Key Features & Benefits at a Glance
- Enhanced corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
- Precise alignment and secure positioning due to the 45mm shoulder with tight length tolerance (0 to 0.25 mm).
- High mechanical strength and durability from Rockwell B83 hardness and 70,000 psi tensile strength, ensuring reliable performance under load.
- Secure and efficient installation using a standard 5 mm hex socket drive, preventing cam-out and enabling high torque application.
- Accurate and reliable thread engagement with Class 5g6g thread fit and M8x1.25 coarse pitch for quick assembly.
- Knurled head texture for improved grip during manual handling and initial placement.
- Full compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring product safety and regulatory acceptance.
Professional Applications & Engineering Value
This M8 shoulder screw is engineered to solve critical alignment and rotational control challenges in industrial fasteners applications. Manufactured from 18-8 Stainless Steel, it provides excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive assemblies, and electronic enclosures exposed to demanding conditions. The 45mm shoulder length with precise tolerances ensures accurate component spacing and acts as a pivot or axle, reducing wear on moving parts. The hex socket drive and coarse thread pitch facilitate quick, secure installation, minimizing assembly time while maintaining high tensile strength. Ideal for use in precision instruments, conveyor systems, and robotic arms, this screw enhances overall assembly integrity and longevity.
Specification Summary & Compliance
The screw features a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing precise engineering fits. It is manufactured in accordance with ISO 7379 and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards.
