S-90380A202 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread retention in plastics thanks to the tri-lobe shank design that forms durable, high-strength threads without pre-tapping.
• Enhanced corrosion resistance from the zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
• Efficient, high-torque installation with the No. 2 Phillips drive, reducing cam-out and speeding up assembly processes.
• Secure and flush fastening achieved with the standard pan head profile, providing a low-profile finish on plastic surfaces.
• Optimized for plastic materials with a 0.164" thread diameter and 16 TPI, designed to prevent material cracking and ensure a tight hold.
• Full-length threading for consistent grip along the entire 1" length, maximizing pull-out strength in plastic applications.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industries and export markets.

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are engineered to solve common fastening challenges in plastic materials, where traditional screws can cause stripping or stress cracking. The thread forming (Type TRS) action of the tri-lobe shank displaces material to create strong, permanent internal threads without generating chips, making them ideal for electronics enclosures, automotive plastic components, and consumer appliances. The Phillips drive ensures reliable torque transfer during installation, while the blunt tip and precise 0.164" thread diameter help align the screw accurately in pre-drilled holes (recommended drill bit: No. 23). This design minimizes assembly time and enhances joint integrity, providing a cost-effective solution for high-volume industrial applications requiring durable, vibration-resistant fasteners.
