Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to solve critical alignment and pivot point challenges in precision assemblies. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for machinery, food processing, and medical equipment exposed to moisture or chemicals. The 3-1/4" shoulder length acts as a precise datum for locating gears, bearings, or linkages, reducing assembly time and improving operational accuracy. The Class 3A thread fit and coarse UNC thread ensure robust performance in high-vibration environments, preventing loosening. With a socket head and knurled texture, it allows for efficient installation in confined spaces, enhancing productivity in automated and manual assembly lines.
Specification Summary & Compliance
This shoulder screw adheres to tight dimensional tolerances, including a Class 3A thread fit for superior thread engagement and a shoulder diameter tolerance of -0.004" to -0.002". It is manufactured in accordance with ASME B18.3 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free of hazardous substances and safe for use in regulated industries.
