Use left hand hex nuts with any type of left hand threaded rod, bolt, or screw.

What is the screw pitch?

Pitch is the distance between screw grooves and is commonly used with inch sized products and specified as threads per inch. Lead is the linear travel the nut makes per one screw revolution and is how ball screws are typically specified. The pitch and lead are equal with single start screws.

What is the method of removing broken stud?
