Blind rivet GESIPA Al/St 3×5 mm for 1.5–2.5 mm sheets, pack of 500

Blind rivet GESIPA Al/St 3×5 mm is designed for reliable single-side fastening of thin materials. The rivet features an aluminum body and a steel mandrel, providing a combination of lightness and tensile strength suitable for sheets with thickness from 1.5 to 2.5 mm. Supplied in a pack of 500, this fastener is intended for repetitive assembly tasks in environments where access is limited to one side of the joint.

Advantages

The aluminum body reduces weight and minimizes corrosion risk on non-ferrous assemblies, while the steel mandrel delivers secure clamping force and consistent break-off performance. The 3×5 mm size is optimized for thin panels and ensures a flush or near-flush finish depending on installation technique. Packaged in bulk, the 500-piece quantity supports efficient workflow and reduces downtime for replenishment in production or on-site work.

Suitable for

• Joining thin sheet metal panels (1.5–2.5 mm thickness)
• Fixing plastic or composite panels where only one-side access is possible
• HVAC ductwork and metal ventilation components
• Vehicle body trim and lightweight structural attachments
• General assembly and construction tasks requiring repeatable blind fastening

Key specifications

• Material: aluminum body with steel mandrel
• Rivet size: 3×5 mm (diameter × grip length)
• Suitable sheet thickness: 1.5–2.5 mm
• Finish: unfinished aluminum body and steel mandrel (natural metal)
• Package quantity: 500 rivets

How to use

Select a matching rivet gun and mandrel nosepiece for a 3 mm rivet. Prepare holes in the components with the correct diameter and deburr edges if necessary. Insert the rivet through the aligned parts, place the mandrel into the rivet gun, and apply steady pressure until the mandrel snaps, forming the blind head and clamping the materials together. After installation, check that the rivet head sits flush and the joint is secure; replace the mandrel or nosepiece as recommended by the tool manufacturer.

Recommendations

For best results, verify material compatibility to avoid galvanic corrosion when joining dissimilar metals. Use clean, properly sized holes and maintain the rivet tool in good condition. Store rivets in a dry environment to prevent contamination or surface oxidation before installation.
