Slepý nit GESIPA 6300944, hliníkové telo oceľový tŕň, 5×12 mm, pre 6–8 mm dosky, plochá hlava

Blind rivet GESIPA 6300944 has an aluminum body combined with a steel mandrel and a flat head shape. With nominal dimensions of 5×12 mm, it is designed to form blind, one-sided fastenings in assemblies where access to the reverse side is limited. The rivet is specified for use with material stacks that produce a finished joint thickness suitable for 6–8 mm. It is commonly applied in construction, sheet-metal assembly and general fastening tasks where a vibration-resistant mechanical connection is required.

Advantages

The aluminum body provides corrosion resistance and reduced weight while the steel mandrel ensures controlled setting and reliable clinching. The flat head yields a low-profile finish on the accessible side and distributes load over a wider area compared with countersunk heads. Designed for blind installation, this rivet enables secure joints from one side without the need for access behind the workpieces, and its dimensions are suitable for typical panel and sheet thickness ranges.

Suitable for

• Joining aluminum, steel and composite panels with an overall thickness producing a 6–8 mm joint
• Sheet-metal fabrication and repair
• Construction and building envelope applications where one-sided access is required
• General assembly tasks in workshops and industrial maintenance

Key specifications

• Body material: aluminum
• Mandrel material: steel
• Head type: flat head
• Rivet diameter × grip length: 5×12 mm
• Recommended total material thickness (finished joint): suitable for 6–8 mm
• Application method: blind (one-sided) installation

How to use

Drill a hole of appropriate diameter through the parts to be joined, insert the rivet so the head sits flush on the accessible side, and position a compatible blind rivet tool over the exposed mandrel. Operate the tool to pull the mandrel until the rivet body expands and forms a blind head on the far side; the mandrel will break at its designed break point, leaving a secured joint. Ensure the hole is clean and properly aligned, and use a rivet setting tool rated for 5 mm rivets to achieve consistent results.

Recommendations

Use rivets of the specified 5×12 mm size for material stacks that produce the recommended 6–8 mm finished thickness. Select a hand or pneumatic rivet tool compatible with steel mandrels and observe standard safety procedures, including eye protection. For corrosion-sensitive installations, verify material compatibility between the aluminum body and mating materials or consider appropriate surface treatments.
