S-90485A431 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 humid or demanding environments
• Efficient thread-forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and labor costs
• Optimal flush mounting with standard 90° flat head profile and No. 1 Phillips drive for clean finishes and secure fastening in plastic applications
• Enhanced driving performance through fully threaded M2.5 design with 1.12mm pitch, providing maximum holding power and vibration resistance
• Precision compatibility with recommended No. 45 drill bit (0.082") for perfect fit and reduced material stress during installation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use across various industrial sectors
• Versatile plastic fastening solution with 8mm length and blunt tip design that prevents material damage while maintaining secure connections

Professional Applications & Engineering Value

These M2.5 TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications, where traditional fastening methods often lead to material cracking or stripped threads. The 18-8 stainless steel composition provides excellent corrosion resistance for outdoor equipment, electronic enclosures, and automotive components exposed to environmental elements. The thread-forming TRS design displaces plastic material rather than removing it, creating stronger thread engagement that resists loosening under vibration - a critical advantage in machinery and consumer electronics. The Phillips flat head with 90° countersink ensures flush mounting that won't interfere with moving parts while the fully threaded shank maximizes pull-out strength in various plastic densities from ABS to polycarbonate.

Specification Summary & Compliance

These metric M2.5 x 8mm tapping screws feature standard thread forming (TRS) design with right-hand threading and 1.12mm approximate pitch. The flat head profile includes a 90° countersink angle with 4.7mm head diameter and 1.7mm head height, compatible with No. 1 Phillips drive. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial durability. Recommended drill bit size No. 45 (0.082") ensures proper fit for plastic applications requiring secure, vibration-resistant fastening solutions.
