In the installation of many different objects in construction work, fasteners play crucial roles. It is also used in forming machinery to connect different parts. Fasteners aid in holding the parts in place while preventing excessive vibration and pressure that the machine produces while working. There are numerous types of this tool. The various types also have a relatively high level of variability.
In this article, the various types of industrial fasteners and their subtypes will be discussed.
What Is A Fastener?
A fastener is a mechanical tool that connects or affixes two surfaces or objects rigidly. Fasteners can be permanent as well as non-permanent.
- Non-permanent fasteners can be easily removed without causing damage to the joined materials.
- Permanent fasteners may require significant force to remove and may cause damage to the connected surfaces. They are intended to be a long-lasting form of secure connection.
Types Of Fasteners:
Below the broad categorization of Industrial Fasteners is listed.
- Bolts: Bolts are the most common type of fasteners that are hugely used. They are used to join two unthreaded parts.
- Nuts: A nut has an internal thread with a bolt to hold components together.
- Rivets: Rivets are permanent fasteners used to secure a variety of components.
- Screws: Screws are versatile fasteners with long-lasting holding power. These Industrial Fasteners have a structure similar to bolts. However, unlike bolts, they do not require anything to keep them in place.
- Washers: Washers are small, circular discs with an annulus shape. They also cooperate with nuts and bolts to perform critical fastening functions.
Sub-Types Of Fasteners:
1. Types of Bolts:
Bolts are the most commonly used Industrial Fasteners for connecting unthreaded parts. A bolt and a nut are used together to fasten any part of a machine.
- Bolts with Hex Heads
- Bolts with two ends
- Eye Bolts
- Carriage Bolts
- Socket Head Bolts
2. Types of Nuts:
A nut has an internal thread that allows it to work with a bolt of the same size. Using nuts users benefit from improved grip and increased torque. Nuts are available in various types and designs to accommodate various bolt shapes.
- Cap Nuts
- Castle Nuts
- Hex Nuts
- Weld Nuts
3. Types of Rivets:
Rivets are the most commonly used type of permanent fasteners. For the installation of rivets, threads are not necessary. They provide resistance to shearing forces and aid in the security of a variety of materials. As reverts are easy to inspect, they are popular in the aerospace sector.
- Multi-Grip Rivets
- POP Rivets
- Large Flange Rivets
- Tri-Fold Rivets
4. Types of Screw:
The structures of screws and bolts are pretty similar. At the tip, their male threads begin. The shape of their heads can also vary. These mechanical Industrial Fasteners come in a variety of designs. Each one serves a specific purpose.
- Sheet Metal Screws
- Self-Drilling Screws
- Hex Lag Screws
- Machine Screws
- Wood Screws
- Deck Screws
5. Types of Washers:
Washers are a type of fastener that is used in conjunction with nuts and bolts. They are typically installed beneath joints, nuts, and axle bearings. Washers perform a variety of functions, including friction reduction. They also aid in the elimination of leaks and the isolation of various components. Due to these features, a washer will help prevent the component from loosening due to vibration.
- Plain Washers
- Locking Washers
- Spring Washers
- Dock Washers
Select The Appropriate Fastener For Different Applications:
Industrial Fasteners are offered in a wide variety. However, it is crucial to select the appropriate one to meet the particular purpose. Additionally, it is essential for safety. But, selecting the proper fastener is crucial for more reasons than just increasing productivity. Let’s examine how you can always select the appropriate fastener.
· Understand the Application:
The requirements of the application will always determine the use. One must take into account whether the fastener will fit. Knowing how much torque a fastener can withstand depends on its design.
Before making a choice, one must consider the temperature at which the application will expose the fastener. Extreme temperature variations may cause fastened joints to expand and contract. This might result in a loose connection. Hence, the requirement for a fastener that can withstand the temperature is needed.
· Take into account the building materials:
Industrial Fasteners are made from a variety of materials. Steel made of carbon is the most common material. This is a result of its varied strength and workability characteristics. Additional materials consist of:
- Alloyed Steel
- Stainless Steel
Nowadays, numerous fastener types make it challenging to select the best one for your application. To ensure that the finished product meets the requirements, selecting the proper service provider and appropriate Industrial Fasteners is crucial.
