Do you have the broken one to take with to hardware store?

If you take a photo with a penny next to it i can get you a thread pitch using Photoshop.

A penny is exactly .7500 inches makes a perfect reference

Place broken piece next to penny take from a distance with zoom to reduce parallax. Been using this method over a decade to find out things like exact size of a DC power plug to the 1/10 mm
