S-90190A081 Length 7/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and tooling needs.
• High thread density (32 TPI) provides excellent holding power and vibration resistance in thin materials.
• Optimized for 0.025" maximum drilling thickness in sheet metal applications, preventing material damage and ensuring secure fastening.
• Reliable Phillips drive (No. 1 size) offers common tool compatibility and controlled torque application during installation.
• Fully threaded shank maximizes grip length and pull-out strength across the entire fastener engagement.
• Compliant with RoHS 3 and REACH regulations for safe use in regulated industries and global market acceptance.

Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws deliver exceptional performance in sheet metal assembly applications where material integrity and joint reliability are critical. The thread forming design (A/AB type) displaces material rather than cutting it, creating zero chips and stronger thread engagement that resists loosening under vibration. The pan head profile with Phillips drive provides a low-profile installation while maintaining sufficient drive torque capacity. Engineered for 0.086" thread diameter and 32 TPI thread pitch, these screws achieve optimal balance between material thickness compatibility and fastening strength, making them ideal for electronics enclosures, HVAC components, and automotive panels where thin-gauge metals require secure, permanent fastening solutions.

Specification Summary & Compliance

This No. 2 size tapping screw features a 0.086" thread diameter with 32 threads per inch in right-hand direction and fully threaded configuration. The fastener meets standard dimensional requirements for A/AB type thread forming screws with Class 2A thread fit tolerance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restriction of hazardous substances. Recommended for use with No. 48 drill bit (0.076" diameter) for optimal performance in sheet metal applications up to 0.025" maximum drilling thickness.
