S-99461A949 Length 30 mm Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-tapped holes with thread forming design for faster assembly and reduced labor costs in plastic materials
• Superior corrosion resistance from 18-8 stainless steel construction ensuring long-term reliability in humid or demanding environments
• Optimized drive engagement with Phillips No. 1 drive preventing cam-out and enabling efficient installation with standard tools
• Full-length threading maximizes grip strength and pull-out resistance across the entire 30mm length in plastic substrates
• Precision-engineered pan head with 5.3mm diameter provides secure seating without sinking into softer plastic materials
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing and environmental safety requirements
• Simplified installation process with compatible No. 41 drill bit size (0.096") for precise hole preparation in plastic assemblies

Professional Applications & Engineering Value

These M3 thread forming screws deliver exceptional engineering value in plastic fastening applications where traditional threaded fasteners fail. The TRS thread forming design creates strong, permanent threads in plastic materials through cold flow displacement, eliminating the need for inserts or pre-tapped holes that can weaken the substrate. Manufactured from 18-8 stainless steel, these screws maintain their mechanical integrity while providing excellent resistance to corrosion and chemical exposure common in industrial environments. The Phillips pan head configuration offers a low-profile solution that distributes clamping force effectively across the 5.3mm bearing surface, preventing stress cracking in brittle plastics. With a precise 1.34mm thread pitch and fully threaded 30mm length, these metric tapping screws ensure maximum engagement depth and vibration resistance in electronic enclosures, automotive trim, and consumer product assemblies where reliability is critical.

Specification Summary & Compliance

This M3 x 30mm TRS screw features precision metric thread forming with a 1.34mm thread pitch and fully threaded shank design. The fastener maintains standard dimensional tolerances for thread forming screws in plastic applications and is compatible with No. 41 drill bits (0.096" diameter) for proper hole preparation. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in global markets.
