S-90380A282 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various environments
• Efficient thread-forming design with tri-lobe shank, reducing installation torque and preventing material stress in plastics
• Reliable fastening in plastic applications thanks to the TRS type F thread and 20 TPI pitch, minimizing stripping and improving hold
• Easy installation and removal with Phillips No. 2 drive and pan head, allowing for quick assembly without specialized tools
• Consistent thread engagement with fully threaded, right-hand design, providing uniform clamping force and vibration resistance
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in industrial settings
• Optimized for No. 33 drill bits (0.113" diameter), simplifying hole preparation and reducing assembly time

Professional Applications & Engineering Value

These No. 5 x 1/2" zinc-plated steel tapping screws are engineered to address common challenges in plastic fastening, such as material cracking and thread stripping. The TRS thread-forming design with a tri-lobe shank displaces plastic material during installation, creating strong, permanent threads without the need for inserts or adhesives. This reduces assembly steps and enhances joint integrity in applications like electronic enclosures, automotive components, and consumer products. The Phillips drive and pan head ensure secure driving and a low-profile finish, while the zinc-plated surface offers protection against rust, making these screws ideal for both indoor and mildly corrosive environments. By minimizing failure risks and improving efficiency, they deliver reliable engineering value in high-volume manufacturing.

Specification Summary & Compliance

This product adheres to standard inch measurements with precise dimensions, including a thread diameter of 0.125" and length of 1/2". The thread-forming design follows typical industry tolerances for plastic applications, ensuring consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting environmental safety in industrial use.
