Find the correct Head Bolts for your car
Head bolts are sometimes referred to as long head bolts or cylinder head bolts. They're used to attach the cylinder head to the engine, but are otherwise pretty inert objects.
They don't tend to fail or wear out, but are very inexpensive to replace so it's always a good idea to change them if you're replacing the cylinder head or any other engine parts around it.
As head bolts are specifically sized for each car, you'll need to make sure you get the right ones. Just pop into your local Halfords store and find a member of staff - they'll be happy to help.
If you know what you need, you can even order the parts online and pick them up from your local Halfords store the following day.
