S-90090A247 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without chips or debris
• Secure one-way drive system prevents tampering and unauthorized removal in sensitive applications
• Optimized pan head design provides excellent bearing surface and professional finished appearance
• Precision threading with 12 threads per inch ensures reliable engagement and consistent clamping force
• Full 1" threading maximizes grip range and load distribution across the entire fastener length
• Regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These thread forming tapping screws deliver exceptional value in sheet metal assembly applications where vibration resistance and material integrity are critical. The A/AB screw type with thread forming technology eliminates the need for pre-tapped holes while creating stronger thread engagement through material displacement rather than removal. Manufactured from 18-8 stainless steel, these fasteners maintain their mechanical properties and corrosion resistance even in harsh industrial environments. The combination of right-hand threading and fully threaded design ensures uniform stress distribution, preventing loosening under dynamic loads. Engineered for use with No. 21 drill bits (0.159" diameter), these screws provide reliable performance in materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and automotive components where secure, permanent fastening is essential.

Specification Summary & Compliance

These No. 10-12 thread forming tapping screws feature precision Class 2A thread tolerances with a thread diameter of 0.19" and pan head diameter of 0.359". The A/AB tapping screw type follows industry-standard thread forming specifications for optimal performance in sheet metal applications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmentally responsible manufacturing and chemical safety standards. The screws are designed for use with standard No. 21 drill bits (0.159" diameter) and accommodate maximum drilling thickness of 0.025" in various metalworking applications.
