Professional Applications & Engineering Value
This Nickel Alloy shoulder screw is engineered to address critical challenges in precision machinery, such as alignment stability and component wear. Its 1/4" shoulder diameter and 1" shoulder length provide a robust pivot or spacer in assemblies, reducing misalignment and extending equipment life. The Class 3A thread fit and coarse UNC threads ensure secure fastening with high repeatability, essential for automated systems and heavy-duty applications. With a Rockwell B60 hardness and high tensile strength, it resists deformation under stress, making it suitable for aerospace, automotive, and industrial equipment where reliability is paramount. The knurled socket head enhances installation ease, minimizing downtime in production environments.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread size with Class 3A fit for precise tolerance, and a shoulder diameter tolerance of -0.004" to -0.002" for consistent performance. It meets ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) with exemption 6(c), as well as REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence in industrial use.
