S-93406A405 Length 7/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Enhanced load distribution thanks to the wide truss head design that prevents pull-through in thin materials
• Efficient thread forming capability creates strong, permanent threads without pre-tapping in sheet metal up to 0.025" thick
• Optimal driving efficiency with No. 2 Phillips drive for secure tool engagement and reduced cam-out
• Maximum holding power through fully threaded design that provides consistent grip along the entire fastener length
• Precise installation guidance with recommended No. 29 drill bit size for proper hole preparation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

This 18-8 stainless steel tapping screw delivers exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The wide truss head provides superior clamping force distribution, preventing material deformation in thin-gauge applications up to 0.025" thickness. The fully threaded No. 8-15 configuration ensures maximum engagement in various material thicknesses, while the Phillips drive system offers familiar, efficient installation for production line environments. These tapping screws are particularly valuable in HVAC systems, electronic enclosures, and automotive components where corrosion resistance and reliable fastening are critical.
