One problem is the narrow part of the inside of the lamp shade near the narrow neck space makes it difficult to reach with one's fingers. Holding a nut can be difficult in this narrow space, especially when an installer is reaching upward to remove or install shades onto light socket that are above their heads.
The use of a spanner wrench or spanner tool has been used for tightening these hard to reach nuts. However, the spanner wrench adds an additional cost and expense to the installation.
Other types of fastening techniques have uses thumb screws that pass through the outer surfaces 2 of the base 1, which are then tightened to abut against surface portions on the outside of the shade neck 14. However, these small screws are also hard to manipulate with one's fingers. Additionally, the screws can easily become dropped and lost during installation. Still furthermore, with candelabras type lights mounted to ceiling fans, vibrations have caused these small screws to become loose and fall out. A falling glass shade can be easily broken and also be a danger to persons underneath the light fixture.
Thus, the need exists for solutions to the above problems with the prior art.
