براغي تثبيت برأس مقبس بنقطة كوب مقاس 3/4-10 × 2-3/4 بوصة | فولاذ سبائكي (10 / عبوة)

These cup point screws bit into my steel shaft without slipping, even under heavy load. The alloy steel feels sturdy, and the hex drive held up well to my impact driver.

The hex socket drive made these incredibly easy to install in a tight spot where a standard wrench wouldn't fit, and the cup point tip gripped perfectly without stripping. Exactly the length and threading I needed for a heavy-duty metal bracket.

Bought these for a stubborn shaft coupling at work, and the cup point really bites into the metal without slipping even at high torque. The 10-pack is a solid deal for the quality.
