S-90056A242 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Excellent holding power through thread forming technology that creates strong, permanent threads in sheet metal without pre-tapping
• Optimized installation efficiency with Phillips No. 2 drive and pan head design for secure tool engagement and reduced cam-out
• Complete material engagement with fully threaded design ensuring maximum grip along the entire fastener length
• Precision blunt tip design for easier starting and reduced material displacement during installation
• Industry-standard compatibility with No. 21 drill bit (0.159" diameter) for simplified hole preparation
• Environmental compliance assurance meeting RoHS 3 standards for safe, regulated manufacturing

Professional Applications & Engineering Value

Engineered specifically for sheet metal applications, these No. 10-16 thread forming screws deliver exceptional performance where traditional fasteners fail. The zinc-plated steel construction provides reliable corrosion protection in industrial settings, while the thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs. The Phillips drive system ensures secure tool engagement during high-torque applications, minimizing stripping and cam-out issues. With fully threaded blunt tip design, these tapping screws create strong, permanent threads in metal substrates without chip formation, making them ideal for HVAC systems, electrical enclosures, automotive assemblies, and construction projects where vibration resistance and long-term reliability are critical.
