[Duluxdoggy]

hi, i want to do a small mod to my chair, gonna lower the arms a bit, to do this im going to un bolt the arms from the underside of the chair, place a block of mdf, and use longer bolts, so i ordered some 80mm m6 bolts, but the thread pitch is different, im not an engineer and dont know what to order next, here is a pic of em side by side, the one on the right is the thread i need, the one on the left is m6x1.0.

Or Auto Part store. Most of them will have a thread template. You thread your fastener into the template and it confirms your thread type. They also sell spacers instead of using mdf/plywood. Can be of more convenience than walking through a big box hardware store.

sorry, i failed to check for updates, didnt notice your post, i went to a local hardware store (b&q) but they only stock metric, and i cant go off the had size as they are hex key bolts, i will take a shot and your estimate and order some qtr inch.
