Professional Applications & Engineering Value
This 8-32 UNC left-hand thread shoulder screw is engineered to address common industrial challenges, such as vibration loosening and corrosion in demanding settings. The 18-8 stainless steel material offers excellent resistance to rust and chemicals, while the Class 3A thread fit ensures tight tolerances for high-stress applications like machinery, automotive systems, and precision instruments. The 3/16" shoulder diameter provides stable alignment for rotating components, reducing wear and maintenance needs. With its left-hand thread direction, it is ideal for assemblies where standard right-hand threads may unscrew under operational forces, enhancing safety and reliability in industrial screw applications.
Specification Summary & Compliance
This shoulder screw features precise dimensions, including a shoulder diameter of 3/16" with a tolerance of -0.004" to -0.002", and a shoulder length of 3/16" with a tolerance of -0.005" to 0.005". It adheres to UNC coarse threading standards with a Class 3A thread fit for superior accuracy. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for various industrial and engineering uses.
