براغي تثبيت بنقطة كوب مقاس 3/4-10 × 1-1/4 بوصة من هولو-كروم 32262 | فولاذ سبائكي بأكسيد حراري أسود (25 / عبوة)

Bought these to secure a sprocket on a keyless shaft, and the cup point bites in perfectly without slipping. The black oxide finish on these 3/4-10 set screws looks and feels robust for heavy use.

Needed a set screw for a stubborn pulley on a milling machine shaft, and these cup points really bite into the metal. The hex drive seats perfectly without stripping, even under torque from a long Allen key. Exactly what I needed for a secure hold.

The thermal black oxide finish on these screws is way more durable than I expected—didn't chip at all when I torqued them into a steel shaft. Cup point design seated flush with no fuss.
