Blind rivet GESIPA 4×8.0 mm Al/A2 CAP Standard, 500 pcs

Blind rivet GESIPA 4×8.0 mm Al/A2 CAP Standard, 500 pcs is a pack of closed-head pull rivets engineered for joining components where access is available from only one side. Each rivet has an aluminium body combined with an A2 stainless steel mandrel, providing a balance of light weight and corrosion resistance suitable for general fastening of thin sheets and mixed materials. The CAP (closed) head design produces a neat finished appearance on the visible side and creates a permanent mechanical joint once set.

Advantages

The aluminium body ensures low weight and good conductivity while the A2 stainless steel mandrel increases strength and rust resistance. The closed-head design delivers a tidy external finish and prevents mandrel protrusion after installation. Supplied in a bulk pack of 500 pieces, these blind rivets are convenient for workshop use and larger assembly runs, reducing downtime spent on frequent reordering.

Suitable for (tasks / use cases)

• Joining thin metal sheets and panels
• Assembly of lightweight structures and enclosures
• Fastening mixed-material joints (metal-to-plastic, metal-to-wood)
• Applications where only one-sided access is available
• Maintenance and repair tasks in workshops and production lines

Key specifications

• Rivet body material: aluminium
• Mandrel material: A2 stainless steel
• Rivet diameter: 4 mm
• Grip length / total length: 8.0 mm
• Head style: closed (CAP)
• Pack quantity: 500 pieces

How to use

Drill a correctly sized hole through both workpieces, then insert the blind rivet into the hole so the head sits flush on the visible side. Use an appropriate hand or pneumatic rivet gun compatible with 4 mm blind rivets and pull the mandrel until the body deforms and clamps the materials together. Once the mandrel breaks off, the joint is complete. Ensure the selected rivet grip length suits the combined material thickness for a secure connection.

Usage recommendations

For reliable results, verify hole diameter and combined material thickness before installation, choose a rivet gun rated for aluminium body/A2 mandrel rivets, and wear appropriate eye protection when setting blind rivets. Avoid use in highly corrosive environments where dissimilar metals could cause galvanic corrosion unless further protection or isolation is applied.
