Thread conversions from 1/4″-20 to 3/8″-16 are quite common. Thread dimensions are listed with two numbers. For instance 1/4″-20 means that the diameter is 1/4″ and there are 20 threads per inch. This is the most common size for the tripod mounting socket on a DSLR camera. 3/8″-16 means that the thread diameter is 3/8″ and there are 16 threads per inch. This is the most common size for tripod heads. This little stud will give you the ability to join two items together with different thread diameters.
