Professional Applications & Engineering Value
This 10-24 UNC flat head screw is engineered to address critical needs in security-sensitive and demanding industrial settings. Made from 18-8 stainless steel with a passivated finish, it resists corrosion in moist or chemical-exposed environments, reducing maintenance costs. The tamper-resistant Torx Plus drive (IPR25) prevents unauthorized access, making it ideal for public infrastructure, machinery enclosures, and electronic assemblies where vandalism is a concern. Its coarse thread and Class 3A fit ensure quick, reliable installation with minimal thread stripping, while the fully threaded design and standard 82° countersink provide a secure, flush fit that maintains structural integrity under vibration and stress.
Specification Summary & Compliance
This screw features a 10-24 UNC coarse thread with Class 3A thread fit for precise dimensional accuracy, ensuring compatibility with standard nuts and tapped holes. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for international supply chains.
