How to Choose the Type of Mechanical Fastening for Your Project?
Selecting the appropriate metal joining process is fundamental, as it affects the structural viability of the project. There are several aspects to consider when deciding on the best joining method. Welded joints and riveted joints are two popular methods of permanent metal joining. Depending on the project, both welding and riveting have their pros and cons.
Occasionally, especially in steel construction, we need to use both welded and bolted connections. It is very important for the responsible engineer to understand the implications of mixing rivets and bolts concerning connection strength, fatigue life, manufacturing costs, and the skill level required to perform each connection.
We should ask ourselves some questions before deciding on the type of mechanical fastening to use in our project:
- Will the fasteners be exposed to weather?
- What materials will make up the fastener?
- What is the thickness of the assembly?
- What are the strength, weight, and vibration load requirements?
- Do I have specialized labor and technical equipment?
Sometimes, the design engineer has the option to choose between rivets and bolts. Learn some of the differences between rivets and bolts.
Rivets or Bolts?
Rivets are metallic fasteners with a smooth cylindrical shaft and a head specially designed to join materials permanently by deforming one of the ends, while bolts are fasteners with a threaded shaft and a head, used with a nut to join materials.
Rivets offer a strong and permanent connection, while bolts have the advantage of being adjustable and removable.
Both bolts and rivets are essential components in the industry for joining and securing materials.
In recent years, many of our welding stud customers have been implementing the process with the insertion of screws and nuts using the insert or riveting system, often replacing welding studs due to product requirements.
When to Choose Each System?
Choose rivets when:
- You need a permanent and high-strength joint.
- You work with materials that do not allow welding.
- You seek fast installation in serial production.
- The aesthetics of the joint are secondary to functionality.
Choose welding studs when:
- You require maximum structural strength.
- The loads are extreme and dynamic.
- The joint must be permanent and monolithic.
- You work with thermally compatible materials.
Choose Bearfix insert systems when:
- You need the possibility of disassembly.
- You work with thin or heat-sensitive materials.
- Aesthetics and finish are important.
- You seek to reduce installation time and labor costs.
We have incorporated the BEARFIX range into our products, consisting of insertable and rivetable screws and nuts, thus becoming the only global supplier of weldable, rivetable, and insertable studs at the national level.
