ChromLives Tripod Nut - Barrel Nut Connection with 1/4''-20 Thread Hole for Articulating Magic Arms, Tripod Rigs - Replacement Part Review

I either use them to change the bottom of tripod mounts or in the case of my DJI OSMO Pocket I also use male to male adapters as spacers. It keeps accessories away from the camera stabilizer head.

My monopod didn't have a regular camera thread. These adapters allowed me to combine the performance of a monopod with the stability of a tripod by adding tri-folding legs to my monopod.

I used one of these to convert my old Logitech C910 webcam which (unlike the newer C920 and C922) didn't have a tripod mount thread so it could be mounted on a tripod (or as pictured was compatible with the tripod mount). in the attached figure). A few drops of Gorilla Glue and you're done.
