Techniques to hold threaded work for machining. This can include bolts, threaded rod, or many other items such as tool parts or parts you have made. Threads can be easily damaged by the jaws of a chuck. There are various methods of protecting the threads from damage such as wrapping then in sheet metal such as aluminum, making a split bushing, split nut, or collets. Here I discuss those methods and show a thread holding collet that I made for my projects. Thank you for watching.
