براغي تثبيت مقبس بنقطة كوب 3/4-16 × 3/4 بوصة | فولاذ سبائكي (50 / عبوة)

The cup point on these set screws bites into the shaft really well, so I don't worry about them slipping under heavy vibration. They're also consistently machined across all 50 pieces, which saves me time during assembly.

Installing these in a tight flange assembly was effortless—the hex socket gripped securely with no stripping. The cup point bites into the shaft just right for a solid hold. Exactly what I needed for a precise, vibration-resistant fit.

The alloy steel feels dense and strong, and the cup point grabbed the shaft perfectly on my first attempt. These are a solid upgrade over the standard ones I've been using.
