Nit GESIPA 1433614 Al/A2 5x12 mm veľká hlava K14 KS 6,0–8,0 mm, 250 ks

Blind rivets GESIPA 1433614 are aluminium-bodied fasteners with a stainless-steel mandrel, designed for permanent blind-side joining. The rivet measures 5×12 mm and features a large head (Grosskopf) K14 KS, which provides an increased bearing surface for softer or thinner materials. These blind rivets are intended for applications with a total material thickness of 6.0–8.0 mm and are supplied in a pack of 250, offering a consistent, corrosion-resistant connection where access is available only from one side.

Advantages

The aluminium body combined with an A2 stainless mandrel ensures corrosion resistance and reliable strength in mixed-metal assemblies. The large head distributes load over a wider area, reducing pull-through on thin or soft substrates. Designed for blind installation, these rivets allow quick, repeatable installation with common pneumatic, manual, or battery-powered rivet tools. Packaged in quantities of 250, they are suitable for medium- to large-scale projects and reduce downtime from frequent reloading.

Suitable for

• Joining thin sheet metal and light-gauge panels
• Assembling components where access is limited to one side
• Applications requiring corrosion resistance in mixed-metal joints
• Industrial or maintenance tasks with medium-volume fastening

Key specifications

• Body material: aluminium
• Mandrel material: A2 stainless steel
• Rivet diameter × length: 5 × 12 mm
• Head type: large head (Grosskopf) K14 KS
• Suitable total material thickness: 6.0–8.0 mm
• Pack quantity: 250 pieces

How to use

Select a rivet with the correct diameter and length for the combined thickness of the joined materials. Drill or prepare a matching 5 mm hole through the parts to be joined. Insert the rivet into the blind hole so the flange sits flush against the visible face, then position the rivet tool over the exposed mandrel. Operate the rivet tool according to the tool manufacturer’s instructions until the mandrel snaps and a secure blind head forms on the inaccessible side. Verify the formed blind head and seating of the rivet head; replace any rivet that did not form correctly.

Recommendations

For optimal performance, use rivet tools rated for 5 mm aluminium rivets and ensure the workpieces are clamped to avoid misalignment. When joining dissimilar metals, confirm that the aluminium body and stainless mandrel combination suits the environment to minimize galvanic corrosion. Store unopened packs in a dry place and handle rivets with clean tools to avoid surface contamination that could affect corrosion resistance.
