M5-0.8 x 16mm 소켓 캡 나사 | 육각 소켓 드라이브 | 전체 나사산 | 클래스 8.8 합금강 열처리 블랙 옥사이드 (600개/팩)

I needed a bulk pack of M5s for a jig setup and these came in perfect—the hex socket drive grabs well with my Allen keys. The 600 count means I won't run out mid-project, and the black oxide coating kept them rust-free during a humid week in the shop.

These black oxide screws held perfectly when I used them to build a new fixture for my drill press. The hex socket drive made them easy to torque down without stripping.

Finally got these M5-0.8 x 16mm socket cap screws for some tooling jigs, and the black oxide finish is holding up great against minor oil spills. The hex socket drive lets me torque them down precisely without stripping. Solid hardware for the price.
