It’s a common need to join parts using a threaded machine screw. You can use a conventional threadform tool if the thread pitch is greater than the material thickness. Things get more complex when the screw thread requires a material thickness greater then the pitch of the screw. In these situations, options such as self-clinching fasteners or self-tapping screws are viable, but add secondary operations and/or special hardware. These “extras” add cost, which can reduce competitiveness and profits.  Mate can solve this problem with the Hybrid Threadform™ forming tool.

The Hybrid Threadform tool is designed to thin the material in the center of the form and create the threadform helix in just one operation, allowing you to join different material thicknesses. At the heart of the tool is an upper and lower insert that is machined with a profile that precisely matches the thread helix of the screw thread. The geometry of this part is modeled by a Mate Applications Specialist using our advanced CAD software, creating a three-dimensional solid model for your specific requirements.

 

 

 

 

Hybrid Threadform provides the following benefits:

• Eliminates secondary operations
• Eliminates tapping operations
• Reduces debris in the machine caused by tapping
• Reduces component cost by eliminating any special fasteners

For added benefit, you can combine Hybrid Threadform with other Mate forming applications such as EasyBend™ for forming corners or EasySnap™ to break apart pieces from the sheet.
