S-90627A142 Length 1" ASME B18.6.3 Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention with thread forming design that creates strong, permanent threads without chips or debris
• Enhanced corrosion resistance through black zinc-plated steel construction for extended service life in industrial environments
• Optimized drive efficiency with Phillips No. 3 drive that prevents cam-out and ensures consistent installation torque
• Maximum thread engagement through fully threaded design that provides superior holding power across the entire fastener length
• Precision installation with blunt tip design that aligns perfectly with No. 7 drill bits (0.201" diameter) for accurate positioning
• Reliable performance standards meeting ASME B18.6.3 specifications for consistent quality and dimensional accuracy
• Versatile application capability with 0.242" thread diameter and 15 TPI configuration ideal for various plastic materials

Professional Applications & Engineering Value

These DST thread forming screws deliver exceptional value in plastic fastening applications where traditional fasteners fail. The thread forming technology eliminates the risk of material cracking or stress concentration common in plastic assemblies by displacing material rather than removing it. The black zinc-plated steel construction provides superior corrosion protection while maintaining the mechanical strength required for demanding industrial environments. With fully threaded design and precise 0.242" thread diameter, these screws distribute clamping force evenly, preventing material deformation and ensuring long-term joint integrity in plastic components across automotive, electronics, and consumer goods manufacturing.

Specification Summary & Compliance

This No. 14 x 1" DST thread forming screw features inch system measurements with 0.242" thread diameter and 15 TPI thread pitch. Manufactured to ASME B18.6.3 specifications, these screws ensure dimensional accuracy and performance reliability. The Phillips No. 3 drive provides standardized installation compatibility, while the fully threaded design with blunt tip optimizes engagement in plastic materials. Compliant with industry standards for mechanical fasteners, these screws are engineered for use with No. 7 drill bits (0.201" diameter) to achieve proper hole preparation and optimal fastening performance.
