Blind rivet GESIPA 6300928 Aluminum body / steel mandrel 5×8 mm for 2.5–4.5 mm panels

GESIPA blind rivet 5×8 mm with an aluminum body and steel mandrel is engineered for permanent fastening of overlapping sheets and components where access is available from only one side. The rivet’s 5×8 mm head profile and grip range for 2.5–4.5 mm panel thicknesses deliver a flush, vibration-resistant joint suitable for metalworking, HVAC, vehicle repair and general assembly tasks. Designed for use with standard blind rivet tools, this rivet allows rapid installation and consistent clamping force across batches.

Advantages

The combination of an aluminum body and a steel mandrel provides a balance of light weight and high shear strength, while the blind installation method eliminates the need for rear-side access. The specified grip range ensures reliable compression of panels between 2.5 and 4.5 mm thick, producing a neat, low-profile head on the visible side. The rivet resists loosening under vibration and delivers repeatable setting quality when used with compatible blind rivet tools.

Suitable for

• Joining overlapping metal sheets in fabrication and repair
• HVAC ductwork and panel assembly where rear access is limited
• Automotive bodywork repairs and non-structural vehicle components
• General industrial and domestic assembly tasks requiring blind fastening

Key specifications

• Body material: aluminum
• Mandrel material: steel
• Head size: 5×8 mm
• Grip range (suitable panel thickness): 2.5–4.5 mm
• Fastening type: blind rivet (one-sided installation)
• Typical applications: sheet metal, panels, assemblies subject to vibration

How to use

Drill a correctly sized hole through the overlapping materials, insert the rivet until the head sits flush against the visible surface, and place the mandrel into a compatible blind rivet tool. Squeeze or actuate the tool according to the manufacturer’s instructions until the mandrel breaks off and the formed tail clamps the materials together. Verify the rivet head is seated correctly and that the joint is tight and free of excessive gaps.

Recommendations

Use a blind rivet tool rated for the rivet’s mandrel diameter and material combination to ensure consistent setting. Select drill bit size to match the rivet body for a snug fit, and avoid over-torquing or excessive force when setting to prevent distortion of thin panels. Store rivets in a dry environment to limit surface corrosion prior to installation.
