Extruded Threaded Holes Sheet Metal

You can imagine the shape as being a body to the punch of any shape and from this protrudes the punch pin of the diameter you want.

Extruded threaded holes sheet metal.

For the tapped screw hole this is typically made using a male punch that creates the hole and extrudes the metal. Extrude tite screws were designed to resolve the fastening problems of stripping and spin out in thin sheet metal found when using standard round bodied sheet metal screws. The diameter of the pre punched hole ultimately determines the height of the extrusion. Therefore the minimum distance between the extruded hole to edge if maintained.

Both holes and regular extrusions are possible in sheet metal as well as thread features. Center of extruded holes a 5 hole dia 2t extruded hole and bend edge c 3t r d 2. Extruded hole to part edge b 3t d 2. Mark as new.

A pre punched hole is required as a one hit pierce and extrude gives poor hole quality and has limited adjustment on the machine. Tap fix screws for extruded holes in light gauge steel this article provides tap fix hole size recommendations for metals using light gauge punched extruded materials. Extruded holes for metal sheets there are so many more complex features in the metal sheet environment. Increased torque performance in thin sheet metal applications.
