- Rockwell B85 hardness enhances durability and wear resistance, maintaining thread integrity through repeated use.
Professional Applications & Engineering Value
This 8-32 UNC flanged rounded head screw is engineered to address common industrial challenges such as material fatigue and assembly time. The 18-8 stainless steel offers superior resistance to oxidation and chemicals, making it suitable for demanding applications in machinery, automotive assemblies, and outdoor equipment. Its coarse thread and fully threaded design ensure quick, secure fastening in softer metals or plastics, reducing the risk of cross-threading. The integrated flange acts as a built-in washer, providing stable clamping force and preventing surface damage. With a right-hand thread and hex drive, it supports efficient installation in tight spaces, enhancing productivity in high-volume manufacturing and maintenance operations.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The specifications include a length of 3/8", flange diameter of 0.656", and full threading for reliable performance in industrial fastening applications.
