M6-1×16mm 소켓 캡 나사 | 버튼 헤드 육각 소켓 드라이브 | 풀 스레드 | 클래스 10.9 합금강 아연 도금 (600개/팩)

I was impressed with the uniform zinc plating on these socket cap screws; every single one in the 600-count pack had clean, burr-free threads. The hex socket drive made them easy to install with a standard Allen key, and they held firm in my jig setup without stripping.

Got these for a batch of precision assembly jigs and the hex socket drive made tightening them in tight spots way easier than expected. The zinc plating looks clean and consistent across the whole pack, and all 600 pieces threaded smoothly without any binding.

Used a handful to repair a jig at work and the hex socket drive made them easy to install in a tight spot. The class 10.9 alloy steel feels rock solid, and the zinc plating looks clean and uniform. For the price per pack, these are exactly what I needed for precision assemblies.
