Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and heavy-duty equipment. The UNC coarse thread and Class 3A fit provide tight tolerances that minimize vibration and loosening, essential for dynamic loads. The Black Oxide finish enhances corrosion resistance, making it suitable for moist or chemically aggressive environments. With a knurled head and hex drive, it ensures secure tool engagement, reducing installation errors. Ideal for pivots, spacers, and rotating assemblies, this screw delivers reliable performance where high tensile and shear strength are paramount, supporting industries like aerospace, automotive, and industrial manufacturing.
Specification Summary & Compliance
The screw adheres to UNC thread standards with a Class 3A fit for precise thread engagement. Dimensions include a thread size of 8-32, shoulder diameter of 7/32" (tolerance: -0.004" to -0.002"), and shoulder length of 1 1/4" (tolerance: -0.005" to 0.005"). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial applications.
