S-90385A145 Length 5/16" ASME B18.6.3 Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention with thread-forming DST design that creates strong, permanent threads without chipping or cracking materials
• Enhanced corrosion resistance through zinc-plated steel construction for long-term reliability in various environments
• Optimized installation efficiency with Phillips No. 2 drive that provides excellent torque transfer and prevents cam-out
• Secure fastening performance featuring fully threaded design and blunt tip for maximum holding power in plastic assemblies
• Precision compatibility with No. 35 drill bit (0.11" diameter) for perfect hole preparation and optimal thread formation
• Reduced assembly stress through rounded pan head design that distributes clamping force evenly across plastic surfaces
• Industry-standard reliability meeting ASME B18.6.3 specifications for consistent quality and performance

Professional Applications & Engineering Value

These No. 6-32 thread forming screws are specifically engineered for plastic assembly applications where traditional cutting screws may cause material stress or failure. The DST thread forming technology displaces plastic material during installation, creating strong, load-bearing threads that significantly improve pull-out resistance compared to standard fasteners. The zinc-plated steel construction provides essential corrosion protection while maintaining the necessary strength for demanding plastic fastening scenarios. With their fully threaded design and blunt tip configuration, these screws eliminate the need for pilot holes in many applications, reducing assembly time and labor costs. The Phillips No. 2 drive system ensures reliable installation torque transfer, making them ideal for high-volume production environments where consistency and reliability are paramount.

Specification Summary & Compliance

This thread forming screw features a No. 6-32 thread size with 5/16" length, manufactured to Class 2A thread tolerances for precise fit and performance. The product fully complies with ASME B18.6.3 standards for dimensional accuracy and mechanical properties, ensuring interchangeability and reliability across industrial applications. Environmental compliance is maintained through RoHS 3 (2015/863/EU) certification, making these screws suitable for use in regulated industries and environmentally conscious manufacturing processes. The combination of inch system measurements and standardized thread geometry guarantees consistent performance in North American and international markets where inch-based fasteners are specified.
