Nut & bolt fastener upgrades: wing nuts, thumb screws, etc

These are fastener adapters. Use them for prototyping before buying specialized fasteners or use them permanently!

The models are sized for a SAE ¼ inch - 20 threads per inch nut and bolt (¼-20). This leads to a 7/16 inch regular hexagon. Scale up or down to fit any nut/bolt metric or standard. 

Feel free to message me with requests for additional fastener designs.
