• Secure and easy installation with a 12mm hex drive and knurled head, providing excellent grip and preventing tool slippage during torque application.
• Optimized for durability and aesthetics through a black oxide finish that adds mild corrosion protection and reduces light reflection.
• Guaranteed interchangeability with ISO 7379 standard compliance and Class 5g6g thread fit, ensuring consistent performance in metric assemblies.
• Environmentally responsible manufacturing meeting RoHS 3 and REACH regulations, supporting your compliance in global markets.

Professional Applications & Engineering Value

This M20x2.5 shoulder screw is engineered to address critical alignment and load-bearing challenges in precision industrial applications. The 316 stainless steel material provides excellent resistance to corrosive elements, making it suitable for machinery in marine, chemical, and food processing industries. The 100mm shoulder length with minimal tolerance acts as a precise axle or pivot, minimizing backlash and wear in assemblies like conveyor systems, robotic arms, and printing equipment. The coarse thread pitch and black oxide finish enhance installation speed and provide an additional layer of protection, ensuring long-term reliability and reducing maintenance costs. Its hex drive and knurled head design facilitate secure handling, even in high-vibration environments, delivering consistent performance for heavy-duty shoulder screw requirements.
