• High mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable performance under heavy loads.
• Secure and easy installation with a 14mm hex drive and knurled head, allowing for firm grip and efficient torque application.
• Consistent thread engagement with Class 5g6g metric coarse threads, reducing the risk of cross-threading and improving assembly speed.
• Compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring safety and environmental responsibility.

Professional Applications & Engineering Value

This M27x3mm metric shoulder screw is engineered to address critical challenges in precision machinery and industrial assemblies. Made from 316 stainless steel, it resists corrosion in demanding conditions like chemical processing or marine applications, while the black oxide finish enhances surface durability. The 30mm shoulder diameter with minimal tolerance provides a stable bearing surface for rotating parts, reducing misalignment and wear in equipment such as conveyor systems, robotics, and automotive fixtures. Its coarse thread and Class 5g6g fit ensure quick, reliable fastening in high-vibration environments, minimizing downtime and maintenance costs for B2B clients seeking robust, long-term solutions.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm, with threads conforming to Class 5g6g for metric coarse applications. It meets ISO 7379 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
