S-90627A133 Length 3/4" 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 demanding environments
• Excellent vibration resistance through thread forming technology that creates permanent, secure fastening in plastic materials
• Optimized for plastic applications with DST thread design that prevents material cracking and ensures reliable holding power
• Easy installation and removal with No. 2 Phillips drive that provides secure tool engagement and reduces stripping risk
• Full thread engagement along the 3/4" length for maximum pull-out strength and distribution of stress points
• Standardized dimensions with 0.19" thread diameter and 16 TPI for consistent performance and compatibility
• Rounded pan head design that provides a low-profile finish while preventing surface damage during installation

Professional Applications & Engineering Value

This No. 10 DST tapping screw is specifically engineered to address the unique challenges of plastic fastening applications, where traditional fasteners often cause material stress, cracking, or stripping. The thread forming technology creates precise mating threads in plastic substrates without removing material, resulting in superior vibration-resistant fastening that maintains integrity under dynamic loads. The black zinc-plated steel construction provides essential corrosion protection for industrial environments, while the fully threaded design ensures maximum holding power across the entire engagement length. These self-tapping screws eliminate the need for pre-tapped holes, streamlining assembly processes in plastic fabrication, electronic enclosures, automotive components, and consumer products where reliable, permanent fastening is critical.

Specification Summary & Compliance

This tapping screw features precise inch system dimensions including 0.19" thread diameter, 16 TPI thread pitch, and 3/4" length with fully threaded configuration. The screw meets ASME B18.6.3 specifications for dimensional accuracy and performance standards, ensuring consistent quality and reliability. Manufactured from steel with black zinc plating for corrosion protection, it features a standard rounded pan head with No. 2 Phillips drive and is designed for use with No. 27 drill bit (0.144" diameter) in plastic applications. The thread forming (DST) tapping method and right-hand thread direction provide optimal performance in compliance with industrial fastening standards.
