Professional Applications & Engineering Value

This 316 stainless steel Phillips truss head tapping screw delivers exceptional value in sheet metal fabrication and industrial assembly applications. The thread forming technology eliminates the need for pre-tapped holes, creating strong, permanent threads that resist vibration loosening and provide superior pull-out strength. The wide truss head design offers an enlarged bearing surface that distributes clamping force effectively, preventing damage to thin sheet materials while maintaining secure fastening. With its fully threaded No. 12 diameter and precise 11 threads per inch configuration, this fastener ensures maximum engagement in metal substrates up to 0.025" thickness. The A/AB tapping screw type specification guarantees consistent performance across various sheet metal grades, making it ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where corrosion resistance and reliable fastening are critical.
