Professional Applications & Engineering Value
This 8-32 UNC thread socket head cap screw is engineered to solve critical fastening challenges in demanding industrial settings. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive assemblies, and outdoor equipment exposed to moisture and chemicals. The coarse UNC thread and Class 3A fit ensure quick assembly and a secure hold, reducing the risk of loosening in high-vibration environments. Its partially threaded shank and 3-inch length offer versatility for applications requiring a precise grip length and unthreaded section for alignment. The hex socket drive enables high-torque installation without stripping, which is crucial for maintenance and production lines where reliability and speed are paramount.
Specification Summary & Compliance
This screw features a 3" length with a minimum thread length of 1-1/8", UNC coarse thread with a Class 3A thread fit for precise tolerance, and a 9/64" hex drive. It is manufactured in compliance with ASME B18.3 and ASTM F837 specifications. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for hazardous substances.
