S-90627A132 Length 5/8" ASME B18.6.3 Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic fastening performance with thread forming design that creates strong, permanent threads without chips
• Enhanced corrosion resistance through black zinc-plated steel construction for extended service life in industrial environments
• Optimized installation efficiency with Phillips No. 2 drive for secure tool engagement and reduced cam-out
• Maximum holding power achieved through fully threaded design that distributes load evenly along the entire screw length
• Reduced material stress with blunt tip design that minimizes cracking in plastic components during installation
• Precision compatibility with No. 27 drill bit (0.144" diameter) for proper hole preparation and secure fastening
• Reliable industrial performance backed by ASME B18.6.3 specification compliance for consistent quality and dimensional accuracy

Professional Applications & Engineering Value

These #10-16 DST tapping screws are specifically engineered for plastic fastening applications where traditional threaded fasteners may fail. The thread forming design creates strong, permanent mating threads in plastic materials without generating chips that could contaminate sensitive assemblies. The black zinc-plated steel construction provides essential corrosion protection in demanding industrial environments, while the fully threaded, blunt tip configuration minimizes stress concentration points that often lead to plastic cracking. The combination of Phillips drive and precise 5/8" length ensures efficient installation in confined spaces common in plastic component assembly. These thread forming screws deliver reliable performance in automotive trim, electronic enclosures, and consumer products where plastic-to-plastic or plastic-to-metal connections require durable, vibration-resistant fastening solutions.

Specification Summary & Compliance

These tapping screws feature a 0.19" thread diameter with 16 threads per inch in right-hand orientation and 5/8" overall length. Manufactured to ASME B18.6.3 standards, they ensure dimensional accuracy and consistent performance. The DST (Thread Forming) design with blunt tip and fully threaded configuration provides optimal fastening in plastic materials when used with the recommended No. 27 drill bit (0.144" diameter). The black zinc-plated steel construction meets industry requirements for corrosion resistance while maintaining the mechanical properties necessary for reliable plastic assembly applications.
