DIN 913:1980 Hex Socket Flat Point Set Screw

DIN 913:1980 Hex Socket Flat Point Set Screw combines a hex socket drive with a flat point, providing stable clamping for collars, adjustment blocks, fixtures, and mechanical stop structures while reducing sharp damage to the contact surface.

The hex socket offers better torque transmission than a slotted drive and supports more efficient assembly. The flat point provides smooth contact and allows repeated adjustment, making it suitable for connections that must balance holding force with serviceability.

This set screw is commonly used in automation equipment, machine tool accessories, instrument mechanisms, transmission components, and industrial fixtures. It can be supplied in different strength classes, thread sizes, lengths, and finishes for standard or corrosion-sensitive environments.
