed.
