S-93406A290 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments
• Superior sheet metal grip through thread-forming design that creates strong, permanent threads without pre-tapping
• Wide truss head distribution provides enhanced load-bearing surface area for secure fastening and reduced material stress
• Optimized Phillips No. 3 drive delivers efficient installation torque transfer while minimizing cam-out risks
• Precision thread engagement with 0.216" diameter and 11 TPI configuration ensures consistent performance in sheet metal up to 0.025" thickness
• Streamlined installation process requiring only a 3/16" drill bit, reducing preparation time and tooling complexity
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

This No. 12 x 1/2" truss head tapping screw delivers exceptional engineering value in sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides inherent corrosion resistance that prevents degradation in demanding environments, while the thread-forming A/AB tapping screw design eliminates the need for separate tapping operations - significantly reducing installation time and labor costs. The wide truss head profile distributes clamping force over a larger surface area, preventing pull-through in thin-gauge materials and maintaining joint integrity under vibration. With full threading and pointed tip configuration, these Phillips drive screws achieve rapid penetration and secure fastening in sheet metal applications up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and automotive panels where reliability and efficiency are paramount.
