Slepá nit GESIPA PolyGrip® 4,0×10,0 mm hliník/nerez

Blind rivet GESIPA PolyGrip® 4.0×10.0 mm is a one-sided fastening element with an aluminum body and a stainless-steel mandrel. It is intended for use in applications where access is available only from one side and a corrosion-resistant joint is required. The rivet fits a 4.0 mm hole and provides a grip range suitable for material stacks up to 10.0 mm, making it compatible with thin sheet metal, plastic components and other thin-walled parts. The rivet is compatible with manual and pneumatic rivet tools designed for blind rivets.

Advantages

The combination of an aluminum body and a stainless-steel mandrel ensures a balance of light weight and increased corrosion resistance at the joint. The blind (one-sided) installation simplifies assembly in confined or inaccessible locations and reduces the need for component repositioning. Uniform clinching produces a reliable load-bearing connection with consistent setting characteristics. The rivet's dimensions and grip range support predictable performance across common sheet and panel thicknesses.

Suitable for

• Joining sheet metal panels and thin structural parts
• Fastening plastic housings and enclosures
• Repair and maintenance in automotive and industrial assemblies
• Applications where access is restricted to one side

Key specifications

• Body material: aluminum
• Mandrel material: stainless steel
• Hole diameter required: 4.0 mm
• Grip range (maximum material thickness): 10.0 mm
• Type: blind (one-sided) rivet

How to use

Drill or prepare a 4.0 mm diameter hole through the parts to be joined, ensuring hole alignment and cleanliness. Insert the rivet so the body passes through the hole and the rivet head sits flush against the outer surface. Position a compatible rivet tool over the exposed mandrel and operate the tool following the manufacturer's instructions until the mandrel snaps, indicating a set joint. Remove the broken mandrel remnants according to the tool's removal procedure and verify the formed blind head on the concealed side for secure fastening.

Recommendations

Use rivet tools rated for this rivet size and materials to ensure consistent setting force. When joining dissimilar materials, consider galvanic effects and, if necessary, use insulating washers or coatings. For critical or load-bearing applications, verify joint strength with a sample assembly and follow relevant industry standards for fastener spacing and edge distance.
