Professional Applications & Engineering Value
This 6-32 UNC coarse thread flanged button head screw is engineered to address common industrial challenges such as vibration loosening and corrosion. The black-oxide alloy steel construction offers excellent durability and resistance to rust, making it suitable for machinery, automotive, and electronics assemblies where exposure to harsh conditions is a concern. The wide rounded head profile and integrated flange provide a larger bearing surface, distributing clamp load effectively and preventing surface damage. With a right-hand thread direction and fully threaded design, it ensures quick, secure fastening in materials requiring coarse threading, reducing installation time and enhancing structural integrity in high-performance applications.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 3A thread fit for precise tolerance, ensuring consistent engagement. Dimensions include a 1/2" length, 6-32 thread size, and 0.297" flange diameter. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from hazardous substances. Manufactured from alloy steel with a hardness of Rockwell C32, it is designed for robust performance in industrial settings.
