S-90286A203 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming capability creates permanent, vibration-resistant threads in sheet metal without chips or debris
• Maximum torque transmission through external hex/slotted drive design prevents stripping during high-torque installation
• Flanged head design provides increased bearing surface for better load distribution and eliminates need for separate washers
• Fully threaded shank ensures maximum grip length and consistent holding power throughout the entire fastener
• Pointed tip design enables easy starting and precise alignment in pre-drilled holes using No. 29 drill bit
• Optimized for 0.025" maximum drilling thickness making it ideal for standard sheet metal fabrication applications
• Environmental compliance assurance with RoHS 3 and REACH regulations for global industrial use

Professional Applications & Engineering Value

This No. 8-15 hex head tapping screw delivers exceptional performance in sheet metal applications where reliable fastening is critical. The thread forming design eliminates common issues with traditional tapping screws by creating strong, permanent threads through material displacement rather than cutting. This results in zero chip generation, preventing contamination in sensitive assemblies while providing superior resistance to vibration loosening. The combination of external hex/slotted drive offers installation flexibility for both power tools and manual drivers, while the flanged head distributes clamping force evenly across thinner materials. Engineered specifically for use with No. 29 drill bit (0.136" diameter), this 1-1/2 inch sheet metal screw ensures precise fitment in HVAC systems, electronic enclosures, automotive panels, and industrial equipment where consistent performance and regulatory compliance are mandatory.

Specification Summary & Compliance

This thread forming tapping screw features a No. 8 screw size with 0.164" thread diameter and 15 threads per inch, manufactured to precise dimensional standards for consistent performance. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. Designed as Type A tapping screw with right-hand threading and fully threaded configuration, it meets industrial standards for sheet metal fastening applications requiring maximum drilling thickness of 0.025". The hex head design provides Class 2A thread fit tolerance for reliable engagement in pre-tapped or thread-forming applications.
