  • Fully-threaded, headless screw with a hex drive at one end and a protruding tip with a flat surface at the opposing end. Posseses an oval-shaped point on the end opposing the flush hex drive.
  • Torsional Strength Socket set screws of sufficient length should be tested to determine if that can withstand the application of the test torque outlined in the above table without evidence of the socket reaming or the screw bursting.
  • Half-Dog Point Oval Point
  •  For permanent setting - often used instead of a dowel pin. The point should closely fit the diameter of the drilled hole, or alternatively, against the flat. The preferred style for frequent re-set on soft or hard shafts with minimum deforming. Often used for permanent setting on shafts that are spotted, splined or grooved, and for applications where the point meets the shaft on an angle. Sometimes sub
  •   Cup Point
  • Description Fully threaded, headless screw with a hexagonal drive at one end and a cup-shaped indentation at the other.
  • Flat Point Cone Point
  • Finish Black Thermal Finish
  • Applications/ Advantages Most used style Designed for fast, permanent and semi-permanent location of parts on shafts with a hardness differential of 10-15 Rockwell C points and where cutting in of the cup edge on the shaft is acceptable.
  • Posseses a flat surface at the end opposing the hexagoal drive.   Has a shart conical-shaped point at the opposite end from the hexagonal drive.
  • Heat Treatment Set screws should be heat treated via oil quenching from above the transformation temperature and then tempered at a temperature that is condusive to meeting the hardness requirements.
  • Hardness Rockwell C45 - 53

the cup point is the most comonly used set screw. It has a cup-shaped indentation on one end. The cup point is used for quick, permanent and semi-permanent part assemblys and where the cutting in of the cup point edge is acceptable.
