S-90380A319 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the tri-lobe shank design that displaces material to create permanent, vibration-resistant threads
• Corrosion-resistant zinc-plated steel construction ensures long-term durability and reliability in various industrial environments
• Efficient thread-forming installation eliminates the need for pre-tapped holes, reducing assembly time and labor costs
• Secure #3 Phillips drive system provides excellent torque transfer and prevents cam-out during installation for consistent fastening
• Full 2-inch threading length offers maximum engagement depth for strong, reliable connections in plastic assemblies
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets international manufacturing standards
• Standard pan head design provides a low-profile finish with good bearing surface for secure fastening applications

Professional Applications & Engineering Value

These 1/4" zinc-plated steel TRS tapping screws deliver exceptional performance in plastic fastening applications where traditional threaded fasteners may fail. The innovative tri-lobe shank cross-section and thread forming technology solve critical engineering challenges by creating strong, permanent threads in plastic substrates without tapping operations. This eliminates strip-out issues and provides superior resistance to vibration loosening. The #3 Phillips drive ensures reliable installation with standard tools, while the zinc-plated surface treatment protects against corrosion in demanding industrial environments. These thread forming screws are engineered specifically for plastic assembly applications where high pull-out strength and long-term reliability are essential requirements.

Specification Summary & Compliance

These TRS tapping screws feature precise 1/4" thread diameter with 10 threads per inch and right-hand threading throughout the full 2-inch length. Manufactured from zinc-plated steel with a standard pan head profile and #3 Phillips drive, they are designed for use with A drill bit size (0.234" diameter) in plastic materials. The screws maintain tight manufacturing tolerances and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications.
