S-99512A611 Length 3/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T8 Torx drive that prevents cam-out and ensures reliable installation in plastic assemblies
• Excellent corrosion resistance provided by zinc-plated steel construction, extending service life in various industrial environments
• Vibration-resistant fastening achieved through the tri-lobe shank design that creates permanent threads in plastic materials
• Eliminates pre-drilling requirements with thread-forming TRS design, reducing assembly time and labor costs
• Secure plastic-to-plastic fastening with fully threaded No. 2 screw that maintains consistent holding power along the entire 3/16" length
• Reduced material stress during installation thanks to the blunt tip design that minimizes cracking in plastic components
• Industry compliance assurance with RoHS 3 and REACH regulations for safe use in regulated applications

Professional Applications & Engineering Value

This No. 2 plastic tapping screw delivers exceptional engineering value for plastic assembly applications where reliability and efficiency are paramount. The zinc-plated steel construction provides durable corrosion protection while the TRS thread-forming design with tri-lobe shank creates permanent, vibration-resistant threads without requiring pre-tapped holes. The T8 Torx drive system ensures maximum torque transfer during installation, preventing stripping and reducing assembly defects. Engineered specifically for plastic fastening, this screw's right-hand thread and blunt tip minimize material stress and cracking, making it ideal for electronics enclosures, automotive trim, and consumer products where plastic integrity is critical.

Specification Summary & Compliance

This thread forming screw features precision No. 2 thread diameter (0.086") with 28 threads per inch and full threading along the 3/16" length. The TRS (Thread Rolling Screw) design with tri-lobe shank cross-section ensures proper thread formation in plastic materials without pre-drilling when used with the recommended 5/64" drill bit. Manufactured to industry standards for tapping screws, this product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental and safety regulations for industrial applications.
