Extruded Threaded Holes Sheet 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.

Extruded threaded holes sheet metal.

The diameter of the pre punched hole ultimately determines the height of the extrusion. Increased torque performance in thin sheet metal applications. The following illustration shows the extruded hole geometry. Extruded hole to part edge b 3t d 2.

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. 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. Can we have an extruded hole tool for metal sheets please. Extruded holes very close to the part edge can lead to sheet metal deformation or tearing.

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. For the tapped screw hole this is typically made using a male punch that creates the hole and extrudes the metal. Therefore the minimum distance between the extruded hole to edge if maintained.
