Eureka Expansion Bolt Project

An expansion bolt is a very handy and versatile fastener. It can be used for many applications and in the articles mentioned below it is used with a threaded rod and nut instead of the bolt that comes standard with the product.
If you have any new ideas for different applications, please send us your comments.
If you have problems with installation please send the details and we will reply with our solutions.

An expansion bolt is quite a difficult product to use. There are many aspects to take into consideration when using this fastener.
The two main things that can go wrong:

1) Not drilling the hole deep enough for the bolt causing it to strip the thread of the shell when tightening.

2) The next problem is that an expansion bolt has the ability to break or crack an object or surface when tightened. This happens because of the very big expansion of the shell as the bolt is tightened.

Here are links to two projects where expansion bolts are used:

1) A ceiling-mounted hanging shelf will provide you with ample storage space in your garage. These shelves should ideally be mounted into a roof made from concrete, although it can also be done through a normal ceiling by securing the threaded rod through strong wooden crossbeams placed inside the roof on the roof trusses.

2) Get to grips with expansion bolts and threaded rod
and hang a ceiling-mounted shelf. Read more

I will be glad to assist and listen to your ideas.
