ISO15977 Aluminum Blind Rivets with Steel Mandrel
ISO 15977 Aluminum Open End Blind Rivets with Steel Mandrel consist of an aluminum alloy rivet body and a steel mandrel, providing a reliable solution for joining materials from only one accessible side. During installation, the mandrel is pulled through the rivet body to create a radial expansion, forming a secure mechanical joint without requiring access to the rear side of the assembly.
The combination of a lightweight aluminum body and a steel mandrel makes these blind rivets suitable for applications requiring a balance between weight reduction, installation efficiency, and mechanical strength. Available in various diameters, lengths, and grip ranges, ISO 15977 rivets are commonly used for sheet metal assemblies, equipment housings, electrical enclosures, automotive components, and general industrial products.
Specification:
The specification of ISO 15977 Aluminum Open End Blind Rivets with Steel Mandrel covers the main technical parameters required for proper selection and installation, including rivet diameter, rivet length, grip range, head style, mandrel material, and surface finish. These specifications determine the suitable material thickness range and joint performance after riveting.
ISO 15977 blind rivets are available with aluminum alloy bodies combined with steel mandrels in different sizes to meet various assembly requirements. Standard options include open end structure, dome head and large flange head designs, with different grip ranges available for joining thin sheets and components of various thicknesses. Rivets can be supplied with different finishes and customized specifications according to customer drawings or application requirements.

Dimension Chart of ISO15977 Aluminum Blind Rivets with Steel Mandrel:
The dimension chart of ISO 15977 Aluminum Open End Blind Rivets with Steel Mandrel provides detailed measurements for selecting the correct rivet size according to the thickness of the assembled materials. The chart includes key dimensions such as rivet diameter, rivet length, grip range, head diameter, head height, and mandrel dimensions.
Proper selection of rivet length and grip range is essential to achieve a secure joint after installation. The rivet body must provide sufficient expansion inside the assembly while maintaining proper clamping force between the connected components. All critical dimensions are controlled during production to ensure compatibility with standard riveting tools and consistent installation performance

Application:
ISO 15977 Aluminum Open End Blind Rivets with Steel Mandrel are widely used for assembling components where only one side of the workpiece is accessible. Small diameter sizes such as 2.4 mm and 3.2 mm are commonly used for thin sheet assemblies, electrical equipment, control cabinets, and lightweight enclosures, while larger sizes such as 4.0 mm, 4.8 mm, and 6.4 mm are suitable for thicker sheet metal parts, machinery covers, industrial equipment, and structural components requiring higher joint strength.
The aluminum rivet body provides a lightweight fastening solution, while the steel mandrel improves the expansion force and joint reliability during installation. These rivets are commonly applied in HVAC equipment, ventilation systems, metal fabrication products, automotive components, electrical appliances, and general industrial assemblies. Different aluminum alloys, rivet lengths, and grip ranges allow selection according to panel thickness, load requirements, and operating conditions.
