• Reliable thread engagement due to Class 6g thread fit and coarse M4 x 0.7mm pitch, ensuring consistent performance and easier alignment in various materials.
• Broad industrial compatibility as a headless set screw conforming to DIN 915 / ISO 4028 standards, guaranteeing interchangeability and quality in global machinery and equipment.
• Environmental and regulatory safety with full RoHS 3 and REACH compliance, making it suitable for use in regulated industries without hazardous substance concerns.
• Optimized for right-hand thread applications with a 14mm length and extended tip, offering versatile and secure fastening in shafts, collars, and pulleys.

Professional Applications & Engineering Value

This M4 set screw is engineered to address critical challenges in industrial assembly, where vibration loosening and component slippage can lead to equipment failure. The extended tip (2.25mm length) creates a deeper indentation in the mating part, significantly enhancing grip and resistance to rotational forces in shaft-hub connections and precision machinery. Manufactured from alloy steel and hardened to Rockwell C45, it withstands repetitive stress and harsh environments, reducing maintenance needs. The hex drive and coarse metric thread (M4 x 0.7mm) ensure quick, secure installation with standard tools, streamlining production workflows. Ideal for automotive, manufacturing, and aerospace applications, this screw delivers consistent performance under high-torque conditions while meeting international DIN 915 / ISO 4028 specifications for reliability.

Specification Summary & Compliance

This set screw adheres to precise dimensional tolerances, including a Class 6g thread fit for consistent engagement and tip dimensions (diameter: 2.5mm, length: 2.25mm) with tight tolerances for accuracy. It conforms to DIN 915 and ISO 4028 standards, ensuring compatibility with metric fastener systems. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for safe use in industrial and export markets.
