Key Features & Benefits at a Glance
- Superior corrosion resistance thanks to 18-8 stainless steel construction and passivated finish, ideal for harsh environments.
- Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for reliable, long-term performance under load.
- Precise, secure fastening ensured by Class 3A thread fit and UNC coarse threading, reducing the risk of cross-threading and loosening.
- Efficient installation and removal with the hex drive design and 5/64" drive size, providing excellent torque transmission.
- Versatile rounded (button) head profile offers a low-profile, finished appearance while minimizing snagging in assembled products.
- Full threading along the 1-1/8" length allows for maximum grip and adjustability in a wide range of material thicknesses.
- Compliance with major industry standards including ASME B18.3, ensuring consistent quality and interchangeability.
Professional Applications & Engineering Value
This 6-32 UNC screw is engineered to address critical needs in precision assemblies where corrosion resistance and high tensile strength are non-negotiable. The combination of 18-8 Stainless Steel and a passivated finish provides a robust defense against oxidation and chemical exposure, making it suitable for electronics, machinery, and outdoor equipment. The rounded head with hex drive ensures a flush fit and secure torque application, preventing stripping and enabling efficient maintenance. Its Class 3A thread fit and coarse thread spacing facilitate quick assembly and reliable performance in vibration-prone applications, reducing downtime and maintenance costs for industrial users.
Specification Summary & Compliance
This screw adheres to strict dimensional and performance criteria, including a Class 3A thread fit for precision, UNC thread form, and manufacturing per ASME B18.3 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial and consumer applications.
