I need a part that will act as a spacer but it needs to be threaded on the inside to take a 1/4" bolt on both ends. It needs to be about 1 5/8 in length (no need to be exact).
I searched in Lowes and HD and couldn't find a match. The have threaded rods in varying lengths and sizes but they don't have the "female" version of this. I tried to search online but cannot find it since I don't know what it's call.
Application - I need to attach a custom mail box to a metal door (hollow in middle about 1 5/8 space). There are 1/4" bolts from inside and outside (I don't want to use nuts on one side), I found some hexagonal shaped nut couplers but those are too big diameter wise, I am trying to find some that will not require me to drill a hole bigger than the head of the bolts themselves. I remember seeing these parts used in door locks, ceiling fan rod extensions etc...
Thanks,
MC
