So what exactly are fasteners?
Imagine a world devoid of vegetation and trees. You can’t, and you can’t fathom your surroundings without fasteners, either. Yes, they play an important and critical function in the field of engineering. When you hear the phrase “fasteners,” the image of screws, bolts, or nuts must immediately come to mind. Yes, however there are many more fasteners that we will learn about in this article.
A fastener is a piece of hardware that is used to connect or keep things together in a non-permanent manner. Yes, a joint can be non-permanent or permanent; in the former, the connected components can be readily detached without harming the joint, but in the latter, the joint is destroyed or loses strength.
How do you make permanent and nonpermanent joints?
Screws, bolts, nuts, washers, cotter joints, and other fasteners are commonly employed to construct non-permanent connections.
Welding, riveting, soldering, brazing, and other processes are used to create permanent connections.
What is the importance of fasteners?
Have you heard of the Boeing 747 plane? Yes, an American wide-body commercial jet airline known as ‘Jumbo jets,’ with about 30 lakh fasteners out of 60 lakh components. Fasteners are a common hardware component that may be found almost anywhere. Fasteners are used to attach things such as door hinges and household appliances, as well as automobiles, machineries, construction, infrastructure, and other goods that require assembly. What if a single fastener comes undone or fails? It will undoubtedly have an impact on the whole system or have negative repercussions. So the strength, durability, and rigidity of a structure are determined by the type of material used, the coating applied, and the dimensions of the structure, since proper fastener selection reduces stress concentration, which reduces fatigue. There are many different types of fasteners on the market, each with its own purpose. Fasteners might be ferrous, non-ferrous, or even plastic these days.
Types of Fasteners
- Bolts and Nuts
A bolt is a threaded fastener that must always be used in conjunction with a nut. External male thread is found on bolts, whereas internal male thread is found on nuts. A bolt has a head, a cylindrical body, and threads along the length of it. Bolts often have a flat head, which implies they don’t have a groove. It usually has a design on its perimeter that allows it to be driven by a wrench tool, and the same is true for the nut.
Fasteners that produce their own threads while attaching into the material are known as self-threading fasteners. They generally feature a head and a helical threaded shank. They come in a variety of head and recess or drive styles, including slotted, Pozidriv, Phillips, hex, Torx, Robertson, and so on.
These are thin plates having a hole in the centre and an outside diameter that is usually double that of the inner diameter, which are used to disperse weight over which they are fastened, such as on a screw or nut. In a variety of applications, washers can be employed as a spacer, locking device, wear pad, and so on. It can be made of metal, plastic, or rubber, depending on the situation.
It’s a permanent fastener with a head, shank, and tail that can’t be disassembled without causing damage to the joints. Riveting is the technique of applying force to two materials to connect them together. It can be done by hand or by machine. They are quite powerful in nature.
- Anchors Fasteners
These are commonly used to link structural and non-structural components to concrete or other materials in the building and masonry or stone industries. This is typically placed by drilling a bigger hole in the base material than the fastener diameter, and then inserting the anchor to a depth known as embedment depth.
These are strong threads that are generally cylindrical in shape and are used for a variety of purposes, including establishing a long-lasting connection between diverse materials or mending stripped threads. These are commonly used to transfer loads from a small screw diameter to a greater diameter of inserts.
- Snap Rings
These tiny metal rings, also known as retention rings, are broken at one end of the circle and have a grooved form at the other end. They are used to hold and grip components onto a shaft while settling into a machining groove. Shock absorbers and automobile engine components are frequent places to find them.
We make industrial application fasteners for a variety of applications, including:
Military – Fasteners intended to endure the stresses of high temperature, high wear, and corrosive conditions, such as those found in engines, motors, heat exchangers, and process equipment. We provide stainless steel, copper alloys, alloy steels, and nickel alloys in a variety of diameters, lengths, and thread combinations.
Turbines and power generations – Fasteners used in electrical equipment, turbines, motors, exhaust systems, pumping systems, and storage vessels. Turbine & Power Generation – Fasteners used in electrical equipment, turbines, motors, exhaust systems, pumping systems, and storage vessels. For their strength, high wear resistance, and anti-corrosive characteristics, nickel alloys, aluminum, steel alloys, and stainless steel are employed. Copper alloys are utilized for their electrical conductivity.
Chemical Refining — Fasteners made of stainless steel, tool steel, nickel alloys, and exotic metals that can withstand the high stress and corrosive conditions inherent in chemical processing. Heat exchangers, exhaust systems, tanks and vessels, and industrial equipment all require our fasteners.
