The zinc chromate bolt-on pivot hinge 4" is an ideal heavy-duty option for gates, doors, and other projects. Made of steel, these hinges can hold up to 300 pounds per pair, allowing you to mount light to medium weight gates and doors. From residential to commercial use, installing these pivot hinges is a breeze.

If you don't want a weld-on hinge, the bolt-on pivot hinge, 4", zinc chromate option is what you need. Although made of steel, these pivot hinges have a zinc chromate finish. The height of the attachment plate is 4" with a width of 1 - 7/16". They allow for a 180-degree range of motion, 90 degrees in each direction. A useful benefit of this steel pivot hinge is the adjustability of the gap between the gate post and frame after installation. With half an inch to work with, the gap range will be between 2 - 7/8" and 3 - 3/8". This will help prevent the need to re-install the hinge or buy a different one due to improper fit. The zinc chromate bolt-on pivot hinge 4" features a sealed roller bearing, so no greasing is required. These install with four 1/2" diameter lag screws and hex bolts. Using this size of hardware will ensure the 300 lb. weight rating. The mounting hardware is not included and must be purchased from another source. Please note that these pivot hinges are sold individually, not as a pair.

I have a hinge that I am trying to replace but I need help identifying it. Can you help?

Yes! Please click here to visit our Hinge Finder page.

Some of your hinges are sold by the each and some sell by the pair. What is the difference?

When the unit of measure says “pair” that means two hinges. Usually you need one pair of hinges per door. When the unit of measure says “each” that means one hinge. You would usually order 2 “each” hinges per door.

I want to replace my hinges. How do I make sure the screw holes on the new hinge match the screw holes on the old hinge so I do not have to redrill the holes?

Unfortunately, hinge manufacturers have never standardized the location of their screw hole patterns. Every manufacturer puts their screw holes in a slightly different place. This means that when you replace hinges you will almost certainly have to do some filling and redrilling. The exception to this is Architectural door hinges which are built to a standardized template for each size hinge.
