These nut holders use 8-32 nuts to secure a pair of rail buttons to a body tube (BT).  They can also be used to add a mounting point for any other purpose in a rocket's construction.

The nut holders are meant to be epoxied in place on the body tube's inner wall (I use a rail  button and screw to keep the nut holder in place along with a bit of petroleum jelly on the internal threads, so the epoxy doesn't hamper rail button removal later).  Once installed, the buttons can be easly removed for painting or field replacement.
