Rocky Mountain Hardware Door Striker Latch Plate These screws came from a company that had the contract to replace all the door hardware in the Idaho State Capitol. Rocky Mountain Hardware had the contract to make the molds and manufacture new hardware based off the old hardware and a Boise architectural supply company had the contract to do the work replacing the old hardware. The supply company had surplus made and when they went out of business these screws were sitting on their shelf. As of 06/14/2023 I have other door parts from the Idaho State Capitol surplus that you can see on eBay.
