HOLO-KROME 33092 براغي تثبيت بنقطة كوب مقاس 5/16-24 × 5/16" | فولاذ سبائكي بأكسيد حراري أسود (100 / عبوة)

These cup point screws fit perfectly in the shaft holes I was working on, and the hex drive made installation much smoother than standard set screws. The 5/16-24 thread grabbed cleanly without any stripping.

The black oxide finish on these set screws gives them a nice grip without feeling slick, and they held tight when I secured a small gear on a motor shaft. Worked exactly as needed for the price.

The hex socket drive seated perfectly into my jig, and the black oxide finish on these cup point screws looks much cleaner than the bright ones I used before. I've already bought two more packs for future builds.
