S-96817A547 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in industrial environments.
• Enhanced torque transmission and reduced cam-out with Torx Plus IP20 drive, allowing for precise installation and minimizing tool slippage.
• Secure, vibration-resistant fastening in plastic materials through thread forming technology that creates strong, lasting threads without pre-tapping.
• Full threading along the 12mm length provides maximum grip and uniform stress distribution for consistent holding power.
• Blunt tip design prevents damage to plastic components during installation, maintaining material integrity.
• Compatibility with standard No. 27 drill bits simplifies hole preparation, speeding up assembly processes.
• Pan head style with rounded profile offers a low-profile finish and even clamping force for a neat appearance.

Professional Applications & Engineering Value

This M4.5 TRS tapping screw is engineered specifically for plastic fastening applications, where traditional screws may strip or fail. The thread forming design displaces material to form durable internal threads, eliminating the need for inserts and reducing assembly steps. Made from zinc-plated steel, it resists rust in humid or demanding conditions, while the Torx Plus IP20 drive ensures high torque transfer with minimal wear on tools. Ideal for electronics enclosures, automotive plastic components, and consumer goods, this screw enhances assembly efficiency and reduces maintenance costs by providing reliable, long-lasting connections without compromising plastic integrity.

Specification Summary & Compliance

This metric screw features an M4.5 size with an approximate thread pitch of 1.63 mm, fully threaded for consistent performance. It complies with standard dimensional tolerances for thread forming screws and is designed for use with a No. 27 drill bit (0.144" diameter). The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial and consumer applications.
