Wide-Flange Blind Rivet

Wide-flange blind rivets are a type of fastener for creating a strong permanent joint of sheet materials. The increased flange diameter creates higher clamping force when fixing the material, making the joint stronger. A metal mandrel with a head and serrations runs through the large-diameter flanged body.

During installation, the mandrel is pulled by a rivet gun and deforms, and the fastener is firmly secured in the hole. The products are intended for single use.

Features and materials

The main purpose of the rivets is to firmly fix materials with even distribution of clamping force, which is why the fastener is fitted with a wide flange. This type of fastener is suitable for installing fragile materials: the increased flange size reduces pressure on the surface and protects the material from cracking.

Possible material combinations:

• Body and mandrel made of stainless steel — increased strength and corrosion resistance.
• Body made of aluminium, mandrel made of steel.
• Body made of steel, mandrel made of aluminium or aluminium alloy.
• Body and mandrel made of aluminium — the non-ferrous metal is not subject to corrosion, and the rivets withstand exposure to aggressive environments over the long term.

The rivets are produced in a wide range of sizes, so a variant can be selected for joining materials of different thicknesses. Selection takes into account the mandrel length and the body diameter of the rivet.

Applications

This type of fastener is in demand in mechanical engineering, machine-tool manufacturing, and industrial equipment production. In construction, the increased flange allows the rivets to be used for fastening facade materials and assembling ventilated facades. The fastener is also suitable for other tasks.
