Adjustable bolt hinges are designed with a unique feature that allows for gate adjustments to be made after the gate has been installed. This adjustability is achieved through a bolt that can be tightened or loosened to change the position of the gate that the hinge is attached to. This feature is useful in situations where the gate may sag over time due to wear and tear or changes in the surrounding structure. The bolts below offer weld on applications as well as a hinge with a screw on bracket. These hinges can carry weight from 165 lbs. per pair up to 485 lbs. per pair.
