Wing Strut Bolts - Washers?
We are just about to fit new wing strut bolts to an Auster J1N.
The book (not updated since 50s/60s) clearly shows no washers under the bolt heads.
The aircraft arrived with washers under the bolt heads!
Does anyone have a best practice please?
Thanks,
Simon

I have found the same anomaly during my Argus rebuild - are the bolts the correct length? - I found some that were one size too long.

Re: Wing Strut Bolts - Washers?
I would put the washers under the bolt heads in order to spread the load in the area, act as a bearing surface- if the hex heads “dig in” without them, they can tear the undersurface.

Thank-you Bill, those were my thoughts too.
Yes thanks Frank, they look correct length.

The strut tangs are a loose lateral fit in the fuselage fitting so the bolt should only be nipped up otherwise the fitting will be distorted. I think washer as necessary to achieve this with the plain shank taking all the load.
