S-99461A202 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Exceptional holding power in plastic due to the tri-lobe shank design that displaces material to create secure, vibration-resistant threads
• Reduced installation torque and cam-out risk with the precise Phillips No. 1 drive for efficient, reliable fastening
• Optimized for plastic assembly with a thread forming (TRS) design that eliminates chips and ensures strong thread engagement
• Full 3/4" length threading provides maximum grip and pull-out strength across the entire fastened joint
• Simplified installation process with compatibility for standard No. 48 drill bits, ensuring proper hole preparation
• Compliance with major environmental regulations including RoHS 3 and REACH for safe, sustainable use in global markets

Professional Applications & Engineering Value

These TRS thread forming screws are engineered specifically for plastic fastening applications, where traditional fasteners often fail. The 18-8 stainless steel provides excellent corrosion resistance, crucial for outdoor enclosures, automotive trim, and electrical components exposed to moisture. The tri-lobe shank cross-section and 28 TPI precision threading work together to cold-form strong, clean mating threads in plastic substrates without creating chips that could cause electrical shorts or mechanical interference. This thread forming method generates radial compressive forces, significantly enhancing resistance to vibrational loosening—a common failure point in assemblies. The Phillips drive offers a familiar and widely accessible installation method, while the blunt tip ensures easy starting and alignment. Ideal for securing plastic housings, panels, and components in electronics, appliances, and construction where material integrity and long-term reliability are paramount.
