Viking Burner Base Screw Part Pd020159

These are the real deal; they worked perfectly. The cost is pure extortion, ~$20/screw?? After some broader research, that seems to be the going price. I've no clue why it's so expensive. I did find them at b-o-l-t-d-e-p-o-t dot com (w/o dashes) for $0.10/screw, how these should be priced. The specs are M4-0.7 thread and 25mm long. It's a metric socket cap (surprising given it's a made in USA appliance). I hope this helps.
