Rebite cego GESIPA 5x20 mm flange grande, K14, intervalo de aperto 14,0–15,0 mm, embalagem de 250 unid.

GESIPA blind rivets 5x20 mm Large Flange, K14, designed for a 14.0–15.0 mm grip range, are single-sided fasteners supplied in a pack of 250. These blind rivets are intended for permanent joining where access is limited to one side of the workpiece. The large flange head increases bearing area to reduce pull-through when fastening softer or thinner materials, while the K14 specification denotes the rivet body and mandrel geometry engineered for reliable setting with compatible blind riveting tools.

Advantages

Large flange blind rivets deliver a wider contact surface that helps distribute load and minimise material deformation. The 5x20 mm size and K14 design provide consistent expansion and collapse during installation, ensuring secure joints in sheet metal, aluminium profiles, and composite panels. Supplied in a bulk pack of 250, they are convenient for production runs and on-site assembly, reducing the need for frequent restocking.

Suitable for

• Joining sheet metal and thin-gauge panels
• Fastening aluminium or plastic profiles
• Assembly of HVAC ducts and enclosures
• General construction and industrial maintenance

Key specifications

• Rivet diameter: 5 mm
• Rivet length (head to tail): 20 mm
• Head style: large flange
• Grip range: 14.0–15.0 mm
• Design: blind (single-side) rivet, K14 geometry
• Package quantity: 250 pieces

How to use

Select a compatible blind riveting tool and the appropriate nosepiece for a 5 mm rivet. Drill or prepare a hole sized to the rivet diameter, generally 5.0 mm, and insert the rivet through the assembled materials so the flange bears against the accessible surface. Place the tool over the mandrel and actuate until the mandrel breaks off and the rivet body forms a blind head on the blind side. Verify the formed blind head and ensure the flange sits flush without excessive deformation.

Recommendations

For best performance, use rivets within the specified 14.0–15.0 mm grip range and match the tool nosepiece to the 5 mm diameter. Pre-drill clean, correctly sized holes and avoid over-tightening or repeated re-setting of the same rivet. Store the pack in a dry location to prevent contamination that could affect setting quality.
