Key Features & Benefits at a Glance
- Superior holding power with Rockwell C45 hardness for reliable, vibration-resistant fastening in demanding applications.
- Precise Class 5g6g thread fit ensures easy assembly and consistent performance, reducing the risk of cross-threading.
- Hex drive design provides high torque transmission and secure installation, even in confined spaces where a headless profile is required.
- Cup point tip bites firmly into the contact surface, creating a strong, non-slip connection that prevents component movement.
- Coarse thread spacing (0.7mm pitch) enables quicker installation and robust engagement, ideal for general industrial use.
- Manufactured from durable alloy steel for excellent strength and wear resistance, extending the service life of your assemblies.
- Compliance with DIN 916/ISO 4029 standards guarantees dimensional accuracy and interchangeability, ensuring part reliability.
Professional Applications & Engineering Value
This M4 set screw is engineered to solve critical challenges in industrial assembly, where vibration resistance and secure positioning are paramount. The alloy steel construction, hardened to Rockwell C45, provides the necessary durability to withstand dynamic loads without loosening. Its headless and hex drive design is ideal for applications with limited clearance, such as securing collars, gears, and pulleys on shafts. The cup tip concentrates force on a small area, digging into the shaft material to prevent axial slippage, making it a reliable choice for machinery, automotive components, and precision equipment where metric coarse threads are specified for robust, quick assembly.
Specification Summary & Compliance
This set screw conforms to DIN 916 / ISO 4029 specifications with a Class 5g6g thread fit for standard tolerance. The M4 x 0.7mm coarse thread and 12mm length ensure dimensional precision. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting environmental and safety standards for industrial use.
