Specification:
The DIN 913 set screw is a precision-engineered fastener adhering to the German DIN standard. Notable for its flat point, this set screw provides a flush installation and is commonly crafted from materials like steel or stainless steel. Featuring a hexagon socket drive for ease of use, it conforms to metric threads with various surface finish options. Available in diverse sizes, the DIN 913 set screw is a versatile solution widely applied in machinery, automotive, and electronics, offering secure fastening with a focus on precision and reliability. Here are some common specifications for set screws:
| Product Name: | DIN913 Set Screw |
| Diameter | M1.4-M24 The diameter of a Din913 set screw refers to the measurement across the screw, typically at the widest point. This is often specified using the metric system, such as M3, M4, M6, etc. These values represent the nominal diameter of the screw and help in choosing the appropriate size for a particular application. |
| Length | The length of a Din913 set screw is the measurement from one end (usually the bottom of the head or the point, depending on the design) to the other end. It represents how far the screw extends into the material it's securing. |
| Class | Steel: 45H Stainless Steel；A2-70，A4，C3，A2-50 |
| Type | Hexagon socket set screw with a flat point. |
| Material | High-strength steel (e.g., SCM435) Alloy steel (e.g., ML40CR) Medium to low-carbon steel Copper Aluminum Stainless steel |
| Manufacturing Process | wire drawing, cold heading, thread rolling, heat treatment, surface treatment |
| Surface treatment | Black Oxide Coating/Zinc Plating (Electroplating)/Hot-Dip Galvanizing/Mechanical Galvanizing/Dacromet Coating/Painting or Powder Coating |
When specifying set screws, it’s important to consider the requirements of your application to ensure that the chosen set screw is compatible with the materials, forces, and conditions it will encounter.
Dimension Chart of DIN913:
1. Thread Diameter (d): The thread diameter of a DIN 913 set screw refers to the main diameter of its threads, typically measured in millimeters.
2. Thread Pitch (p): Thread pitch indicates the distance between threads on the screw and is measured in millimeters. It is a crucial dimension for DIN 913 set screws.
3. Hex Key Size (Across Flats) (s): The set screw features an internal hexagon socket for tightening with a hex key or wrench. Hex key size (across flats) is the distance between two parallel hexagonal sides of this socket.
4. Hex Key Depth (t): Hex key depth refers to the depth of the internal hexagon socket, representing the maximum depth a hex key can be inserted into the set screw.
5. Set Screw Length: This is the measurement from the bottom of the set screw (or from the end of the threads, in the case of headless set screws) to the end of the threads. It determines how deeply the screw can be threaded into a tapped hole or onto a shaft.
