S-90096A355 3/8"-16 x 3 1/2" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Excellent thread-cutting performance in aluminum, brass, cast iron, and sheet metal without requiring pre-tapped holes
• Enhanced driving torque capability with external hex head design for secure installation and removal
• Increased bearing surface area through integrated flange design for better load distribution and reduced surface damage
• Maximum thread engagement with full threading along the entire 3½" length for superior holding power
• Reliable coarse thread design (UNC 3/8"-16) providing faster installation and reduced cross-threading risks
• Industry compliance assurance meeting ASME B18.6.3 specifications and RoHS 3 environmental standards

Professional Applications & Engineering Value

These Type F thread cutting screws are engineered specifically for challenging metal fabrication and assembly applications. The zinc-plated steel construction provides essential corrosion protection while maintaining the high tensile strength required for structural fastening. The coarse UNC thread profile combined with specialized cutting geometry allows these tapping screws to form precise mating threads in aluminum, brass, cast iron, and sheet metal substrates without pre-tapping operations. This eliminates the need for separate tapping tools and reduces assembly time significantly. The external hex drive and flange design work in tandem to provide superior torque transmission during installation while distributing clamp load over a wider surface area, preventing material deformation in thinner gauge metals commonly used in industrial equipment and structural frameworks.

Specification Summary & Compliance

These 3/8"-16 UNC thread cutting screws feature precise dimensional accuracy with a 0.375" thread diameter and coarse thread spacing for optimal performance in various metal substrates. Manufactured to meet ASME B18.6.3 specifications SAE J933, ensuring consistent quality and performance. The product is fully RoHS 3 (2015/863/EU) compliant for environmental safety and regulatory acceptance in global markets. Designed as Type F tapping screws with blunt tip and fully threaded shank for maximum thread engagement in recommended materials including aluminum, brass, cast iron, and sheet metal applications.
