Blind rivet GESIPA PolyGrip® 4.8x17 mm Aluminum/Steel, 500 pcs

Blind rivet GESIPA PolyGrip® 4.8x17 mm in an aluminum body with a steel mandrel is a blind fastening element intended for permanent mechanical joining of thin sheets and assemblies when access is available from only one side. This pack contains 500 pieces and is engineered to deliver consistent setting quality and reliable joint strength across general assembly, metalwork and repair tasks. The combination of an aluminum sleeve and a steel mandrel provides a balance of light weight and structural integrity suitable for mixed-material applications.

Advantages

The PolyGrip® design ensures stable, reproducible joint formation with low expansion on the blind side and good clamping force. Aluminum body reduces overall weight and limits corrosion risk in many applications, while the steel mandrel supplies the tensile strength required for secure connections. Supplied in a bulk quantity of 500 pieces, these blind rivets support efficient workflow and reduced changeover frequency when used with compatible riveting tools.

Suitable for

• Joining thin metal sheets and light structural panels
• HVAC ductwork assembly and maintenance
• Automotive bodywork repairs and accessory mounting
• General production and maintenance fastening where one-sided access is required

Key specifications

• Material: aluminum body with steel mandrel
• Rivet head style: standard (flush/low-profile depending on application)
• Shaft diameter: 4.8 mm
• Shaft length: 17 mm
• Quantity: 500 pieces per pack
• Intended use: blind (one-side) fastening

How to use

Select a rivet size appropriate to the combined material thickness and hole diameter, then insert the rivet through the aligned parts from the accessible side. Use a compatible blind rivet gun to pull the mandrel until the rivet body deforms and clamps the materials together. Continue pulling until the mandrel snaps off, producing a formed joint. After setting, inspect the joint for full mandrel break and correct collar formation to ensure proper clamping and strength.

Usage recommendations

Use drills and hole sizes recommended for 4.8 mm rivets to ensure correct fit. Match the rivet to the total material thickness and consider surface treatment or sealing where corrosion resistance is critical. Store rivets in a dry environment and use appropriate rivet guns specified for aluminum/steel blind rivets to achieve consistent results.
