I am a new owner of a 2001 2100SC which we are in the process of sorting out in time for the summer season. With many jobs to finish, one I am stuck on is the refitting of the front seats. The bolts were extremely rusty and need replacing but I am told they are not metric so I assume they are UNC or UNF? Does anybody know the size so I can order some please? I am referring to the four bolts that hold the seats to the runners. The type of seat we have are the two back to backs that fold flat for sun loungers. Sadly in deepest darkest Devon nobody stocks anything other than metric! Thank for your help in advance.
Wasn't looking to replace the nuts as they are captive in the runners. If I have to drill them out and replace them I will but I had hoped it could pick up some replacements. Nobody here can match the thread so I can't even order any off Ebay.
By luck I now know the size. They are 1/4 UNC x 3/4. Just to make sure, these are the 8 bolts that hold the seats to their runners. My boat has the standard back to back seats. Hope this helps? I can find the link for where I ordered them from if you need it. £1.80 worth of bolts and £4.00 postage but worth it to get the seats back in!
