#4-40 × 1/2" براغي ضبط بنقطة مسطحة مقبس | نحاس (50 / عبوة)

Perfect fit for securing a small gear onto a 1/8” shaft, and the brass finish blends nicely with the rest of the assembly. The flat point really helps it bite into the shaft without marring the surface.

The brass finish on these set screws looks really clean against the nickel-plated collar I'm using. They threaded smoothly into the hole and hold the pulley tight without any wobble.

Just the right size for my small pulley setup, and the brass feels solid when I thread them into the collar. The flat point seats nicely against the shaft without marking it up, and the hex drive worked cleanly with a standard allen key. Pack of fifty means I've got spares for the next project.
