A cylindrical fastener with a low-profile,hexagon shaped head. The end opposite the head is internally threaded. It is considered a "blind" fastener because the threaded section does not extend through the entire length of the standoff. Immediately below the head is as light indentation that extends completely around the item's circumference. This indentation, or groove, provides the clinching action when the part is pressed thru a properly sized hole in sheet metal.
The standoff becomes permanently set when squeezed into place into a proper size drilled or punched hole. After it is pressed into place, the standoff forms a flush surface with the sheet metal.
