- Enhanced durability and wear resistance from the Black Oxide finish, providing a protective layer against abrasion and galling.
- High-strength performance with a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi for reliable load-bearing applications.
- Precise and secure fit due to the Class 3A thread fit, ensuring tight tolerances and reduced risk of loosening under vibration.
- Easy installation and removal with a hex socket drive and knurled head, offering superior grip and torque transmission.
- Optimized for coarse threading applications with UNC 6-32 threads, allowing for quicker assembly and better performance in softer materials.
- Compliance with environmental and safety standards, including RoHS 3 and REACH, ensuring safe use in regulated industries.
Professional Applications & Engineering Value
This 316 Stainless Steel Shoulder Screw is engineered to address critical challenges in precision assembly and motion control systems. The Black Oxide finish not only enhances corrosion resistance but also reduces friction, making it ideal for rotating parts and industrial fasteners in machinery. The UNC coarse threading and Class 3A fit provide a secure, vibration-resistant connection, essential for applications like pivots, spacers, and guides in automotive, aerospace, and electronics. With a Rockwell B79 hardness and high tensile strength, it withstands repetitive stress and harsh conditions, reducing maintenance downtime and ensuring long-term reliability in demanding environments.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a precise Class 3A fit for tight dimensional accuracy. Key specifications include a thread size of 6-32, coarse thread spacing, and a shoulder diameter tolerance of -0.004" to -0.002". It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
