HOLO-KROME 87146 M8-1.25 X 60mm 內六角螺絲 | 平頭六角驅動 | 合金鋼熱處理黑氧化 (100/包)

Needed some longer bolts for a jig I'm building, and these M8s are exactly the right length and the black oxide coating looks solid. They threaded in smoothly with no binding on my test piece.

The hex drive seats perfectly with a ball-end Allen key, and the black oxide finish has that slick, almost oily feel that resists rust well. Used a full bag on jigs and precision assemblies, every single one threaded clean without a single stripped or burred thread.

The black oxide finish on these M8-1.25 screws is holding up great in my jig setup, no rust or galling after a week of use. They're exactly 60mm long as listed and fit the hex drive perfectly.
