S-99461A931 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in various environments
• Efficient thread forming with TRS design creates strong, permanent threads in plastic materials without pre-tapping
• Secure drive engagement through Phillips No. 1 drive style, preventing cam-out and ensuring proper installation torque
• Optimized plastic fastening with blunt tip and fully threaded design to prevent material cracking and ensure uniform stress distribution
• Standard pan head profile provides excellent bearing surface and clean aesthetic finish for assembled components
• Precision metric sizing at M2.5 diameter with 8mm length delivers consistent performance in tight plastic assembly applications
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These M2.5 thread forming screws are specifically engineered for plastic assembly applications where traditional fastening methods often cause material stress or failure. The 18-8 stainless steel construction provides exceptional corrosion resistance, making these TRS tapping screws ideal for electronics enclosures, automotive plastic components, and outdoor equipment where environmental exposure is a concern. The thread forming design displaces plastic material rather than cutting it, creating stronger threads with reduced risk of cracking in brittle plastics. With fully threaded configuration and 1.12mm pitch, these screws distribute clamping force evenly, preventing stress concentration points that can lead to plastic deformation or failure over time. The combination of Phillips No. 1 drive and pan head style ensures reliable installation while maintaining a low-profile appearance suitable for consumer products and industrial equipment alike.

Specification Summary & Compliance

These metric thread forming screws feature M2.5 diameter with 8mm length and standard 1.12mm thread pitch. The TRS (Thread Rolling Screw) design follows industry-standard thread forming principles for plastic materials. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial compliance requirements for hazardous substance restrictions. The screws are designed for use with No. 45 drill bit (0.082" diameter) for proper hole preparation in plastic substrates.
