براغي تثبيت بنقطة كوب M8 × 45 مم | فولاذ سبائكي (100 / عبوة)

After struggling to get a stubborn pulley to grip its shaft, these M8 cup point screws finally did the trick—the hex socket let me really torque them down in a tight spot. The alloy steel feels solid, and the 100-pack means I've got plenty for future projects.

These set screws were perfect for securing a pulley to a shaft; the cup point bit in nicely and held fast under load. The alloy steel feels really solid, and the M8 size threaded smoothly into pre-tapped holes.

The hex socket drive made tightening these in my lathe's tailstock much easier than using a hex key. The alloy steel feels sturdy and the cup point bites into the shaft securely without stripping.
