S-90485A428 Length 5 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in various environments.
• Efficient thread forming using TRS design creates strong, reliable threads in plastic materials without pre-tapping.
• Secure flush mounting with standard flat head profile and 90° countersink angle for clean, professional finishes.
• Optimized drive engagement with Phillips No. 1 drive size prevents cam-out and ensures consistent installation torque.
• Full threading coverage along the 5mm length provides maximum grip and holding power in plastic applications.
• Environmental compliance with RoHS 3 and REACH regulations ensures safe use in regulated industries.
• Precision metric sizing at M2.5 diameter with 1.12mm pitch for exact fit in international assembly specifications.

Professional Applications & Engineering Value

These M2.5 tapping screws are specifically engineered to address common challenges in plastic fastening applications, where traditional fasteners often cause material cracking or stripping. The 18-8 stainless steel composition provides excellent corrosion resistance while maintaining sufficient hardness for thread forming operations. The TRS thread forming design displaces plastic material rather than cutting it, creating stronger threads with reduced stress concentration. This is particularly valuable in plastic assembly where vibration resistance and pull-out strength are critical. The Phillips flat head configuration with 90° countersink ensures flush mounting in thermoplastic and thermoset materials, making these screws ideal for electronics enclosures, automotive trim, and consumer products where aesthetics and reliability are equally important.

Specification Summary & Compliance

These metric M2.5 x 5mm tapping screws feature standard thread forming (TRS) design with fully threaded shank and blunt tip. The screws maintain precise dimensional accuracy with 4.7mm head diameter and 1.7mm head height for consistent performance. Manufactured to industry standards for plastic fastening applications with recommended No. 45 drill bit (0.082") for optimal thread engagement. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use across multiple sectors.
