One of the most widely used types of connections in various industries are bolts and nuts.

In fact, the most important components of a machine or system are these connectors and fasteners.

Below you will learn more about this product and the production of the large “Mashhad Crepe” collection.

Connections that are commonly used in various industries such as: steel, mining, oil, gas and petrochemicals, transportation and road construction, metal structures, various equipment and machinery, and automotive manufacturing.

The word (BOLT) is a Latin word that refers to all threaded fasteners such as: double-headed screws, U-bolts, stud bolts, and machine screws.

A “U-bolt” is a type of double-ended threaded bolt that is shaped like an English U.

This connector or page bends in the middle under certain heat and becomes a U.

The main function and reason for producing and manufacturing this type of crimp and fittings is to restrain or fix pipes (water – gas – oil – petrochemical) to prevent vibrations or movement.

در خوردروسازی نیز این وظایف خطیر به عهده پبچ ها و کرپی ها میباشد.

Today, even crepe Ubolts can be used to connect ropes – tow ropes (tow rope clips), guardrail harnesses and tubular structures, or in the automotive industry.

Among the types of bolts, one of the most widely used is called Ubolt.

One of the applications of crepe is in the connection of automotive parts. For example, crepe is used to connect axles to the suspension and spring systems of a vehicle.

This equipment plays a very important role in maintaining the proper functioning of the vehicle, which is why it is necessary to inspect the car’s brakes from time to time and replace them if necessary.

If you need to buy a car cover, it’s best to consider a few things.

The best way to choose the right crepe is to check the type used in the car you are considering.

If you are an automotive expert, you can determine the type of part by examining its crepe.

On the other hand, if you don’t have enough information about the crepe, you can take the car to a repair shop so that the crew can identify the type of crepe used.

When buying, pay attention to the quality of the crepe.

Try to identify well-known and experienced brands in the market and then make a purchase.

Because the car puts a lot of pressure on the crepe, if this equipment is not of good quality, it can break and cause serious damage.

Four unique elements that define every crepe:

نوع مواد(به عنوان مثال: گرید 10.9 و یا 8.8 
ابعاد پیچ و مهره(دندانه) (به عنوان مثال M24*3 میلی متر)
طول کرپی (به عنوان مثال: ۵0۰ میلی‌متر)
قطر مفتول  (به عنوان مثال: 24 میلی متر)
شکل کف کرپی بعنوان مثال: گرد

They are mainly used to fasten pipes to a metal surface. However, the bend of these screws varies depending on the profile and can be V-shaped or U-shaped.

If you look closely at the guardrails on the sides of bridges when crossing them, you will see a large number of U-bolts.

U-bolts are known as crepe screws in Iran. In fact, a crepe screw is a double-headed screw with a rib that has been bent.

In addition to the above, the experience of the crepe manufacturer also affects the quality of the final product.
