S-90275A833 10-32 x 1" ASME B18.6.3 Steel Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding environments
• Exceptional tensile strength of 60,000 psi provides reliable fastening under high-stress conditions without failure
• Precision Class 2A thread fit guarantees smooth installation and consistent engagement in mating components
• 82° countersink angle with standard flat head profile enables flush mounting for streamlined assemblies and improved aesthetics
• Rockwell B70 hardness rating maintains thread integrity and prevents stripping during repeated installations
• Fully threaded right-hand design offers maximum grip length and uniform load distribution across the entire fastener
• Comprehensive compliance with ASME B18.6.3, RoHS 3, and REACH ensures material safety and manufacturing consistency

Professional Applications & Engineering Value

These 10-32 UNF flat head screws deliver critical performance advantages in precision assembly applications where surface flushness and material compatibility are paramount. The zinc-plated steel construction provides essential corrosion protection for industrial equipment, electronic enclosures, and machinery components exposed to moderate environmental conditions. The fine UNF threads with Class 2A fit ensure vibration resistance and prevent loosening in dynamic applications, while the 82° countersink angle creates seamless transitions in pre-drilled surfaces. With 60,000 psi tensile strength and Rockwell B70 hardness, these fully threaded screws maintain structural integrity in high-stress fastening scenarios, making them ideal for automotive, aerospace, and precision manufacturing applications requiring reliable, compliant fastening solutions.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent mating performance. The UNF fine thread (10-32) with right-hand direction and full threading provides standardized engagement. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety and material restrictions. The inch system measurements ensure compatibility with North American equipment and tooling standards.
