DIN 914:1980 Hex Socket Cone Point Set Screw

DIN 914:1980 Hex Socket Cone Point Set Screw uses a sharp cone point and a hex socket drive to create strong localized positioning during tightening. It is suitable for connections that must resist rotation, sliding, or positional shift.

The cone point can engage with a prepared locating hole or a hard mating surface, improving positive locking. The hex socket supports higher torque application and is convenient for production lines and limited-clearance assembly areas, offering more controlled tightening than slotted set screws.

This product is commonly used for gears, pulleys, couplings, collars, adjustment rings, and machine tool accessories. It can be supplied with different hardness levels, materials, and finishes for mechanical environments involving vibration, wear, or corrosion concerns.
