I have a 53 year old metal Butler building . I am putting some skylights on the roof and the original bolts in the building are 5/16 X 1 with insulated washers on them. They are self tapping bolts.
I have a few but need probably 100 to finish the job. I completed one yesterday and it worked out perfect. I could not believe how bright the shop is in the area it was installed.
I have looked everywhere for a bolt this size but all I find are #12 screws. The purlin all have 5/16 holes already in them and this is what I would like to put back. Any suggestions appreciated on where I could find some bolts like this. Tom
