S-90485A340 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or demanding environments.
• Efficient thread forming in plastics due to the Tri-Lobe shank design, which reduces driving torque and prevents material stress cracking.
• Secure and flush installation with a standard 82° flat head profile, allowing for a smooth, countersunk finish in plastic assemblies.
• Enhanced drive stability provided by the Phillips No. 2 drive, minimizing cam-out and ensuring consistent fastening performance.
• Full-length threading for maximum grip and holding power across the entire 3/4" length in plastic applications.
• Environmental compliance assurance with RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.
• Precision fit and reduced preparation time with compatibility for a No. 21 drill bit (0.159" diameter), streamlining the installation process.

Professional Applications & Engineering Value

This No. 10 TRS tapping screw is expertly engineered for plastic fastening applications, where its 18-8 stainless steel material offers excellent resistance to oxidation and chemical exposure. The thread forming capability, enhanced by the Tri-Lobe shank cross-section, displaces plastic material without cutting, creating strong, reusable threads that resist loosening under vibration. This design is ideal for electronics enclosures, automotive plastic components, and consumer goods, where Phillips flat head drive ensures a clean, flush finish. By minimizing the risk of plastic cracking and providing consistent right-hand thread engagement, it reduces assembly errors and boosts production line efficiency in industrial settings.

Specification Summary & Compliance

This fastener adheres to inch system measurements with a No. 10 screw size, 3/4" length, and 14 threads per inch for precise fit. It features a standard flat head with an 82° countersink angle and blunt tip for controlled insertion. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global supply chains.
