Flanged nuts

Flanged nuts are threaded fasteners with a bearing surface at the bottom of the body. The flange increases the contact area with the component and helps to distribute the force evenly during tightening. These nuts are used in assemblies where a stable threaded connection is required without the need for a separate washer.

The Dinmark catalogue offers flanged nuts in bulk for industrial enterprises, equipment manufacturers, construction companies and installation organisations. Fasteners of various sizes, strength classes and coating options are available for use in a range of conditions.

Characteristics of flanged nuts

The main distinguishing feature of a flanged nut is its integrated flange, which acts as a support washer. The larger contact area reduces the risk of surface indentation during assembly, particularly when working with sheet metal or thin-walled components.

Flanged nuts are primarily manufactured from carbon steel and are available with various anti-corrosion protection options:

• galvanised coating for use in standard conditions;
• coating with enhanced resistance to external influences;
• stainless steel for environments with high humidity or a risk of corrosion.

Flange nuts are available with various thread specifications – most commonly metric (M5–M16 and above, depending on the product series). Selection is based on the diameter of the bolt or stud, the strength class and the loads in the assembly.

In industrial applications, flanged nuts are used in accordance with international standards, in particular DIN and ISO. This means that flanged nuts can be easily combined with bolts and studs meeting the relevant standards, for the mass production of equipment and steel structures.

Types of flanged nuts – the Dinmark range

The Dinmark range includes flanged nuts for installation and manufacturing applications. Various designs are available:

• standard hexagonal flanged nuts;
• nuts with notches on the flange for better grip during tightening;
• products with different strength grades and coatings.

Flanged nuts are used in conjunction with bolts, studs and other threaded fasteners in assemblies where rapid assembly and a reduction in the number of components are required.

Before purchasing flanged nuts, it is advisable to select the thread size, material and coating in accordance with the operating conditions. Manufacturing companies can purchase flanged nuts in bulk, with delivery of the required quantities.

At Dinmark, you can also select components for threaded assemblies and order flanged connections together with the necessary fasteners.

Questions and Answers

Why is a flange needed on a nut?

A flange increases the contact area when tightening the nut. This reduces the point load on the component’s surface and helps to achieve a more stable connection. In many cases, a separate washer is not required when using such a nut.

Is a washer required for a flanged nut?

Under standard assembly conditions, a washer is not usually used, as the flange already fulfils its function. An additional component may be required if the design of the assembly or the technical specifications for assembly so require.

Where are flanged nuts used?

Flanged nuts are used in mechanical engineering, the automotive industry, the installation of industrial equipment, the manufacture of steel structures and repair work.

This type of fastener is often used in situations where rapid assembly is required and there is limited access for fitting a separate washer.

What is the minimum order quantity for delivery within Ukraine?

Dinmark works with industrial clients, manufacturers and wholesale partners, supplying fasteners in the required quantities. The terms of cooperation depend on the order volume, the type of fastener and product availability in stock.
