- Precise, secure fastening thanks to Class 2A thread fit and fine UNF threading, minimizing loosening under vibration.
- Efficient installation with No. 2 Phillips drive, allowing for quick, tool-compatible assembly.
- Full-thread engagement across the 1 3/4" length, providing consistent clamping force and stability.
- Regulatory peace of mind through compliance with ASME B18.6.3, RoHS 3, and REACH, meeting industry and environmental standards.
Professional Applications & Engineering Value
This 10-32 UNF screw with a rounded truss head is engineered to address critical challenges in industrial assembly, such as vibration-induced loosening and corrosion in exposed settings. The passivated 18-8 stainless steel material offers excellent resistance to oxidation and chemicals, making it ideal for electronics enclosures, automotive components, and outdoor machinery. The fine thread spacing and Class 2A thread fit ensure tight, reliable connections that withstand dynamic loads, while the wide head design distributes clamping force evenly, reducing the risk of surface cracking on softer materials. Fully threaded for maximum grip, these screws deliver consistent performance in demanding applications where precision and durability are non-negotiable.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit tolerances and UNF (Unified National Fine) thread standards, ensuring dimensional accuracy and interchangeability. Manufactured in accordance with ASME B18.6.3 specifications, it guarantees consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility for global supply chains.
