APE studs are made from the highest grades of heat treated chrome moly , then centerless ground and have rolled threads only after the heat treat process to provide for maximum strength.

APE originated the heavy duty studs for performance motorcycles and today is recognized as the industry's leading manufacturer. APE studs are called on in most all of the top engine building shops. 

The Hayabusa engine uses head bolts instead of the preferred stud arrangement. When engines are subjected to bigger bores, higher compression ratios, nitrous oxide, turbo, etc..... the stock head bolts ARE NOT up to the task. Blown head gaskets are the result....................

The APE Hayabusa studs are made from ultra high strength, heat treated, premium 8740 steel and feature rolled threads for maximum strength. Safely torque these studs to a whopping 60 lbs for maximum holding power!! APE head nuts are machined from billet stock and heat treated to prevent threads from stretching. This set up is a must for all serious go fast motors. Extra thread on the nut end allows them to also be used with no plate when using APE CHN10125-10 cylinder head nuts.

Please note: The cylinder head can not be removed with engine bolted in place when using these APE studs
