This new and improved M8-1.0 X 13mm long X 17.5 flange screw/bolt with 10.9 hardness.The new screw/bolts will make it easier to tighten and remove with a 12mm hex head. I custom ordered these screw/bolts so that they will fit under the right side clutch cover. Contact me at 24hrfun@gmail.com or ebay.com or amazon.com
