S-99461A928 Length 5 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or demanding environments.
• Efficient thread forming design eliminates the need for pre-tapped holes, reducing assembly time and labor costs in plastic components.
• Secure Phillips drive engagement with No. 1 drive size for reliable torque transmission and reduced risk of cam-out during installation.
• Optimized pan head profile provides a low-profile, rounded finish that sits flush against surfaces without snagging or damaging materials.
• Full threading along the 5mm length maximizes grip and holding power in plastic substrates for vibration-resistant connections.
• Precision M2.5 metric sizing with consistent 1.12mm pitch ensures exact fit and repeatable performance in standardized applications.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and suitability for global industrial supply chains.

Professional Applications & Engineering Value

This M2.5 TRS tapping screw is specifically engineered for plastic fastening applications where material integrity and assembly efficiency are critical. The thread forming technology displaces plastic material during installation, creating strong, permanent threads without chips or debris. Made from 18-8 stainless steel, it resists oxidation and chemical exposure, making it ideal for electronics enclosures, automotive trim, and consumer appliances. The Phillips pan head design offers a balanced combination of drive stability and aesthetic finish, while the fully threaded shank ensures uniform stress distribution to prevent cracking in brittle plastics. Engineers value its compatibility with standard No. 45 drill bits (0.082"), streamlining production processes and reducing tooling inventory.

Specification Summary & Compliance

This metric thread forming screw features M2.5 diameter with 1.12mm approximate pitch and 5mm length, manufactured to precise dimensional tolerances for consistent performance. The TRS (Thread Rolling Screw) design complies with industry standards for thread-forming fasteners in plastics. It is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting stringent environmental regulations for hazardous substance restrictions. The blunt tip and rounded pan head profile enhance safety and usability in automated or manual assembly lines.
