S-90054A299 Length 1 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
• Exceptional holding power through thread forming technology that creates strong, permanent threads in sheet metal without pre-tapping
• Enhanced installation efficiency with external hex/slotted drive for secure tool engagement and reduced installation time
• Increased load distribution from the integrated flange design that prevents pull-through and provides superior clamping force
• Optimized thread engagement with 11 TPI and 0.216" diameter threads designed specifically for sheet metal applications
• Full-length threading ensures maximum grip along the entire 1-1/2" length for superior fastening security
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger, more reliable connections. The hex head with external drive provides superior torque transmission during installation, preventing cam-out and ensuring proper seating. The flanged design distributes clamping force evenly, preventing material distortion in thin-gauge metals. Engineered for industrial durability, these screws maintain integrity in demanding environments while the zinc plating offers reliable corrosion protection, making them ideal for HVAC systems, electrical enclosures, and metal fabrication projects where long-term performance is essential.
