CAT C12, C15, C16, and 3406E Head Bolt Socket:

CAT C-12, C-15, C-16, and 3406E Head Bolt Socket

Used to remove the head bolts on CAT C12, C15, C16 and 3406Es where the front two and back two head bolts are positioned under the valve covers. Clearance on certain head bolts requires a thin walled socket that needs to be a certain length. Also used on Detroit Diesel main bearing cap bolts and 19 mm head bolts on Mercedes-Benz MBE904/MBE906 EGR engines (2007 and later). Heat treated to optimize impact service life with a lower hardness than hand sockets and are able to withstand repeated cycling loads of impact wrenches.
