Rivets

Rivets are used to join sheet materials, profiles and components in construction and manufacturing. During installation, the rivet body deforms, forming a closing head and securing the components together. This fastening method allows structures to be assembled without welding, while blind rivets can be installed with access from only one side.

The DINMARK catalogue includes rivets in various designs and materials. The choice depends on component thickness, loads, operating conditions and installation method.

Types of Rivets and Their Features

Each rivet type has its own purpose and installation requirements. Before purchasing, determine whether you need a permanent joint between components or a threaded fastening point for subsequent assembly.

Blind rivets consist of a body and a mandrel. The riveting tool pulls the mandrel, deforming the body on the reverse side of the components, after which the mandrel breaks at a predetermined point. The main advantage is installation without access to the back of the joint. Products differ in body and mandrel materials, head shape and grip range.

Solid rivets are installed by deforming the end of the shank to form a closing head. This usually requires access from both sides: a backing support is placed on one side, while the head is formed on the other using a suitable tool.

Rivet nuts create an internal thread in thin sheet material or a profile. Once installed, they accept a screw or bolt. The nut itself remains secured in the base material, while the attached component can be removed and reinstalled.

Special-purpose rivets are used for applications with additional requirements, such as fastening soft materials, providing a larger bearing area or sealing the joint. Check the documentation for the specific product to confirm the required properties.

Where and Why Rivets Are Used

Riveted joints are used in mechanical engineering, metal enclosure manufacturing, ventilation installation, cladding and other structures. They are convenient for assembling thin sheet components when welding is impractical or access to the fastening point is limited.

Typical applications include:

• joining metal sheets and profiles;

• assembling covers, panels and equipment enclosures;

• fastening ductwork components;

• installing cladding components;

• creating threaded fastening points in thin walls using rivet nuts.

For manufacturing businesses, purchasing rivets in bulk according to a specification helps ensure that assembly operations have the required sizes and supports inventory replenishment planning.

How to Choose the Right Rivets

Joint reliability depends on matching the fastener to the components and loads. Identical external dimensions do not mean identical performance characteristics.

Determine the joint type. Choose suitable rivets for permanently joining components. If the attached component needs to be removed later, consider a rivet nut with a screw or bolt.

Consider the component materials. Select the fastener material according to strength, corrosion resistance and compatibility with the base material. For blind rivets, check both the body and mandrel materials: “aluminium/steel” and “aluminium/aluminium” indicate different versions.

Check the total material thickness. The combined thickness of the components being joined must fall within the rivet’s grip range. For a rivet nut, consider the thickness of the base material in which it will be installed. Body length alone is not a sufficient selection criterion.

Select the diameter and head type. Choose the diameter according to the loads and joint geometry. A large head distributes the clamping force over a greater area, while a countersunk head requires appropriate surface preparation.

Follow the hole requirements. The hole size and shape must comply with the manufacturer’s documentation. Excessive clearance or burrs can compromise installation quality.

Check tool compatibility. The riveting tool must support the required fastener type, material and size. For rivet nuts, the correct threaded mandrel and installation force or stroke settings are also important.

When buying a replacement rivet, check its characteristics against the joint specification. Selecting a fastener based solely on visual similarity can lead to errors.

Buy Rivets in Ukraine: Prices and Ordering

Rivet prices depend on design, materials, dimensions, protective coating and purchase volume. Special-purpose versions may differ in price from standard products, even when the diameter is the same.

When comparing offers, check the pricing unit: prices may be quoted per piece, per hundred or per pack. Also consider pack sizes, available quantities and lead times.

To buy rivets in bulk, prepare a list of the required items with the following details:

• type or standard;

• body and mandrel materials for blind rivets;

• diameter, length and grip range;

• head shape;

• thread size for rivet nuts;

• quantity.

When sourcing a specific rivet, compare prices for the same version. For regular purchasing, order rivets in bulk according to an agreed specification, allowing substitutions only after technical approval.

Advantages of Buying on the Dinmark B2B Platform

The DINMARK B2B platform helps organise rivet purchasing for manufacturing, installation and project supply. The catalogue allows you to select the required version and check the listed specifications and supply terms.

When preparing an order, you can:

• compare fastener sizes and materials;

• check prices for selected items;

• take the stated dispatch times into account;

• clarify specifications with the DINMARK team;

• manage orders in your B2B account.

Before placing an order, check that the selected item matches your specification and confirm the required order multiples. If you need to buy rivets for a new application, prepare information about the base material, component thickness and joint requirements to help identify the appropriate version more accurately.

Questions and Answers

What Is the Difference Between Blind Rivets and Rivet Nuts?

A blind rivet directly fastens components together, creating a permanent joint. A rivet nut creates an internal thread in the base material for a screw or bolt. The component attached to it can be removed by unscrewing the threaded fastener, while the nut itself remains in the base material.

Can Rivets Be Used for Outdoor Structures?

Yes, provided the material and design are suitable for the operating conditions. Consider atmospheric moisture, salts, industrial pollutants and metal compatibility. For blind rivets, both the body and mandrel materials matter. If a watertight joint is required, choose a suitable special-purpose version and check the sealing requirements for the entire assembly: a standard rivet does not guarantee protection against leaks.

Is a Special Tool Required to Install Rivets?

Blind rivets require a compatible manual, cordless or pneumatic riveting tool. Rivet nuts require a tool with the appropriate threaded mandrel. Solid rivets are installed using a backing support and a tool for forming the closing head. Select the equipment according to the fastener type, size and material.

What Determines the Cost of Rivets in a Bulk Order?

The cost of rivets depends on their design, materials, dimensions, coating, quantity and supply terms. Pack sizes and the mix of items in the order also affect the total amount. To compare offers accurately, use the same specification and check the quantity covered by the quoted price.
