S-90063A242 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in industrial environments
• Enhanced torque transmission through the external hex head design, allowing for secure installation with standard tools
• Efficient thread forming with pointed needle tip that creates strong, permanent threads in sheet metal without pre-tapping
• Secure locking capability with serrated flange design that prevents loosening under vibration and provides wider bearing surface
• Optimized for thin materials with maximum drilling thickness of 0.05", making it ideal for various sheet metal applications
• Full thread engagement along the entire 1/2" length ensures maximum holding power and pull-out resistance
• Environmental compliance with RoHS 3 standards, meeting international regulatory requirements for hazardous substances

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are specifically engineered to address common challenges in sheet metal fabrication and assembly. The zinc-plated steel construction provides excellent corrosion protection while maintaining high tensile strength for demanding industrial applications. The external hex drive design enables maximum torque application without stripping, crucial for high-volume production environments. The fully threaded pointed tip with needle profile creates precise, clean threads in materials up to 0.05" thickness, eliminating the need for separate tapping operations and reducing assembly time. The serrated flange provides superior locking action against vibration, making these screws ideal for automotive components, electrical enclosures, HVAC systems, and machinery where reliable fastening is critical.

Specification Summary & Compliance

This flanged tapping screw features precise No. 10-12 thread specifications with 0.19" thread diameter and 12 threads per inch, designed for use with No. 21 drill bit (0.159" diameter). The screw maintains right-hand thread direction with fully threaded shank and 0.414" flange diameter for optimal performance. Manufactured from high-strength zinc-plated steel with external hex/slotted drive combination, these screws comply with RoHS 3 (2015/863/EU) environmental standards, ensuring they meet international regulatory requirements for hazardous substance restrictions in industrial applications.
