Hi can someone do me a favour, i am thinking of having some stainless head bolts made, if anyone has a bolt handy can you measure the length under the head, diameter of shaft, depth of the threaded (M8 ?) hole, i think the 500 and 400 are the same. If succesfull i will offer them for sale on here to members.
