What is Rivet?

Rivets used to combine multiple materials in a strong and economical way are often referred to as "blind rivets", as you can perform the assembly process without having to see the back of the material. These powerful and economical fasteners, which are used in many fields from the automotive industry to the energy sector, are produced in different sizes, materials and shapes according to the area they will be used and the load they will carry.

(See Chapter 11) Product Selection)

What is Nut Rivet?

It is a fastener used to combine materials with bolts that are thin enough to open teeth. The teeth of the nut rivet work like a nut welded to the material to which it is applied. Using a Nut Rivet, you can also make the materials that you cannot reach the back of the nut with nuts.

A very strong join can be achieved by using nut rivets in materials where it is not possible to open teeth or the teeth to be opened will not be strong enough. – Click here for detailed information

Which Product Should I Use?

Our products produced in DIN7337, ISO and RoHS Norms can be used in many different areas. Some sectors we serve; industrial kitchen systems, cooling systems, white goods production, façade dressing, electronics and defense industry. Different rivet types are available according to the sectors and materials to be combined. While stainless steel or all aluminum products are preferred in the food sector, heavy-duty products consisting entirely of steel are preferred in the automotive field. Our technical team will help you free of charge and provide technical support to choose the right product for your production process. Please click here for more of the article

Rivet Types by Tightening Type

Standard Pop Rivet

When the rivet is tightened, the rivet is formed in a spherical shape on the back of the joined part, providing the join.

Multigrip Rivet

On the back of the joined part, the rivet takes a 2-3 muffled shape and is combined. The tightening range is wide rivets.

Back Closed Rivet

When the rivet is tightened, a closed surface is formed on the back of the joined part, which interrupts the contact of air and liquid.

.

Octopus Rivet

The back of the joined part is divided into 4 parts, providing joining. The remaining part at the back is preferred if it is a fragile/soft material.

Bulb Rivet

When the rivet is tightened, the join is provided by taking the shape of a flake on the back of the joined part. Sealed bulb rivets have a sealed feature.

STANDARD BOMBE-HEADED POP RIVETS

pop-percin1Standard pop rivets are the most economical method for permanentand easy merging of metal parts. Our products produced in accordance with DIN7337 norms by cold method in special fully automatic eccentric presses provide an aesthetic appearance on the combined surface while providing a solid port.

They are also called "blind rivets" because pop rivets can be processed without seeing the back of the material to be combined with when using them.

Main Features:
– Allows installation with only one side of the material,
– Wide diameter option, – Does not
deform the surface during riveting,
– Resistance to temperature changes, – Does
not loosen in exposure to dynamic stresses such as vibration,
– Fast, simple and high-quality joining,
– The joining process is environmentally friendly and does not scatter dust, particles, parts that put work safety at risk.

STANDARD BY MATERIAL TYPE

BOMB HEAD RIVETS

STANDARD POP RIVETS WITH A BARK HEAD AND WIDE HEAD

We also produce our standard pop rivet products with a counterhead and a wide head.

When to Choose Wide-Headed Rivets

Wide head rivets, the material on the front of the parts to be assembled, such as wood and plastic, can be preferred if it is a softer material than metal.

Counterhead Rivets

It can be used to achieve a flat surface after application.

STANDARD RIVETS WITH BARK AND WIDE HEAD

Which Size Rivet Should I Use?

multigrip rivetThe ideal rivet length selection to be used in your project is obtained by calculating the thickness of the material to be squeezed and the sum of the rivet diameter you will use.

For example, if you want to use Material thickness to be combined = a = 10mm
Rivet diameter = b = 4.8mm
Rivet length = a + b = 10mm + 4.8mm = 14.8mm
∴ You need to choose a rivet with a length of at least 15mm.

Note: When measuring the length of the rivet, the head and nail are not taken into account.

In octopus rivets, this calculation is made by multiplying the rivet diameter by 2 (two).

For example, if you want to use Material thickness to be combined = a = 10mm
Rivet diameter = b = 4.8mm
Rivet length = a + (2 x b) = 10mm + 9.6mm = 19.6mm
∴ You need to choose a product that is at least 20mm long.

You can visit the MULTİGRİp PRODUCT PAGE on the tightening ranges of the multigrip product line, which provides successful riveting with the use of the same size rivet in both thin and thick materials.

What should be the hole diameter in the material?

For an ideal connection process, the hole diameter in your material is as important as the quality of the rivet you use. An oversized hole can cause your anchor point to be weak or, in the long run, the rivet to break. For detailed information about the Appropriate Hole Diameter for Riveting, please refer to our Appropriate Hole Diameter article

How to Understand Quality Pop Rivet?

When we started to produce pop rivets in Turkey, the market was dominated by products made of pipes. A standard capsule is made of aluminum wire filled with special alloys. Special automatic cold form machines cut filled aluminum wire of appropriate length; by hitting the cut aluminum wire part with great pressure, pushing the material inside the wire to the outside by plastering it into a hat (flander). The nail is also made of special alloy steel wire.

After the produced body and nail are cleaned from the oils and undergo special surface treatments, they are combined in fully automatic joining machines.

How to Understand a Poor Quality Product?

The poor quality pop rivet is produced by cutting non-alloy aluminum pipes instead of filled aluminum wire and curling the head with a simple press. That's why the hat parts are irregular. There is no angle of 90 at the junction of the hat part with the body. The robust and long-lasting of the joining process depends on the alloy of the aluminum used and the strength of the plastering style production.

Unqualified rivets tend to break even in very small vibrations. The savings you try to make in small quantities by using poor quality fasteners in your production; we will return to you as product dissatisfaction, customer, TIME and money loss.

You can select and order a variety of rivets with different features and structures based on your usage areas through our Web site. For 30 years, we have been manufacturing and selling different rivets for use in various fields. Depending on the types and usage areas of the products you will combine, you can choose the product that suits you from our site or you can get technical information about product selection from our company.
