About this category

Headless socket set screws, threaded the full length, that screw into a tapped hole and press against a shaft or part to hold it - typical on pulleys, couplings and knobs. The cup point is a hollowed end with a sharp rim that bites into the shaft, giving the strongest grip and the most general-purpose point. 3-12 mm thread.

Standards DIN 916 · ISO 4029

How to choose

• A cup point marks the shaft - mill a flat first if the part is repositioned often.
• The point decides the job: flat point to avoid marking, cone point to locate. Thread size alone is not enough.
• Set screws sit inside the hole; length is overall, so an over-long screw will protrude or bottom out.
