This invention generally relates to blind fasteners that are used in conjunction with mounting objects on hollow walls and ceilings.
This application is an improvement to U.S. Pat. No. 5,226,767. The background information for this improvement is exactly the same as it is for that patent.
It is the object of the present invention to provide a useful means for establishing an opening in a hollow wall or ceiling with a minimum of effort for the insertion of a blind fastener.
According to the present invention a double sided fastener is provided which is adapted to make an appropriately sized hole on one end for the insertion of the opposite fastener end of the invention.
The Self-Drilling invention is an improvement over U.S. Pat. No. 5,226,767. It changes the blunt end of that invention into a device that is capable of making a hole that enables the fastener to fit itself through.
