Question: What is a flat head socket screw?

Answer:A flat head socket screw, also known as a Flat Point Grub Screw or Socket Set Screw, is a threaded fastener with no protruding head, intended for applications where a flush surface is required. It features a hexagon socket drive for operation with a hex key and a flat tip that provides a large surface area to prevent damage to a target housing.

Answer: The ISO equivalent for the DIN 913 standard is ISO 4026. The GB (Chinese National Standard) equivalent is GB/T 77-85. These standards all refer to Socket Set Screws with Flat Point.

Question: How many types of Set Screw Point are there?

Answer: While the provided materials focus on the Flat Point, set screws are commonly available with several other point types, including cup point, cone point, oval point, and dog point. The Flat Point is characterized by its large, flat surface area.

Question: What is the difference between a cup point and a flat or a cone point set screw?

Answer: The primary difference lies in the tip design and its application. A cup point has a concave tip that digs into the contact surface for maximum resistance to rotation. A flat point has a large, flat surface area that distributes pressure and prevents damage to the target housing. A cone point has a pointed tip that creates a deep indentation for secure positioning.
