1-14 x 3인치 소켯 캽 스크류 | 플래트 헤드 헥스 소켯 드라이브 | 풀 나사 | 알로이 스틸 서멀 블래크 옥사이드 (2개/팩키지)

Perfectly sized threads for my jig build, and the black oxide finish gave them a nice matte look that resists fingerprints. The flat head sat flush without any wobble, and the hex socket held up to a torque wrench without stripping. These will definitely be my go-to for precision work.

The hex socket drive on these screws is machined cleanly, so my Allen wrench gripped perfectly without any stripping during installation. They’re very solid for holding jig parts together, and the black oxide finish resists scuffs well.

The thermal black oxide finish is exactly what you want for tooling—no glare, no rust worries, and the hex socket grips the wrench with zero slip. Threads cut cleanly into the steel on my jig, and at this price for two, I’m already ordering more.
