The Baby 5/8" Pin for Bee 50-C and Hornet 200-C from HIVE LIGHTING is designed to mount these lights on grip gear with a 5/8" receiver, such as a Super Clamp. One end has male 1/4"-20 threads for the lights and the other has an anti-twist knurled 5/8" stud with a lip to prevent it from disengaging from the clamp or accessory.
