Since nobody else has chimed in yet, I'll tell you what I know.

Torque spec's for bolts depend on bolt material/grade, diameter & thread pitch. The dimension across the flats of the nut doesn't have an effect.

You can look up general purpose fastener torques on charts like this one - http://geotecsolar.com/wheel-nut-to...t-fabulous-model-t-ford-forum-lug-nuts-torque

In specific applications, those torques may be too high because of limitations imposed by the materials that are being bolted together.

I do not have specific information for your particular application.

Thanks Jim. This is not a typical application as there is fiberglass between the plate and the washer/nut. I will look at the table but probably not a good idea to follow the torque developed for steel.

Thank you
