براغي تثبيت سداسية بنقطة كوب 7/16-14 × 3/8" | فولاذ سبائكي (50 / عبوة)

The hex socket drive made installation straightforward with just an allen key, no stripped heads. These 50 screws are holding my collar firmly in place on the shaft, and the alloy steel feels sturdy enough for the job.

Used these to secure a pulley to a shaft and the alloy steel held up perfectly under load—no stripping or loosening at all. The cup point design made alignment easy during installation. Exactly what I needed for a reliable mechanical joint.

These cup point screws fit perfectly into the recessed socket on the gear I was mounting, and the alloy steel feels substantial. Was able to torque them down without any stripping, which is a relief. A solid, no-nonsense fastener for securing components to a shaft.
