S-90627A121 Length 1" 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 industrial environments
• Enhanced thread engagement through DST thread forming design creates strong, permanent fastening in plastic materials
• Optimized drive efficiency with No. 2 Phillips head providing reliable torque transmission and reduced cam-out risk
• Complete material penetration with fully threaded design ensuring maximum holding power across the entire screw length
• Reduced installation damage thanks to blunt tip design that minimizes plastic cracking during assembly
• Industry-standard compatibility meeting ASME B18.6.3 specifications for consistent performance and interchangeability
• Simplified installation process with pre-determined No. 35 drill bit size for precise hole preparation

Professional Applications & Engineering Value

This thread forming screw delivers exceptional value in plastic assembly applications where material integrity is paramount. The DST thread forming technology displaces plastic material rather than cutting it, creating zero chips and producing stronger, more vibration-resistant threads. The black zinc-plated steel construction provides essential corrosion protection while maintaining the high-strength characteristics required for demanding industrial environments. With its fully threaded design and 19 TPI right-hand thread configuration, this fastener ensures maximum engagement depth and superior pull-out resistance in thermoplastic and thermoset materials. The Phillips pan head offers a balanced combination of driving efficiency and moderate low-profile appearance, making it ideal for electronics enclosures, automotive components, and consumer products where reliable plastic fastening is critical.

Specification Summary & Compliance

This No. 6 x 1" tapping screw features precision thread forming with standard thread tolerances and complies with ASME B18.6.3 manufacturing specifications. The fastener maintains dimensional accuracy with 0.138" thread diameter, 19 threads per inch, and is designed for use with No. 35 drill bit (0.11" diameter). The black zinc plating surface treatment meets industry standards for corrosion protection while the right-hand thread direction and fully threaded configuration ensure consistent performance across plastic assembly applications.
