Professional Applications & Engineering Value
This stainless steel shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial applications. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive, and electronic assemblies exposed to moisture or chemicals. The 3/4" shoulder length with precise tolerances allows for accurate positioning of moving parts, reducing wear and misalignment. Combined with a 10-32 UNF fine thread and Class 2A fit, it ensures tight, vibration-resistant connections in high-stress environments. The hex socket drive and knurled head facilitate easy installation and removal, enhancing maintenance efficiency while maintaining high tensile and shear strength for reliable performance.
Specification Summary & Compliance
This shoulder screw features a 10-32 UNF thread with Class 2A fit for precise thread engagement and standard tolerances. The shoulder diameter and length adhere to specified tolerances (e.g., shoulder diameter: -0.004" to -0.002", shoulder length: -0.005" to 0.005"), ensuring consistent dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use without hazardous substances.
