Professional Applications & Engineering Value

These Type A/AB thread forming screws are specifically engineered for sheet metal applications where reliable fastening is critical. The 18-8 stainless steel composition provides exceptional corrosion resistance, making these tapping screws ideal for outdoor equipment, HVAC systems, and industrial machinery exposed to harsh conditions. The thread forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating strong, vibration-resistant connections. The combination of No. 1 square drive and pan head ensures positive driver engagement during high-torque installation, preventing stripping and ensuring consistent seating. With precise 0.138" thread diameter and 18 TPI configuration, these screws deliver optimal thread engagement in various sheet metal thicknesses up to the maximum drilling capacity of 0.025".
