• Reliable driving performance with Phillips No. 0 drive that reduces cam-out and ensures secure fastening
• Optimized for plastic applications with 0.67mm thread pitch providing maximum pull-out resistance
• Simplified installation process using standard 1.2mm drill bits for consistent, accurate hole preparation
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for industrial safety standards

Professional Applications & Engineering Value

These M1.6 x 4mm zinc-plated steel tapping screws are specifically engineered for plastic fastening applications where material integrity and secure connections are critical. The thread-forming TRS design eliminates the need for pre-tapped threads by displacing plastic material to create strong, permanent mating threads that resist vibration loosening. The Phillips flat head configuration ensures flush mounting in countersunk holes, providing clean aesthetics while the fully threaded shank maximizes engagement depth for superior pull-out strength. Ideal for electronics enclosures, automotive plastic components, and consumer products, these metric screws deliver reliable performance in demanding industrial environments where material stripping and fastener failure are common concerns.

Specification Summary & Compliance

Manufactured to precise metric dimensions with M1.6 screw size and 4mm length, these fully threaded screws feature standard 0.67mm thread pitch and require 1.2mm drill bits for proper installation. The zinc-plated steel construction provides durable corrosion protection while maintaining the strength needed for plastic applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and industrial suitability for global manufacturing requirements.
