براغي مقبس بيضاوية الرأس 5/16-18 × 2-1/2 بوصة | فولاذ سبائكي (100 / عبوة)

The hex socket drive made seating these in a cramped gear assembly without slipping a real relief. Alloy steel feels properly hard, and the oval points aligned cleanly on the shaft. Exactly the torque-holding set screws I needed for the repair.

These oval point screws gripped perfectly when I needed to lock a shaft in place, and the 2-1/2" length was just right for my setup. The alloy steel feels solid and the hex drive didn't strip.

The hex socket drive made adjusting these screws in a cramped spot on my jig much easier than I expected. The oval point seated nicely without walking. A solid value for the price, though the packaging could be a bit sturdier.
