Fasteners and Fixings Question: Why Did Those Bolts Come Loose?

There is nothing more aggravating for a home improvement expert than finding that bolts have come loose. This problem can occur for a couple of reasons. If you are having trouble keeping your fasteners and fixings from coming loose, you may find this information helpful.

Fasteners and Fixings Question: What Cause Bolts to Come Loose?

The majority of the time, bolts come loose because a reduction in friction. When this friction works properly to your advantage, it keeps the bolts in place and resists any movement that may occur. However, the threads on a bolt tend to slope downward, which means that any type of movement that occurs will affect the amount of friction resisting the movement of the bolt.

Each time your bolt is moved, you can expect the nut to move slightly along the thread of the bolt. At first, this movement will not be noticeable, but over time those micro movements will result in a loose bolt.

Another reason for bolts coming loose is the method of tightening that is used. If not properly tightened down, the bolts are more likely to be affected by movement and become loose. This may also occur when you place the bolt, move on to another part of the project, and forget to come back and tighten the bolt down.

Fasteners and Fixings Workshop Tip: How to Prevent Bolt Loosening

There are a few ways that you can reduce the amount of loose bolts you have to deal with.

Thread Glues- Several glues available for sale today will work well at reducing the amount of loosening that occurs with your bolts. They are able to fill in the spaces between threads, preventing any type of movement from occurring without damaging the nut or the bolt.

Mechanical Locking-In some instance, you may need the assistance of a mechanical locking system or wire. Used in many instances where safety is a necessity, these locking wires and systems have been proven to prevent bolt slipping.

Serrations-There are some fasteners and fixings that have been designed specifically for the purpose of preventing loose bolts. These usually have serrations that ‘dig in’ to stop slipping.┬ázip ties

Double Nuts-Using two different nuts may be an effective way of reducing the amount of loose bolts you have to deal with.
Washers, even ones that claim to be anti-loosening, offer little to no protection from tension and friction reduction. While some may work effectively for small problems, they will crumble under the pressure of inadequate tightening or friction reduction. If you need to use an anti-loosening system, consider other choices before you decide to use a standard spring washer for your home project.

Although these preventative measures may help, you should always attempt to use correct tightening methods before you choose to use glues, nuts, serrations, or a locking system. Accurately tightening your bolts will help prevent slipping and will protect your fasteners and fixings from other problems like bolt wear, bolt fatigue, and leaks.
