ISO 16582:2002

Overview

ISO 16582:2002 defines the specifications for open end blind rivets featuring a break pull mandrel and a protruding head. These rivets have a copper (Cu) body combined with a mandrel made of steel (St), bronze (Br), or stainless steel (SSt). The standard covers rivets with nominal diameters ranging from 3 mm up to and including 4.8 mm.

The document provides detailed dimensional and mechanical characteristics essential for manufacturers, engineers, and quality controllers to ensure consistent performance and compatibility in fastening applications. This standard plays a critical role in establishing uniformity in blind rivet design and testing, promoting reliability across industries.

Key Topics

• Dimensional Specifications: Defines exact dimensions for rivet body, head, shank diameter, grip ranges, and clearance hole diameters essential for proper fitting and function.

• Material Composition: Specifies copper rivet bodies combined with steel, bronze, or stainless steel mandrels. Surface finishes are also outlined, with natural finishes for copper and bronze parts and optional phosphate or zinc coatings for steel mandrels.

• Mechanical Properties: Sets minimum shear loads, tensile loads, and maximum mandrel break loads according to rivet diameter. Testing procedures reference ISO 14589 to ensure consistent mechanical performance.

• Mandrel Performance: Details requirements for mandrel push-out resistance and mandrel head retention capability to guarantee rivet integrity after installation.

• Workmanship and Quality: Establishes criteria for defect-free manufacturing, including burr-free surfaces and crack-free rivets after installation inspection under magnification.

• Designation and Identification: Provides standardized naming conventions for rivet types based on diameter, material, and length to facilitate ordering and documentation.

Applications

ISO 16582 rivets are widely used in various industrial and manufacturing contexts where durable, reliable blind fastening is required without rear access to the joint. Typical applications include:

• Automotive Industry: Assembly of body panels and interior components requiring robust fastening with corrosion-resistant materials.

• Electrical Equipment: Securing components where copper conductivity and corrosion resistance are beneficial.

• Machinery and Equipment Manufacturing: Fastening parts where vibration resistance and mechanical strength are critical.

• Construction and Metal Fabrication: Joining metal sheets and panels with consistent quality blind rivets.

The combination of copper bodies and diverse mandrel materials ensures these rivets can be adapted to specific environmental and mechanical requirements, such as corrosion resistance or strength.
