S-90203A530 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Efficient self-drilling capability eliminates pre-drilling steps, saving time and labor costs in steel, stainless steel, and sheet metal applications
• Superior corrosion resistance with 410 stainless steel construction ensures long-lasting performance in demanding industrial environments
• High-strength thread forming design with 14 TPI creates secure, vibration-resistant fastenings in materials up to 0.21" thick
• Optimized drill tip geometry (No. 3 tip type, 5/16" length) provides clean, precise holes and reliable seating in various metal substrates
• Secure square drive (No. 3) delivers maximum torque transfer and prevents cam-out during installation
• Fully threaded shank ensures consistent holding power along the entire 1" length for uniform clamping force
• Compliant with RoHS 3 and REACH regulations meeting international environmental and safety standards for industrial use

Professional Applications & Engineering Value

These No. 14 self-drilling tapping screws in 410 stainless steel are engineered to solve critical fastening challenges in metal fabrication and construction. The combination of thread forming design and integrated drilling tip eliminates the need for separate drilling operations, significantly reducing installation time while maintaining structural integrity. The pan head with square drive provides excellent torque transmission for secure fastening in steel, stainless steel, and sheet metal applications. The fully threaded configuration ensures maximum thread engagement and pull-out resistance, making these screws ideal for HVAC systems, metal building construction, and industrial equipment assembly where vibration resistance and corrosion protection are essential.

Specification Summary & Compliance

These self-drilling tapping screws feature precise inch measurements with 0.242" thread diameter and 14 TPI thread forming design following BSD standards. The 1" length and fully threaded configuration provide consistent performance across the fastener. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial durability. The right-hand thread direction and standard pan head profile maintain compatibility with conventional installation tools and practices.
