S-90627A135 Length 1 1/4" ASME B18.6.3 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black zinc-plated steel construction for extended service life in harsh environments
• Efficient thread-forming design creates strong, permanent threads in plastic materials without pre-tapping
• Optimized for plastic applications with blunt tip to prevent material cracking and ensure secure fastening
• Reliable drive engagement through No. 2 Phillips pan head for consistent torque application and reduced cam-out
• Full threading coverage along the 1-1/4" length provides maximum holding power and uniform stress distribution
• Industry-standard compliance with ASME B18.6.3 ensures consistent quality and interchangeability
• Precision sizing at No. 10 diameter with 16 TPI for optimal thread engagement in plastic components

Professional Applications & Engineering Value

These thread-forming tapping screws are specifically engineered for plastic applications where traditional fastening methods often fail. The black zinc-plated steel construction provides essential corrosion protection while maintaining the mechanical strength required for industrial environments. The DST thread-forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs. The blunt tip prevents material splitting in brittle plastics, while the fully threaded configuration ensures maximum pull-out resistance. These Phillips pan head screws are ideal for automotive trim, electronic enclosures, and construction applications where reliable plastic-to-plastic or plastic-to-metal fastening is critical. The standardized No. 10 size with 16 TPI provides optimal thread engagement without compromising material integrity.

Specification Summary & Compliance

These tapping screws feature precision thread forming with right-hand direction and fully threaded 1-1/4" length. The No. 10 diameter with 16 threads per inch maintains consistent engagement in plastic materials. Manufactured to exacting ASME B18.6.3 standards, these screws ensure dimensional accuracy and reliable performance. The black zinc-plated surface treatment provides enhanced corrosion resistance while maintaining the mechanical properties of steel. The Phillips No. 2 drive and standard pan head design (0.322" diameter, 0.115" height) ensure compatibility with standard driving tools and consistent installation torque.
