While the entire bracket is lead-coated using a hot dip method, the thumbscrew is left natural copper. IF the thumbscrew were to be factory lead-coated, the additional thickness of elad would make it impossible to thread into the bracket.

Even so, you may still find that the un-coated thumbscrew is still difficult to thread in.

Sometimes the thumbscrew can be worked in and out slowly to “tap” the threads. If this doesn’t work, heating the threaded part of the bracket until the solder softens, then inserting the thumbscrew (you may have to preheat the thumbscrew as well) usually works.

Once the thumbscrew has been installed and the bracket is tight, flux the thumbscrew, then tin it with a soldering iron for a more or less perfect match.


At the lead-coating facility, the brackets are hot-dipped in molten lead, then placed on a cooling rack. While they are cooling workers manipulate the bracket’s gate to make sure that the lead doesn’t freeze the hinge.

Occasionally some still get through that have a frozen gate hinge.

If you have one of these, simply heat the hinge until the solder softens, then remove the heat and work the hinge back and forth until the solder cools, or if already on the building and ready to be closed, just move the bracket to the closed position before the solder solidifies.
