S-90190A294 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Exceptional holding power through thread forming technology that creates strong, permanent threads in sheet metal without pre-tapping
• Optimized drive efficiency with No. 3 Phillips head design for secure tool engagement and reduced cam-out during installation
• Maximum thread engagement with fully threaded 3/4" length and 11 TPI design for superior pull-out resistance in thin materials
• Reliable material compatibility with A/AB thread forming specifications, ideal for various sheet metal thicknesses up to 0.025"
• Enhanced installation control featuring pointed tip for precise starting and pan head design for consistent flush seating
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

This No. 12 x 3/4" zinc-plated steel tapping screw delivers exceptional engineering value for sheet metal fastening applications where vibration resistance and permanent installation are critical. The thread forming technology eliminates the need for pre-tapped holes, reducing installation time while creating stronger, more durable threads that won't strip under stress. The Phillips pan head design provides reliable drive transfer and sits flush against surfaces, making it ideal for HVAC systems, electrical enclosures, and metal fabrication where corrosion resistance is essential. The combination of 0.216" thread diameter and 11 threads per inch ensures maximum holding power in materials up to 0.025" thickness, solving common challenges with thin metal fastening where traditional screws may fail.

Specification Summary & Compliance

This thread forming sheet metal fastener features precise 0.216" thread diameter with 11 threads per inch and 3/4" fully threaded length. Manufactured to A/AB tapping screw standards with Class 2A thread tolerances for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety for industrial applications worldwide.
