Rivetto cieco GESIPA 6301002, corpo in alluminio con mandrino in acciaio, 5×25 mm testa piatta

Blind rivet GESIPA 6301002 is a single-sided fastening element with an aluminum body and a steel mandrel, sized 5×25 mm with a flat head. It is intended for permanent joining of thin sheets and assembled components where access is available only from one side. The rivet provides a flush finish on the accessible side thanks to its flat head and offers reliable clamping in metal, plastic and composite materials when installed with a compatible blind rivet tool.

Advantages

The aluminum body combined with a steel mandrel delivers a balance of lightweight corrosion resistance and high mandrel strength during installation. The flat head gives a neat surface appearance and distributes load across the joint area, reducing the risk of pull-through in softer materials. Blind installation enables fast, repeatable assembly in areas with limited access, and the rivet is compatible with common hand and pneumatic blind rivet tools for efficient fitting.

Suitable for

• Joining thin metal sheets and panels in fabrication and repair
• Fastening plastic or composite components to metal frames
• Applications where only one side of the assembly is accessible
• Light- to medium-duty structural and enclosure assemblies

Key specifications

• Material: aluminum body with steel mandrel
• Nominal size: 5 mm diameter × 25 mm length
• Head type: flat head for flush finish
• Installation method: blind rivet (single-sided)

How to use

Drill or prepare a hole equal to the rivet diameter, align the parts to be joined, and insert the rivet through the stack so the flat head rests against the accessible surface. Fit a compatible blind rivet tool to the mandrel and operate the tool until the mandrel breaks off and the rivet body forms a secure blind-side bulge. Remove any broken mandrel remnants from the tool. Confirm that the joint is tight and the head sits flush; if not, replace the rivet and repeat the process with correct hole alignment and tool setting.

Recommendations

For best results, select a rivet length that allows proper blind-side deformation given the combined material thickness. Use a drill bit sized to the rivet diameter for clean holes and choose a rivet tool compatible with 5 mm rivets. Avoid overtightening or using a worn tool to prevent incomplete mandrel break-off or damaged heads; store rivets in a dry environment to maintain material condition.
