Vented Screws to Dispel Contaminents

Q: I have an application where I need contaminants to vent. I want to limit the amount of atmosphere that is vented – can I specify the diameter of the drill hole in a vented screw?
A: Yes, depending on the diameter we can produce vented screws that are per your custom specifications. Please provide a print of what you need so that our engineers can review it.
