S-90380A261 Length 3/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastics thanks to the Tri-Lobe shank cross-section that displaces material to create durable, vibration-resistant threads
• Reliable corrosion resistance provided by the zinc-plated steel construction, extending the service life of your plastic assemblies
• Efficient, high-torque installation enabled by the Phillips No. 1 drive, reducing the risk of cam-out and tool slippage
• Reduced risk of plastic cracking due to the thread-forming (TRS) tapping method, which forms threads without cutting and removing material
• Consistent and full engagement along the entire 3/16" length with fully threaded design for maximum fastening strength
• Precise 28 TPI thread pitch ensures a tight, secure fit in plastic components, minimizing loosening under stress
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring they are safe for use in regulated industries

Professional Applications & Engineering Value

These No. 2 x 3/16" zinc-plated steel TRS tapping screws are engineered specifically for plastic assembly challenges. The thread-forming technology and unique Tri-Lobe shank design solve the common problem of stripped threads and material failure by cold-forming strong, permanent mating threads in plastic substrates. This creates a far more reliable connection than standard machine screws, effectively resisting vibrational loosening. The blunt tip and precise 0.086" thread diameter allow for easy starting and alignment, speeding up production while the zinc plating provides a protective barrier against corrosion in various industrial environments. Ideal for electronics enclosures, automotive trim, and consumer goods.
