S-90077A245 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in industrial environments
• Enhanced torque transmission through dual Phillips/Slotted drive design, reducing tool slippage and installation time
• Permanent thread formation in sheet metal without pre-tapping, creating reliable fastening joints that resist vibration loosening
• Quick starting and alignment with pointed tip design, streamlining assembly processes in high-volume production
• Full-length threading maximizes grip range and load distribution across the entire fastener length
• Optimized for 0.025" sheet metal with precise No. 21 drill bit compatibility, ensuring clean installations without material damage
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming technology (Type A/AB) creates precisely mated threads that eliminate the need for separate tapping operations, significantly reducing labor costs and production time. The pan head design with dual Phillips/Slotted drive provides versatile installation options while maintaining a low-profile appearance. Engineered for 0.025" maximum drilling thickness, these fully threaded screws ensure consistent performance in HVAC systems, electrical enclosures, and automotive panels where vibration resistance and environmental compliance are critical. The right-hand threading with 12 threads per inch delivers optimal engagement in various sheet metal thicknesses while the corrosion-resistant zinc plating protects against industrial atmospheric conditions.

Specification Summary & Compliance

This No. 10-12 x 3/4" tapping screw features precision thread forming technology with 0.19" thread diameter and fully threaded design for maximum holding power. Manufactured to industry standards for A/AB tapping screw types with Class 2A thread fit tolerance. The fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global manufacturing applications. Compatible with standard No. 21 drill bits (0.159" diameter) for optimal performance in sheet metal applications up to 0.025" thickness.
