Rebite cego GESIPA 6300138 corpo de alumínio, mandril de aço, 3×6 mm, para espessuras 2,5–3,5 mm, cabeça chata

Blind rivet GESIPA 6300138 features an aluminum body and a steel mandrel, sized 3×6 mm and intended for joining materials with a combined thickness of 2.5–3.5 mm. The rivet has a flat head profile that yields a low, flush finish on the visible side and allows installation from the blind side when access is only available on one face. This fastener is designed for use in sheet metal assembly, light structural joins and general repair tasks where a durable, vibration-resistant joint is required.

Advantages

The aluminum body offers corrosion resistance and reduced weight while the steel mandrel ensures secure setting and consistent break-off. The flat head provides a neat, low-profile appearance and distributes clamping force over a wider area. Designed for blind installation, this rivet produces reliable joints in applications where access is limited to a single side and where a flush exterior is preferred.

Key specifications

• Body material: aluminum
• Mandrel material: steel
• Dimensions: 3 × 6 mm (diameter × grip length)
• Recommended material thickness range: 2.5–3.5 mm (combined)
• Head type: flat head (low-profile)
• Suitable installation method: blind-side setting with rivet tool

How to use

Drill or prepare a hole of appropriate diameter through the materials to be joined. Insert the rivet into the hole with the mandrel protruding, place the rivet tool over the mandrel and actuate the tool according to the manufacturer's instructions until the mandrel snaps. After mandrel break-off, confirm that the rivet body has formed a secure blind-side bulge and that the head sits flush against the visible surface. Remove any metal shavings and inspect the joint for proper compression and alignment.

Recommendations

Use a rivet tool compatible with 3 mm rivets and rated for aluminum-steel combinations. Verify the combined material thickness falls within the 2.5–3.5 mm range before installation. For best corrosion resistance, avoid direct contact between dissimilar metals in corrosive environments or use appropriate coatings or isolation materials. Wear eye protection and follow standard safety practices when drilling and setting blind rivets.
