Frequently Asked Questions (FAQs)
1. Why use dome head bolts?
Dome head bolts are used to prevent the bolt from being pulled through wooden construction and to prevent removal or loosening from one side. However, they cannot be installed using screwdriver bits or a socket and spanner.
2. What type of bolts are used on cylinder heads?
Head bolts are used to fasten the cylinder head to the engine block in internal combustion engines. They can also be used to attach other parts of the block, such as camshafts, timing chain covers, and oil pans.
3. How much torque do you need for engine head bolts?
For engine head bolts, it is recommended to tighten each bolt to 12-15 foot pounds of torque.
4. What are the benefits of knurling?
Knurling provides a better grip on the knurled object, enhancing the ability to hold and manipulate it. This is especially useful when dealing with smooth metal surfaces. The knurled pattern can vary, including straight ridges or a helix pattern.
5. Why do people upgrade head studs?
People upgrade to head studs because they provide a stronger clamping force compared to head bolts. This increased clamping force helps to properly seal the cylinder head, head gasket, and engine block together, allowing the engine to handle more power effectively.
6. Should you grease cylinder head bolts?
In most cases, it is recommended to lubricate the threads and underside of the head of standard automotive head bolts with motor oil before installing them.

Insufficiently torqued head bolts or studs can result in improper sealing between the cylinder head and engine block. This can lead to cylinder pressure escaping into coolant channels or coolant entering the combustion chamber.
8. Should I torque the nut or bolt head?
Whether to torque the nut or bolt head depends on the application and condition of the materials being fastened. In many cases, torque can be applied to either the nut or bolt head without compromising the connection's integrity.
