Carter A. ★★★★★

I needed a reliable way to stop a small pulley from sliding on a shaft, and these set screws grabbed it perfectly with the hex socket drive. The 100-count package left me with plenty of spares for future projects. Exactly the right grip without any strip-out so far.

Stella ★★★★★

Finally, a set screw that doesn't strip the hex socket under normal torque. The 100-pack gives me plenty for multiple projects, and these hold tight once seated.

George V. ★★★★★

Installed a dozen of these last weekend to secure a motor shaft coupler; the hex socket drive made it much easier to get a tight fit without stripping the head. They feel solid and haven't budged under vibration.
