Barrel Nut (862) with center 1/4"-20 thread
Includes 1pcs Nut
Manufacturer Part Number: Nut-862
The barrel nut seems ordinary but its function is extraordinary, according to my experience. It could attach magic arm with 1/4¡± screw on the one end and attach cold shoe mount with 1/4¡± screw on the other end. That¡¯s great!
