The fastener dilemma
Choosing fasteners is a critical part of any industrial application. Whether you are working with heavy machinery, production equipment or infrastructure, fasteners such as bolts, screws and nuts are essential for systems to function as they should. Choosing the wrong fasteners can have serious consequences, from machine failure to costly repairs and safety problems.
Incorrect fasteners can mean that equipment does not perform optimally, and in the worst case they can lead to catastrophic failures. In industrial operations it is therefore important to ask the right questions before you decide which fasteners to use.
The hidden costs of choosing the wrong fasteners
The wrong choice of fasteners can lead to a range of problems, including:
- Machine failure: If a fastener is not strong enough to withstand the load, it can fail, which can lead to serious machine breakdowns and production stoppages.
- Increased maintenance costs: The wrong fasteners can cause equipment to wear quickly, and you will have to replace parts and equipment more often, which increases maintenance costs.
- Safety risks: Fasteners have a number of “weaknesses”, including corrosion, breaking strength, tensile strength, vibration, and so on. For example, in applications where fasteners are exposed to high vibration, the wrong choice can cause working components to come apart, which can create dangerous working conditions.
How to choose the right fasteners: 6 questions to ask
To make sure you choose the right fasteners, you should ask yourself these six questions before you decide:
- What is the load it must withstand? Determine the fastener strength based on the load it must withstand. Match the strength class to the requirements of the application.
- What kind of environment will it be used in? Is the fastener exposed to extreme temperatures, moisture, chemicals or other stresses? Choose a material that withstands the environment in question.
- Which material is the best fit? Choose between stainless steel, carbon steel or other alloys depending on the working environment.
- What is the best thread choice? Choose between coarse or fine threads for your application, based on factors such as vibration or high load.
- Which strength class? The strength class (8.8, 10.9, 12.9, etc.) you choose must match the requirements of the application. Many people tend to think that at the very least they must not have bolts that are too weak, but remember that bolts that are too strong can also cause problems.
- Is corrosion protection necessary? Use fasteners with the right surface treatment, such as hot-dip galvanising or XYLAN.
Checklist for correct fastener selection
- Confirm that the fastener can withstand the required load.
- Choose a material that is suitable for the working environment.
- Make sure the threads are right for the application.
- Match the strength class to the loads the fastener must withstand.
- Choose fasteners with the right corrosion protection for the environment.
