What are the Types of Set Screws Commonly Used in Door Handles?

There are several different types of set screws commonly used in door handles. The specific type of set screw used may vary depending on the design of the door handle and the manufacturer’s preferences. Here are a few commonly used types:

  • Cup Point Set Screw: This type of set screw has a concave or cup-shaped indentation on the end. The cup point creates a firm grip when tightened against a flat surface, providing good resistance to loosening. It is commonly used in door handles where the set screw is inserted into a drilled hole in the handle and tightened against a shaft or spindle.
  • Flat Point Set Screw: The flat point set screw has a flat end surface without any indentation. It provides a larger surface area of contact when tightened against a shaft or spindle, distributing the pressure evenly. Flat point set screws are suitable for door handles that require a flush surface against the shaft or spindle.
  • Oval Point Set Screw: Oval point set screws have an oval-shaped indentation on the end. The oval point provides a concentrated contact area, creating a secure grip when tightened against a shaft or spindle. It is often used in door handles where the set screw needs to be aligned with a groove or indentation on the shaft for added stability.
  • Cone Point Set Screw: This type of set screw has a pointed cone-shaped end. The cone point provides excellent grip and penetration into the shaft or spindle, ensuring a strong connection. Cone point set screws are commonly used in door handles where the set screw needs to penetrate and grip a slightly softer material, such as certain types of metal or plastic.
  • Knurled Cup Point Set Screw: Knurled cup point set screws feature a cup-shaped indentation on the end with a textured knurled surface. The knurled pattern provides enhanced grip and resistance to loosening, even in applications with vibrations or movement. This type of set screw is often used in door handles that require a more secure fastening in challenging conditions.

It’s important to note that the specific type of set screw used in a door handle may vary depending on the manufacturer’s specifications, the design of the handle, and the material of the shaft or spindle being fastened. It is always recommended to consult the set screw manufacturer’s guidelines or specifications for the appropriate set screw type and size for a particular door handle.
