DIN 916 Hexagon Socket Set Screws with Cup Point

Metric DIN 916 hexagon socket set screws with cup point have a hexagonal drive on one end and a cupped (concave) surface on the other. The threads are generally metric coarse, but there are also fine thread specifications. The cupped end features a circular arc shape, which creates a strong engagement force on the workpiece. It is suitable for anti-vibration, anti-loosening, and fixing the relative position of parts such as gears, couplings, and pulleys.
