    Sponson Bolts... 18-8, 304, 316?

    Hi there!

    I'm in the process of removing the 6 broken sponson bolts that will likely break the remaining 4 lol. I've got 3 of the problem children out so far without too much trouble. Center punch, start drilling with a very small bit and then go to the left hand bit until it backs out just enough to grab with my needle nose.

    I'm at a stand still until I move this with it's partner on the double trailer enough to get in there and operate.

    So. I've determined the bolts are 1/4-20x1".

    Any opinions on which grade to purchase?

    Thanks for looking!

    Jimmy

    Well, loading up to leave for The Keys in 6 days, so I just ordered 18-8, as that seems to be the most common. I'll try to remember to report back if these fail, in case someone down the line is trying to find a readable way to replace these bolts without spending $19/ bolt lol
