براغي ضبط ذات رأس كروي مسنن 1/2-13 × 1-1/2 بوصة | فولاذ سبائكي (100/عبوة)

I work on heavy machinery and these set screws are exactly what I needed—the hex socket drive lets me torque them down securely even in cramped spots. The knurled cup point really digs in and holds tight, and at 100 per pack, it's a solid value for the shop.

The knurled cup point grabbed my shaft tightly even under heavy vibration, and the alloy steel feels durable enough for repeated adjustments. These set screws were exactly what I needed for a stubborn pulley repair.

The hex socket drive made torquing these into a tight spot on my press frame so much easier than using a standard hex key. The knurled cup point tip looks clean and professional against the steel surface.
