smaller glands of alternative threads forms.

Following the basic rules in line with good engineering practices no more than one Reducer should be used at any one time.

Standard item has a hexagonal head where space is a critical factor Reducers with a circular head can be offered having a diameter equal to the across flats dimension of the hexagonal head.
