Detailed Description

HBK909 is a precision-engineered cylinder head bolt set used to secure the cylinder head to the engine block. In applications such as Toyota Camry, Toyota Tacoma, and Lexus ES300 repairs, proper head bolt performance is critical to maintaining compression, protecting the head gasket, and supporting reliable engine operation after teardown. This set is manufactured from durable, heat-treated steel for strength and fatigue resistance in demanding engine environments.

This part cross-references Beck/Arnley 016-1012 for the same application.
