Self-through hole stand-offs are cylindrical spacers that provide a strong and permanent threaded or unthreaded standoff in thin sheets of metal. They are installed by pressing them into a pre-punched hole, causing the sheet metal to cold flow into a specially designed undercut groove, creating a robust mechanical attachment. These stand-offs are used to space or stack components, allowing clearance and alignment in assemblies. Their secure fit and ease of installation make them an ideal choice for various applications requiring precision and durability.
