Guide/Pivot Pin for Window Sash

There are no markings, names, or part numbers on the existing hardware or the window.
The pin has the following dimensions:

Pin diameter: 4 mm
Pin length (from washer): 13 mm
Washer diameter: 11 mm
Washer thickness: 1 mm

The “washer” appears to be an integral (molded) part of the pin rather than a separate component.
On the opposite side of the washer are wood screw threads. The remainder of the screw has broken off and is still embedded in the window sash.
Although the pin has an aluminum-like appearance, it is magnetic and therefore appears to be made of steel.
Please let me know if any additional information or measurements would be helpful. I’ve also included a photo for reference.
Thank you for any assistance you can provide.

Hi Tom,

This part serves as the pivot pin for a tilt-in window sash. It screws into the lower side of the sash on each side and allows the window to tilt inward for cleaning.

The broken portion is the threaded section (similar to a wood screw) that fastens the pin into the sash up to the integral washer.

Unfortunately, removing an intact pin would be difficult without risking damage, since it is screwed directly into the sash. However, I can provide photos of the part in place, along with the installation location, if that would help.

Please let me know if there are any specific views or additional measurements that would assist with identification.

Thanks again for your assistance.
