Professional Applications & Engineering Value

This 10-24 UNC Shoulder Screw is engineered to address critical alignment and stability challenges in precision assemblies. The 18-8 Stainless Steel material provides inherent corrosion resistance, making it suitable for applications in moist or chemically aggressive environments, such as industrial machinery, automotive fixtures, and electronic enclosures. The precise shoulder fit with tight diameter and length tolerances ensures minimal radial play, which is crucial for pivoting mechanisms, rotating shafts, and bearing retention. The coarse UNC thread and Class 2A fit facilitate quick assembly while maintaining secure fastening, reducing the risk of loosening under vibration. The passivated finish further enhances surface durability and prevents galling, extending the component's lifecycle in high-cycle applications.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder features a diameter of 1/4" with a tolerance of -0.001" to 0" and a length of 5/16" with a tolerance of 0" to 0.002", ensuring precise fitment. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe industrial use.
