The Manfrotto 208HEX 3/8″ Head Mounting Plate fits into 5/8″ HEX sockets such as the Super Clamp, providing a mounting plate with a 3/8″ screw. Comes with locking screws.
Its main feature is the hexagonal pin, which, compared to the 208’s round one, gives more grip when used to hold heavy cameras mounted on photo or video heads in combination with accessories like the super clamp 035.
