    I am trying to determine the bolt size on something I am modifying as I need to buy additional nuts but other than it being I think M6 and 1.5mm pitch I am struggling. The only thing I know for sure when looking through my box of spares for a match is that it is the same as the lengths of threaded bar that you get in replacement letterboxes.

    Anyone know the exact gauge of this bar? If I determine that it should make searching online a lot easier.

    Traditionally, the thread was BSW.....British Standard Whitworth.

    Go to a local nut and bolt shop - they should tell you what you have and be able to sell you the nuts to match :cautious:
