Stainless Steel DIN914 Set Screw


The DIN 914 set screw is a precision-engineered fastener adhering to the German DIN standard. Notable specifications include a hexagon socket drive for easy installation, a cone point design for high-pressure contact and secure holding, and a metric thread with specific pitch and diameter. Manufactured from materials like steel or stainless steel, the set screw may feature various surface finishes. Available in diverse sizes, specified by diameter and length, DIN 914 set screws are versatile components suitable for a range of applications, ensuring reliable and precise performance. For detailed specifications, it is recommended to refer to the official DIN 914 standard document or consult with suppliers adhering to DIN specifications.

Product Name:DIN914 Set Screw
The diameter of a DIN 914 set screw is specified by its nominal size, usually denoted with the letter "M" followed by a number. For example, M3 represents a 3mm nominal diameter set screw. The diameter is a crucial dimension, and it determines the size of the threaded portion of the screw. Different applications require set screws with specific diameters to ensure a proper fit and secure fastening.
LengthThe length of a DIN 914 set screw is specified as the distance from the bottom of the head to the tip of the screw. This dimension is crucial for determining how deeply the screw will penetrate into the material. The length is denoted numerically after the "x" in the size designation. For instance, in M4x12, the length is 12mm. Choosing the right length is essential to ensure that the set screw provides the necessary grip and holding power without protruding excessively.

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 DIN914 Hexagon Socket Set Screw:

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.
