Blind rivet

Blind Rivets: Technical Overview for Industrial Fastening

Blind rivets, also known as pop rivets or break-stem rivets, are permanent mechanical fasteners designed for joining two or more materials from one side when access to the rear is limited. They consist of a hollow rivet body and a mandrel (stem) that is pulled through the body to form a bulge on the blind side, securing the joint. Key technical parameters include rivet diameter (e.g., 3.2 mm, 4.0 mm, 4.8 mm), grip range (material thickness capacity), head style (dome, countersunk, large flange), and material composition (aluminum, steel, stainless steel, copper). The break load of the mandrel and shear/tensile strength ratings are critical for structural integrity. These fasteners are available in open-end and closed-end types, with closed-end variants offering sealing against liquids and gases.

Blind rivets are widely used in industrial sectors where access to the back of the workpiece is impossible or impractical. Common applications include automotive assembly (body panels, interior trim), aerospace (aircraft skin and interior components), HVAC ductwork, electrical enclosures, sheet metal fabrication, and general construction. They are also prevalent in the assembly of control cabinets, conveyor systems, and lighting fixtures. Their ability to join dissimilar materials (e.g., metal to plastic) makes them versatile in automated production lines.

Our catalog includes subcategories such as standard open-end blind rivets (e.g., aluminum body/steel mandrel), closed-end blind rivets for sealing applications, structural blind rivets with high shear strength, and multi-grip rivets that accommodate varying material thicknesses. Key article codes follow patterns like BR-AL-48 (aluminum, 4.8 mm diameter) or BR-SS-32 (stainless steel, 3.2 mm). Codes often include material abbreviation, diameter in tenths of mm, and head type indicator (e.g., D for dome, C for countersunk). We stock all standard sizes from 2.4 mm to 6.4 mm diameter.
