S-99461A209 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Excellent holding power in plastic through advanced thread forming technology that creates strong, permanent threads without pre-tapping
• Reduced installation torque and material stress thanks to the tri-lobe shank design that minimizes radial forces during insertion
• Reliable Phillips drive engagement with No. 1 drive size for secure fastening and reduced cam-out during installation
• Optimal thread engagement with fully threaded 1-1/4" length and 20 TPI configuration for maximum pull-out resistance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industrial applications
• Simplified installation process with compatible No. 37 drill bit size recommendation for precise hole preparation

Professional Applications & Engineering Value

These 18-8 stainless steel TRS tapping screws are specifically engineered for plastic fastening applications where material integrity and long-term performance are critical. The thread forming technology creates strong, permanent threads in plastic substrates without generating chips or debris, eliminating contamination concerns in sensitive assemblies. The tri-lobe shank cross-section significantly reduces installation torque while maintaining exceptional pull-out strength, preventing material stress cracks and deformation common in plastic components. The Phillips drive system with No. 1 drive size ensures reliable torque transmission during high-volume assembly operations. These tapping screws for plastic provide engineering solutions for electronics enclosures, automotive trim, consumer products, and industrial equipment where vibration resistance and environmental durability are essential requirements.
