Blind rivet GESIPA 5×10 mm aluminium body steel mandrel flat head for 4.5–6 mm

Blind rivet GESIPA 5×10 mm aluminium body steel mandrel flat head for 4.5–6 mm is a single-sided fastener designed to form durable blind joints where access is available from only one side. The rivet combines an aluminium body with a steel mandrel and a flat head profile to deliver a secure, vibration-resistant connection in sheet assemblies and repair operations. It is intended for use in holes sized to accommodate 4.5–6 mm and produces a flush, low-profile finish suitable for visible surfaces and structural overlaps.

Advantages

The aluminium body reduces weight and offers corrosion resistance in many environments, while the steel mandrel ensures reliable setting and clinching during installation. The flat head provides a neat, low-profile appearance and distributes load across the mating surface. Designed for single-sided access, the rivet is compatible with standard blind-riveting tools and offers consistent performance in metalworking, fabrication and maintenance tasks.

Suitable for

• Joining metal sheets and panels
• Repairing bodywork and housings
• Assembling HVAC ducts and enclosures
• Fastening trims and brackets where back access is restricted

Key specifications

• Rivet body material: aluminium
• Mandrel material: steel
• Head type: flat head
• Rivet diameter and grip: 5×10 mm nominal
• Recommended hole diameter: for 4.5–6 mm holes
• Application: blind (single-sided) riveting

How to use

Prepare the mating parts and drill a hole sized for 4.5–6 mm according to the specified rivet diameter and material thickness. Insert the blind rivet through the aligned holes until the head sits flush against the workpiece surface. Use a compatible blind-riveting tool to pull the steel mandrel; continue applying force until the mandrel snaps and the rivet body deforms to form a blind head on the far side. After setting, remove the snapped mandrel stub if required by the tool and inspect the joint for correct compression and seating.

Recommendations

For optimal performance, select a rivet length that matches the total material thickness and ensure the hole is clean and properly deburred. Use a rivet tool rated for aluminium-body/steel-mandrel rivets and perform a sample installation to confirm fit and grip before production or large-scale assembly.
