- Exceptional holding power from the fully threaded BSD thread forming design, which creates strong, secure fastenings in steel and sheet metal.
- Reliable drive engagement provided by the square drive style, reducing cam-out and ensuring precise installation torque.
- Optimized for high-volume applications with a pan head and standard rounded profile for consistent seating and a finished appearance.
- Compliance with major environmental regulations including RoHS 3 and REACH, ensuring suitability for global supply chains and sensitive applications.
Professional Applications & Engineering Value
This No. 8-18 x 1/2" 410 Stainless Steel Tapping Screw is engineered to solve critical fastening challenges in steel, stainless steel, and sheet metal assemblies. Its BSD thread forming technology and self-drilling tip eliminate the need for separate drilling and tapping operations, significantly reducing labor and potential alignment errors. The fully threaded design ensures maximum thread engagement along the entire shank, providing superior resistance to vibration loosening and pull-out forces. Manufactured from durable 410 stainless steel, it offers excellent strength and corrosion resistance, making it ideal for HVAC, automotive, and electrical enclosure applications where reliability and regulatory compliance are paramount.
Specification Summary & Compliance
This screw conforms to standard inch measurements with a No. 8-18 thread and 1/2" length, featuring a right-hand thread direction and fully threaded shank. The pan head with square drive (No. 2) ensures secure torque application. It is manufactured to precise dimensional standards for consistent performance and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
