S-90046A119 10-32 x 1" NAS1801-3-16 High-Strength Steel Hex Head Screws with Phillips Drive

Key Features & Benefits at a Glance

• Exceptional tensile strength of 160,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
• Class 3A thread fit provides superior precision and tight tolerances for secure, vibration-resistant assemblies in critical applications.
• Cadmium plating offers excellent corrosion resistance, extending the screw's service life in harsh industrial environments.
• Partially threaded design allows for precise clamping force control and improved joint stability where full threading isn't required.
• Dual external hex/Phillips drive enables versatile installation options with common tools, speeding up assembly processes.
• Fine thread spacing delivers enhanced holding power and better resistance to loosening under dynamic loads.
• Compliance with NAS1801-3-16, RoHS 3, and REACH ensures adherence to aerospace and environmental standards, guaranteeing safety and regulatory acceptance.

Professional Applications & Engineering Value

This 10-32 UNF steel hex head screw is engineered to address critical challenges in aerospace, automotive, and heavy machinery sectors where vibration resistance and structural integrity are paramount. The cadmium-plated finish combats corrosion in exposed or high-humidity environments, while the Class 3A thread fit minimizes backlash and ensures consistent clamping force. Its partially threaded configuration is ideal for applications requiring precise unthreaded shank sections, such as in bracketry or layered assemblies, preventing over-torquing and material damage. With a Rockwell C34 hardness and 160,000 psi tensile strength, it withstands extreme mechanical stresses, making it a trusted choice for high-strength fastening in demanding engineering projects.

Specification Summary & Compliance

This screw adheres to Class 3A thread fit tolerances per UNF standards, ensuring precise engagement and reliability. It meets NAS1801-3-16 specifications for aerospace-grade fasteners and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its environmental safety and suitability for global industrial use.
