Zhuocheng Fronthead Bolt Nut

What happens if head bolts or studs aren't tight enough? There's a lot of cylinder pressure in your engine while it's running and if the heads aren't sealed to the block this pressure will find a way out, typically into your coolant channels. Conversely coolant can also enter your combustion chamber.

Screws work much in the same way as a bolt, with one key difference. Instead of using a nut, they utilise an internally threaded hole. Screws come in various shapes and sizes, such as machine screws, self-tapping screws and grub screws.

A bolt is meant to be used with a nut, and it is tightened by torquing the nut. A screw is designed to be used in either a preformed or threaded hole, or it is able of forming its own threaded hole. A screw is designed to be tightened by torquing the head.
