Extruded Tapped Hole Sheet Metal

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 tapped hole sheet metal.

The following illustration shows the extruded hole geometry. Avoid large sheet metal parts with small bent flanges. Tapped holes may need to be re tapped after plating to ensure accuracy. Creating an extruded hole using a punching process requires extreme pressure force.

They are used in thin materials. Extrusions our commonly used to accept sheet metal screws or permit tapping into a deeper distance than just the material thickness. Extruded tapped hole u nuts push the workpiece material downward to create a tapped hole. Design for manufacturability sheet metal guidelines bends for the ease of manufacturing multiple bends on the same plane should occur in the same direction.

Performance in extruded holes is slightly higher than in drilled holes. The minimum distance from an extruded hole to a bend is three times the material thickness plus the bend radius. Therefore the minimum distance between the extruded hole to edge if maintained. The tooling produces a full range of threaded holes in.

Prepunched or extruded holes on the sheet are threaded through a coordinated rotation of the turret press autoindex station and ram stroke. Extruded hole to part edge b 3t d 2. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm. Avoid large sheet metal parts with small bent flanges.
