Blind rivet GESIPA 1454121 Al/St 5×10 mm large head K14 KS 4.5–6.0 mm pack of 250

Blind rivet GESIPA 1454121 Al/St 5×10 mm large head K14 KS with a grip range of 4.5–6.0 mm is a one-sided permanent fastening element for joining sheets, profiles and mixed-material assemblies. The rivet combines an aluminum body and a steel mandrel to deliver a corrosion-resistant external appearance together with a strong, reliable core. Supplied in a pack of 250, these blind rivets are intended for use where access is available from only one side and where a large head is needed to distribute load over a wider surface.

Advantages

The aluminum shell provides good corrosion resistance and a light-weight connection while the steel mandrel ensures high shear and tensile strength at the joint. The large head design reduces the risk of pull-through on softer materials and increases bearing area for improved load distribution. Consistent dimensions and factory-set grip range simplify selection and speed up installation with common blind-riveting tools. Supplied in a bulk pack, the rivets reduce changeover time on production lines and support efficient inventory management.

Suitable for

• Joining metal sheets and profiles where only one-side access is possible
• Assemblies combining light alloys and steel components
• Applications requiring a larger bearing surface to prevent pull-through (e.g., thin or soft substrates)
• Production and repair work with power or hand-operated blind riveting tools

Key specifications

• Material: aluminum body with steel mandrel
• Nominal rivet size: 5 × 10 mm (diameter × length)
• Head type: large head (K14 KS style) for increased bearing area
• Grip range: 4.5–6.0 mm
• Pack quantity: 250 pieces

How to use

Select a rivet size and grip range that match the total material thickness to be joined. Drill a hole of the appropriate diameter through the workpieces, insert the rivet so the large head bears on the accessible surface, and position the mandrel into the nosepiece of a compatible blind-riveting tool. Activate the tool according to the manufacturer’s instructions until the mandrel snaps, forming a blind head and securing the joint. Inspect the finished rivet for correct deformation and ensure the mandrel break is clean and within specification.

Usage recommendations

Use corrosion-compatible materials or apply surface protection when joining dissimilar metals to minimise galvanic corrosion. For thin or soft substrates consider using a washer or choosing the large head profile to distribute load. Verify tool nosepiece compatibility with a 5 mm rivet diameter and perform a sample rivet to confirm correct grip range and setting force before full production.
