Heavy-Duty Steel Blind Rivet with Countersunk Flange

Heavy-duty steel blind rivets are a special type of fastener used to create permanent joints between sheet metal parts. The fastener forms joints resistant to tensile and shear loads, and can be installed with access from one side only.

A special tool — a rivet gun — is used for installation. The fastener consists of a body and a mandrel, both made of high-strength St steel. It is installed into a hole pre-drilled in the material, with a diameter slightly larger than the mandrel diameter.

Specifications

The body and mandrel of the heavy-duty rivet are made of St steel, a material capable of withstanding significant loads. The products have the following characteristics:

• The thickness of the materials being joined depends on the mandrel length and ranges from 3.17 to 12.07 mm.
• The size can be 4.8 or 6.4 mm.
• Tensile strength — from 5.4 to 10.1 kN.

Applications

Heavy-duty rivets are designed for high tensile and shear loads. They are used in various branches of mechanical engineering: instrument making, machine tool building, the automotive industry, and others. They are used as an alternative to welding when creating permanent joints with access from one side only.
