S-90385A364 Length 5/8" ASME B18.6.3 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Excellent thread-forming capability creates permanent, vibration-resistant threads in plastic materials without pre-tapping
• Optimized drive efficiency with Phillips No. 3 drive for reliable torque transmission and reduced cam-out during installation
• Maximum material engagement through fully threaded design with 15 TPI precision for superior holding power in plastic assemblies
• Reduced installation damage with blunt tip design that displaces material without cutting or creating chips
• Streamlined assembly process with compatible No. 7 drill bit (0.201") sizing for precise hole preparation
• Industry-standard compliance meeting ASME B18.6.3 specifications for consistent quality and performance

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value for plastic assembly applications where vibration resistance and long-term reliability are critical. The thread forming (DST) design eliminates the need for separate tapping operations by displacing plastic material to create strong, permanent threads that won't loosen under stress. The Phillips pan head configuration provides a low-profile finish while the fully threaded shank ensures maximum engagement depth. Engineered specifically for plastic materials, these screws prevent cracking and material failure common with standard fasteners, making them ideal for automotive components, electrical enclosures, and consumer products requiring durable plastic-to-plastic or plastic-to-metal connections.

Specification Summary & Compliance

These No. 14 x 5/8" tapping screws feature precision right-hand threads with 15 TPI and are manufactured to exacting dimensional standards. The screws comply with ASME B18.6.3 specifications for thread forming tapping screws, ensuring consistent quality and performance. The zinc-plated steel construction provides corrosion protection while maintaining the mechanical properties required for industrial applications. All manufacturing processes adhere to industry standards for dimensional accuracy and material integrity.
