Quality hardware cannot be beat and Horton Brasses delivers. I ordered from Horton Brasses for the first time a few weeks ago. I purchased their precision butt hinge in the large size and was very happy with the quality.
They are extruded solid brass and come in several different finishes. The Hinge also comes with the center hole elongated which assists in making fine adjustments if needed. The smaller version of this hinge does not offer the elongated hole.
Horton is also wise enough to ship two different screw types with the hinge. I received a set of brass screws in the finish I ordered and zinc coated screws for the initial mounting. Brass screws are soft and can break easily when driving them into a piloted hole for the first time. It is good practice to use a screw of the same size and harder metal for the initial fastening and that is what the zinc screws provided.
