Mate Precision Tooling, Anoka, Minn., has released a video at www.mate.com/en/fabrication-solutions/innovative-solutions/hybrid-thread/ featuring its Hybrid Threadform forming tool. The tool fastens two pieces of sheet metal together without tapping or secondary operations. The 4-min. video shows how one user saved 150 percent over traditional welding methods, the company reports.
The tool has an upper and lower insert machined with a profile that matches the thread helix of the screw head. Designed for use when the material thickness is greater than the screw pitch, the tool thins the material in the center of the form, creating a thread form helix so that the material fits between the pitch of the screw head in just one direction. It operates at 200 SPM.
