Blind rivet GESIPA 6700152 4.8×15 mm — aluminum body, steel mandrel, PolyGrip

Blind rivet GESIPA 6700152 is a 4.8×15 mm blind fastener with an aluminum body and a steel mandrel, featuring GESIPA's PolyGrip design. It is designed for one-sided installation where access is available only from the front, making it suitable for joining thin to medium-thickness sheets and assemblies. The aluminum body provides a corrosion-resistant contact surface while the steel mandrel ensures high clamping force and secure joint formation.

Advantages

The combination of an aluminum sleeve and a steel mandrel delivers corrosion-resistant external contact with a strong, ductile core for secure pull-through during installation. The PolyGrip design improves mandrel seating and joint stability, reducing the risk of mandrel breakage or incomplete set. The 4.8×15 mm size covers a common range of material thicknesses and offers predictable grip performance for repeated blind riveting tasks.

Suitable for

• Blind fastening of sheet metal panels and enclosures
• Assembly of HVAC ducts, cable trays and light structural frames
• Joining thin to medium materials such as aluminium, steel and coated substrates
• Applications where access is available from one side only

When it may not be suitable

This rivet may not be appropriate for very thick materials or heavy structural joints that require larger-diameter or solid rivets, bolts, or threaded fasteners. It is also not intended for applications that demand fully non-magnetic fasteners because the steel mandrel introduces magnetic properties.

Key specifications

• Rivet overall diameter: 4.8 mm
• Rivet length: 15 mm
• Body material: aluminum (corrosion-resistant contact)
• Mandrel material: steel (high-strength pull-through)
• Design feature: PolyGrip mandrel seating for improved joint stability
• Intended sheet thickness range: suitable for thin to medium thickness assemblies

How to use

Select the 4.8×15 mm rivet when the combined material thickness falls within the recommended grip range for this size. Drill or prepare a clearance hole matching the rivet diameter, insert the rivet from the accessible side, and place the mandrel into a compatible blind rivet tool. Operate the tool until the mandrel breaks off and the rivet body forms a secure bulbed tail on the blind side. Inspect the formed joint to ensure proper clamping and absence of deformation that could compromise the assembly.

What to consider before purchase

• Confirm the combined material thickness fits the 4.8×15 mm rivet grip range
• Ensure corrosion compatibility between aluminum body and mating materials
• Check that a rivet tool compatible with 4.8 mm mandrels is available
• Consider whether steel mandrel magnetic properties are acceptable for the application

Usage recommendations

Use a rivet gun rated for the rivet diameter and maintain consistent tool stroke to achieve uniform joints. Store rivets in dry conditions to prevent contamination and verify hole alignment before setting to ensure optimal PolyGrip performance and reliable blind fastening.
