Professional Applications & Engineering Value
This 8-32 UNC Class 3A zinc-plated alloy steel rounded head screw is engineered to address critical fastening challenges in demanding sectors such as machinery assembly, automotive manufacturing, and electronic enclosures. The zinc plating provides a durable barrier against oxidation and chemical exposure, extending service life in corrosive settings. Its fully threaded coarse UNC design and Class 3A fit deliver superior resistance to loosening under dynamic loads, while the flanged button head offers a low-profile, wide-bearing surface that minimizes the risk of pull-through in softer materials. With a 120,000 psi tensile strength and 3/32" hex drive, it ensures reliable performance in high-vibration applications, reducing maintenance needs and enhancing operational safety.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 3A thread fit for precise dimensional accuracy and interchangeability. It is manufactured from alloy steel with a zinc-plated finish, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring it is free from hazardous substances and suitable for global industrial use.
