Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw is engineered to address critical challenges in precision assemblies, such as maintaining exact part alignment and resisting wear in high-stress environments. The 10-24 UNC coarse thread and Class 3A thread fit ensure minimal backlash and reliable fastening, while the passivated finish enhances corrosion resistance, making it ideal for automotive, aerospace, and industrial machinery. The knurled head and hex drive facilitate easy handling and installation, reducing assembly time. With a 3/8" shoulder length and tight diameter tolerance, it provides stable pivoting and spacing, solving common issues like misalignment and component wear in rotating mechanisms.
Specification Summary & Compliance
This shoulder screw features precise dimensions, including a shoulder diameter of 1/4" (tolerance: -0.001" to 0.001") and shoulder length of 3/8" (tolerance: -0.005" to 0.005"), with a Class 3A thread fit and UNC coarse thread for high accuracy. It complies with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence in industrial applications.
