🔩 The difference between iron, steel, brass and galvanized bolts and nuts

In the world of industry and construction, choosing the type of bolts and nuts is as important as design and execution. Each material has its own technical characteristics and specific application, and its correct selection guarantees the durability and safety of the structure to a large extent. In the following, we will examine the difference between the four main types of bolts and nuts:



⚙️ Iron bolt and nut

Features:





Made of plain carbon steel



High resistance to pressure and impact



Reasonable and economical price



No anti-rust properties (it rusts in moisture)

Applications:





Construction and metal structures in dry space



Automobile and heavy machinery industry



Projects that require high mechanical resistance

Tip: To prevent rusting in a humid environment, the screws can be painted or coated with rustproofing.

Summing up

Choosing the type of bolts and nuts does not depend only on appearance or price; Rather, working conditions, ambient humidity and pressure should be taken into account.

If your project is in a humid environment, steel is more suitable; They are the best options for dry, iron or galvanized metal structures; And for decorative or electrical work, brass is an ideal choice.

As one of the specialized centers in the supply and production of industrial parts, Roltrans store has gained a prestigious position in Iran's bolt and nut market with extensive experience in supplying all kinds of high-quality and resistant washers. One of the important parts of this group's activity is the provision of plate washers, multi-pin, double multi-pin and wave spring washers, which play a vital role in increasing the safety, durability and performance of industrial connections.

🔩 Plate washer
Plate washers are one of the most widely used types of washers in various industries. This type of washer, with a conical or plate-shaped design, is able to apply a uniform pressure force to the surface under the screw or nut.

The most important feature of the plate washer is to prevent loosening of connections due to vibrations or temperature changes. Rolltrans manufactures and supplies plate washers made of high-strength steel with anti-rust coatings, which are suitable for use in machine-building industries, metal structures, oil and gas industries, and power transmission systems.

⚙️ Hazarkhari washer
Hajarkhari washer is considered as a type of locking washers. The special design of this washer includes numerous prongs or spines on its surface, which are stuck to the surface of the workpiece when the bolt and nut are tightened and prevent rotation or loosening.

Roltrans produces its thousand-pin washers in different sizes and thicknesses to be used for all kinds of industrial bolts and nuts. This type of gasket is suitable for high vibration environments or equipment that requires a secure and permanent connection, such as transportation equipment, heavy machinery and agricultural implements.

🔩 double thousand-thorn washer
For applications that require greater stabilization and locking power, the double milled washer is the ideal choice. This version of Hajarkhari washer consists of two layers of washers with opposite spikes. This structure causes both directions of rotation of the screw or nut to be locked, and the possibility of its opening in the conditions of vibration or severe mechanical pressure is minimized.

Rolltrans double thorn washers are produced with high precision and from fatigue and corrosion resistant steel and are very durable in harsh industrial environments.

🌀 Wave spring washer
The wavy spring washer has a special design with a wavy surface that can act like a spring. This washer is used to compensate for expansion, contraction or pressure changes in mechanical joints. Its main role is to provide uniform preload force and prevent loosening of connections over time.

Rolltrans wave spring washers are produced in different sizes and materials from stainless steel, spring steel and special alloys and are very suitable for use in the automotive industry, precision equipment, electrical industry and mechanical tools.
