Thread Size Adapter - 5/8" Outer to 3/8" Inner For microphone stands and clips (also known as microphone holders) QTY - 1 Used For - There are two main industry standards for the screw threads on the top of microphone stands, 3 or 5 eighths of an inch. If your microphone came with a clip, it’s almost certain that its thread will be one size or the other, likewise, your microphone stand is also likely to be either 3/8- or 5/8-. If your stand is 3/8- and your clip is 5/8-, this adapter will allow you to use them together, filling the gap to ensure you have as snug a fit as possible, helping to deaden any unwanted vibrations. Construction - Manufactured from high quality alloy to prevent any deformation of the thread which could cause it to jam, the adapter also features a knurled skirt at the base to aid grip when attaching and removing it. Standards - ROHS Compliant
