Helmet mounted earmuffs

[bhh]

Totally random question but I've lost the screws that mount my earmuffs to my forestry helmet. Pretty sure they are a standard size, anybody know what it is?

Type and name of helmet would help.
Go to the manufacturers site?
Logging supply jobber.
Take the helmet to the hardware store. Around here they have a static display of screws that can be used for finding the correct size.

Thanks for the reply. I believe it is a Labonville but I think all those helmet mounted muffs use a standardized mounting system. Problem is I came off and left it at the farm which is a few hours away. I'm heading up this weekend to do a lot of work there and was hoping I could pick up a screw before I head up. Wishful thinking I suspect but I figured it was worth it to ask.
