yep, 16 tpi, confirms it as 'unified national course',

I have those 4 long bolts you need. I was enjoying the same thing not to long ago. Is it for a Machine Mart heavy duty 4 arm device. Drop me a line if you need to borrow them.

Hi

I have recently mounted my 3.5 Rover engine on a clarke stand I bought a length of studding (also 3/8 unc) and some nuts and washers

I found this better than bolts as I could ensure that the maximum length thread could be inserted into the block to give as much support as poss'

quite cheap too less than £3.00 i seem to remember.

Just a suggestion

thanks for the offer, i have managed to find some bolts the right size and the block is now mounted on the stand.
plenty of work coming up over the holidays - christmas dinner in the garage for me as my wife suggested (was she bieng serious!!??:P )

have a good one -
