Abstract
Disclosed is a bolt assembly which includes two spacers having cooling channels defined therein which communicate with a central bore, and a bolt which extends through the bore of each spacer. The diameter of the shaft of the bolt is significantly less than either of the spacer bore diameters, allowing coolant entering the cooling channels of one spacer to circulate through the spacer bores and out the cooling channels of the other spacer, thereby cooling the bolt.
