Fastener

Fasteners
We mainly use a fastener for a non-permanent joint. Fastener is a joint that can be removed or dismantled without the destruction or damage of the joining components can be termed as a non-permanent joint. A welding joint or riveted joint can be termed as a permanent joint, which if required to be removed tends to damage or destruct both the joining components as well as the joint itself.

The basis of a fastener is basically a screw thread. – The male part is basically the screw with an external thread and the female part is a hole with an internal thread. The female part can also be a nut. Here are some ways by which a fastened joint can be created.

Based on the application area of the fastener, the head portion of the fastener is available in various shapes and sizes as shown below:

Here is a list of materials used for manufacturing of Fasteners:

1. Carbon Steel Fastener:

Ashtbhuj or Metal Handicraft Export is one of the leading manufacturer, exporter and supplier of high quality carbon steel fasteners in India. We also offer a complete range of carbon steel fasteners such as Bolts, Nuts, Washer, Screw, threaded rod and stainless screws etc. These carbon steel fasteners are widely used in various application industry. These carbon steel fasteners are available in different size, shapes, grades, specification and thickness as per the clients requirements.

Carbon steel is a popular material for fasteners due to its good tensile strength and ability to bear loads. It responds well to heat-treatments with minimal work hardening and brittleness. It is easy to machine and can meet the tight tolerances required for threading and fastener configurations. Carbon steel is also an economic metal. Carbon steel is categorized by the amount of carbon in the alloy, which impacts the properties of the steel. It has low tensile strength and can be hardened through carbonizing. It is the least expense of the carbon steel alloys. Medium carbon steel has 0.3-0.59% carbon, which provides the alloy with increased strength. It is easy to machine and is used for forged and automotive parts. High carbon steel and ultra-high carbon steel is very strong and is used for springs and high-strength products. These alloys can be tempered to very high hardness without brittleness, and are used for very high wear applications.

We are looked upon as one of the major Forged Carbon Steel Fastener Exporters from India. The use of optimum quality raw materials in the manufacturing of the Carbon Steel Fastener ensures high durability, tensile strength and resistivity to adverse conditions.

This is mostly used in aircraft application fasteners.

6. Aluminium Fastener:

One of the greatest challenges faced in the automotive industry is to reduce CO2 emissions. In order to this achieve objective, it’s crucial to produce vehicles that offers better fuel economy without compromising comfort, spaciousness and safety. And greater use of lightweight materials is a key part of the strategy to resolve this dilemma. Nedschroef therefore developed range of aluminum fasteners which enables the joining of lightweight components.

Light metals have much larger thermal expansion coefficients than steel. This leads to extensive thermal induced stresses, if a bolted joint with steel screws and magnesium and/or aluminum components is operating at elevated temperatures, for example in a gearbox housing. This can easily cause overstressing of the lightweight material, so plastic deformation in the stressed zone occurs and the clamping force is reduced significantly. Such relaxation problems in practical applications are showing self-loosening, fatigue failure, sealing defects, noise from components under vibrations or intensive local corrosion caused by gaps between head and support area. A much better result is achieved, if for the same joint a screw made of aluminium instead of steel is used. Because of the similarity between the thermal expansion coefficients of aluminium and magnesium there is almost no stress increasing and, therefore, almost no increase of surface pressure.
