S-90434A144 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior material protection with zinc plating that resists corrosion, extending service life in various environments.
• Efficient installation in plastics using thread-forming TRS design that creates strong, reliable threads without pre-tapping.
• Optimized drive engagement with Phillips No. 2 drive style providing secure torque transmission and reduced cam-out risk.
• Flush mounting capability thanks to the standard flat head with 90° countersink angle for clean, professional finishes.
• Full-length threading ensures maximum grip and holding power along the entire 12mm length in plastic assemblies.
• Precision compatibility with 3mm drill bits for perfectly sized pilot holes, minimizing installation time and errors.
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing.

Professional Applications & Engineering Value

These M4 TRS tapping screws are specifically engineered for plastic assembly applications where traditional fasteners often fail. The thread-forming design displaces material rather than cutting it, creating zero clearance fits that resist vibration loosening and provide exceptional pull-out strength. Made from zinc-plated steel, these screws offer the ideal balance of corrosion resistance and mechanical strength for demanding environments. The Phillips No. 2 drive combined with the standard flat head profile ensures quick installation with standard tools while maintaining a low-profile appearance. These metric tapping screws solve common plastic fastening challenges including material cracking, strip-out, and inconsistent clamping force, making them ideal for electronics enclosures, automotive trim, and consumer products where reliability is critical.

Specification Summary & Compliance

These fully threaded M4 screws feature a precise 1.79mm pitch with right-hand threading and blunt tip design optimized for plastic materials. The 8.4mm head diameter and 2.9mm head height provide optimal clamping surface while the standard flat head profile with 90° countersink angle ensures proper seating. Manufactured to industry standards for thread-forming tapping screws, these fasteners are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring they meet the latest environmental and safety regulations for industrial use.
