S-90485A411 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 chemically exposed environments
• Efficient thread forming design with TRS type profile creates strong, permanent threads in plastic materials without pre-tapping
• Precise 90° countersink angle allows for flush mounting and clean aesthetic finish in plastic assemblies
• Optimized for plastic applications with blunt tip design to prevent material cracking during installation
• Reliable drive engagement with Phillips No. 0 drive size provides secure torque transmission and reduces cam-out risk
• Full threading along 5mm length ensures maximum grip strength and uniform stress distribution in plastic components
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These M1.6 x 5mm Phillips flat head tapping screws deliver exceptional engineering value in plastic assembly applications where material integrity is critical. The 18-8 stainless steel construction provides excellent corrosion resistance, making them ideal for electronics enclosures, automotive interior components, and outdoor equipment where environmental exposure is a concern. The TRS thread forming design eliminates the need for separate tapping operations, reducing assembly time and costs while creating strong, vibration-resistant connections in thermoplastic materials. The 0.67mm thread pitch and fully threaded shank ensure maximum holding power in brittle plastics without causing stress cracking. With their standard flat head profile and 90° countersink angle, these screws provide clean, flush finishes that meet aesthetic requirements in consumer products and industrial equipment alike.

Specification Summary & Compliance

These metric tapping screws feature M1.6 diameter with 5mm length and fully threaded configuration with approximate 0.67mm thread pitch. The TRS type thread forming design is optimized for use with No. 55 drill bit (0.052" diameter) in plastic materials. Manufactured to precise dimensional standards with right-hand threading and standard flat head profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for restricted substance control.
