Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and chemical exposure
- Enhanced durability and wear resistance from the black oxide finish, providing long-lasting performance and reduced maintenance
- Precise alignment and secure assembly ensured by the Class 3A thread fit and standard shoulder fit for minimal play
- High mechanical strength with 70,000 psi tensile and 35,000 psi shear strength, suitable for heavy-duty applications
- Easy installation and removal with the hex socket drive and knurled head for superior grip and torque application
- Reliable performance in regulated industries due to compliance with ASME B18.3, RoHS 3, and REACH standards
- Accurate positioning facilitated by the fine 10-32 UNF thread and consistent shoulder diameter tolerances
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw with black oxide finish is engineered to address critical challenges in precision assemblies, such as in machinery, automotive, and aerospace sectors. The Class 3A thread fit and fine 10-32 UNF thread ensure tight tolerances, reducing vibration-induced loosening and enhancing component alignment. The knurled head and hex drive design allow for efficient installation in confined spaces, while the robust shoulder diameter and length provide stable bearing surfaces for rotating parts. Ideal for applications requiring high tensile and shear strength, this screw minimizes downtime and maintenance costs in demanding environments, supported by its corrosion-resistant material and compliant finish.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit with precise dimensions, including a shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". It adheres to ASME B18.3 standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and reliability for industrial use.
