S-99461A943 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Optimal torque transfer through Phillips No. 1 drive design, reducing cam-out and improving installation efficiency
• Secure vibration-resistant fastening with fully threaded M3 design and 1.34mm pitch for maximum holding power in plastic
• Prevents material damage with blunt tip and thread forming (TRS) design that displaces rather than cuts plastic material
• Consistent installation performance with standard pan head profile providing reliable clamping force distribution
• Comprehensive regulatory compliance meeting RoHS 3 and REACH standards for global industrial applications
• Precision matching with No. 41 drill bit compatibility for optimal hole preparation in plastic assemblies

Professional Applications & Engineering Value

These M3 tapping screws are specifically engineered for plastic assembly applications where material integrity and connection reliability are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance while the thread forming (TRS) design creates strong, vibration-resistant threads in plastic substrates without creating chips or debris. The fully threaded configuration with 1.34mm pitch ensures maximum engagement and pull-out resistance, while the blunt tip prevents cracking or splitting of delicate plastic components. The Phillips No. 1 drive enables efficient installation with standard tools, making these metric tapping screws ideal for high-volume manufacturing environments requiring consistent, reliable fastening solutions in plastic enclosures, electronic housings, and industrial plastic assemblies.

Specification Summary & Compliance

These M3 x 12mm tapping screws feature metric dimensions with standard thread forming (TRS) design for plastic applications. The screws maintain precise dimensional accuracy with 5.3mm head diameter and 2.1mm head height for consistent performance. Manufactured to industry standards for thread forming screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental and safety requirements for industrial use worldwide. The right-hand threading and standard pan head profile provide reliable, repeatable fastening performance in plastic materials.
