S-91273A806 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Enhanced durability and wear resistance from the black oxide finish, reducing maintenance needs
• Precise alignment and secure component positioning thanks to the 12mm shoulder with tight length tolerance (±0.25mm)
• High mechanical strength with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing
• Accurate and consistent threading with Class 5g6g thread fit, ensuring smooth assembly and interchangeability
• Easy installation and removal via the hex socket drive (3mm) and knurled head for improved grip
• Compliance with environmental standards including RoHS 3 and REACH, supporting sustainable manufacturing practices

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical assembly challenges in industrial applications such as machinery, automotive systems, and precision instruments. The 18-8 stainless steel material offers excellent resistance to rust and oxidation, while the black oxide finish enhances surface durability and reduces friction during operation. The 12mm shoulder length with minimal tolerance ensures precise alignment of components, preventing misalignment and reducing wear on moving parts. With a coarse 1mm pitch thread and Class 5g6g thread fit, it provides secure fastening and easy installation in high-vibration environments. The hex socket drive and knurled head design facilitate quick tool engagement, streamlining maintenance and reducing downtime in production lines.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M6 thread size and 1mm coarse pitch. The thread fit conforms to Class 5g6g for precise dimensional accuracy, while the shoulder diameter tolerance is maintained between -0.04 to -0.01 mm. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material sustainability. The screw features a Rockwell B55 hardness and is designed for reliable performance in demanding engineering applications.
