We bought an old school building and we're having challenges with some of the windows. We need to order about a dozen of the following: A replacement for a 1/2' thick tilt lock and also the pin/screw to connect it to the spring (probably a 1/4' diameter). Marking on the plastic piece is a patent number 4610108. Can you tell me the easiest and quickest way to order those? Can we get them from you? Product numbers? Prices? Thanks!!

Hello! We offer a wide variety of such parts, and there's a good chance we have what you need. I'm afraid I cannot identify what you have based on the patent number, though. We will need to see a couple pictures of the hardware in question, including detailed dimensions.
