S-90190A020 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming capability creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimized for thin materials with maximum 0.025" drilling thickness capability for precise sheet metal applications
• Enhanced driving efficiency through Phillips No. 0 drive design that prevents cam-out and ensures secure installation
• Maximum thread engagement with fully threaded design and pointed tip for quick starting and superior holding power
• Precision 52 TPI threading delivers fine thread pitch for superior grip and vibration resistance in sheet metal assemblies
• Environmental compliance assurance with RoHS 3 certification for safe use in regulated industries and global markets

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered to address common challenges in sheet metal fabrication and assembly operations. The thread forming A/AB type design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, reliable threads that won't strip under vibration. The fully threaded configuration with pointed tip ensures immediate engagement and maximum thread contact throughout the material thickness, providing exceptional pull-out resistance in thin-gauge metals. The pan head style with Phillips drive offers a low-profile fastener head that sits flush while maintaining excellent torque transmission during installation. These characteristics make these industrial screws ideal for HVAC systems, electronic enclosures, automotive components, and other precision sheet metal applications where reliable, vibration-resistant fastening is critical.

Specification Summary & Compliance

These precision tapping screws feature a 0.06" thread diameter with 52 TPI fine threading and Class 2A thread tolerances for consistent performance. The No. 0 x 1/4" size configuration is optimized for use with No. 55 drill bit (0.052" diameter) in sheet metal applications up to 0.025" thickness. Manufactured to industry standards for thread forming screws, these fasteners are fully RoHS 3 (2015/863/EU) Compliant, ensuring they meet stringent environmental regulations for hazardous substance restrictions in electronic and industrial applications.
