ARP Thermostat Housing Bolts Hex Head Chrome Moly

ARP thermostat housing bolts with a hex head are made from chrome moly steel. They are also sold as thermostat housing bolt kits. They replace standard fasteners on the engine's thermostat housing, also called the water neck or coolant outlet. They hold the housing firmly in place and help keep the coolant seal reliable.

Key Features:

• Chrome moly construction: Chrome moly steel is strong and durable, so these bolts hold up better than basic hardware-store fasteners.
• Hex head design: A hex head fits standard sockets and wrenches, which makes installation and removal simple.
• Made for the job: They are built for the heat cycling and vibration of a working engine bay.
• Trusted brand: ARP is a well-known maker of high-performance fasteners for street, racing, marine, and powersports engines.

These bolts suit rebuilds, performance builds, and routine maintenance where you want a stronger, better-looking thermostat housing fastener. Choose the child item that matches your application.
