I am trying to determine the name of a piece of specialty hardware. It consist of a screw at one end and a bolt at the other. You screw the hardware into a piece of wood and then you leave the bolt extended to attach something to the wood using a nut. I need to find some, but I do not know what is the correct name.
Thanks for any help.
Its called a hanger bolt
I believe they are called water closet bolts used for mounting toilet stools to the floor
These are often referred to as hanger bolts.
Commonly used with top/leg mounting plates
And corner leg / apron brackets
Bonus round - the fastener that has the coarse threads on both ends is known as a dowel screw
