Blind rivet GESIPA 1454123 Al/St 5x16 mm large flange K14 for 10.0–12.0 mm, pack of 250

GESIPA blind rivet 1454123 is a blind rivet with an aluminium body and steel mandrel (Al/St), sized 5x16 mm with a large flange (Grosskopf) and K14 head form. It is specified for joining material stacks with a combined thickness of 10.0–12.0 mm and is supplied in a pack of 250 units. The design delivers a broad bearing surface from the large flange, making it suitable for fastening applications where load distribution and resistance to pull-through are required.

Advantages

The aluminium body provides corrosion resistance and lightweight performance while the steel mandrel ensures reliable setting and permanent clamping. The large flange increases bearing area to reduce material deformation and pull-through on softer substrates. Pack quantity of 250 supports production runs and maintenance tasks, and the K14 head geometry is compatible with standard blind rivet tools designed for closed-head installation.

Suitable for

• Permanently joining thin metal sheets and mixed-material assemblies
• Fastening on materials that require a larger bearing surface to prevent pull-through
• Applications with combined material thickness of 10.0–12.0 mm
• Production, assembly, and repair tasks requiring medium-volume rivet supply

Key specifications

• Body material: aluminium
• Mandrel material: steel
• Rivet diameter: 5 mm
• Rivet length: 16 mm
• Flange type: large flange (Grosskopf)
• Head type: K14
• Recommended grip range (material thickness): 10.0–12.0 mm
• Pack quantity: 250 pieces

How to use

Drill a hole of correct diameter through the components to be joined, ensuring alignment and clean edges. Insert the rivet so the large flange rests against the outer surface. Use a compatible blind rivet tool suitable for 5 mm rivets and K14 head forms, place the tool nose on the mandrel, and actuate the tool until the mandrel breaks off and the rivet body forms a blind-side bulb. Verify that the flange sits flush and the joint is secure; trim or deburr as necessary.

Recommendations

Store rivets in a dry environment to prevent surface contamination. Select drill diameter and tool nosepieces that match the 5 mm rivet size and K14 head geometry. For dissimilar materials, consider galvanic compatibility and use appropriate surface treatments or isolation layers where necessary.
