S-90380A288 Length 1 1/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials through advanced TRS thread forming design that creates secure, permanent threads without chipping or cracking
• Excellent corrosion resistance provided by zinc-plated steel construction, ensuring long-term reliability in various industrial environments
• Enhanced driving efficiency with Phillips No. 2 drive system that prevents cam-out and allows for consistent torque application
• Optimal material displacement achieved through tri-lobe shank cross-section, reducing installation torque while maintaining exceptional pull-out resistance
• Complete thread engagement with fully threaded 1-1/8" length and 19 TPI configuration for maximum fastening strength throughout the entire connection
• Simplified installation process with standard pan head design that sits flush against surfaces and requires only a 1/8" pilot hole
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in global industrial applications

Professional Applications & Engineering Value

These No. 6 zinc-plated steel tapping screws deliver exceptional engineering value in plastic assembly applications where traditional fastening methods often fail. The specialized TRS thread forming design eliminates the need for pre-tapped holes while preventing stress cracking in brittle plastics - a common challenge in automotive trim, electronic enclosures, and consumer product manufacturing. The tri-lobe shank cross-section strategically displaces plastic material during installation, creating stronger mating threads than the original material while significantly reducing drive torque. Combined with the corrosion-resistant zinc-plated steel construction and reliable Phillips drive system, these screws provide durable, vibration-resistant connections that maintain integrity through thermal cycling and mechanical stress, making them ideal for high-volume production environments requiring consistent performance.

Specification Summary & Compliance

These thread forming screws feature precise No. 6 thread diameter (0.138") with 19 threads per inch configuration and fully threaded 1-1/8" length. Manufactured to exacting standards with Class 2A thread tolerances, the screws incorporate TRS thread forming technology with tri-lobe shank design for optimal performance in plastic substrates. The product fully complies with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, ensuring environmental responsibility and workplace safety compliance for industrial applications worldwide.
