Blind rivet GESIPA 1454086 Al/St 5x16 mm countersunk head, grip 8.0–12.0 mm, pack of 500

GESIPA blind rivet 5x16 mm with a countersunk head and aluminium body combined with a stainless-steel stem is a fastener designed for flush mounting in sheet materials. With a grip range of 8.0–12.0 mm and supplied in a pack of 500, this rivet enables blind-side installation where access is available only from one side and a flush surface finish is required. It is suitable for joining metal, composite and coated panels while providing corrosion-resistant contact between the aluminum body and stainless stem.

Advantages

The countersunk head provides a flat, recessed finish that reduces protrusion and allows subsequent surface treatments or overlapping assemblies. The aluminium body keeps weight low and minimises the risk of galvanic corrosion on compatible substrates, while the stainless stem adds shear and tensile strength. Designed for blind installation, the rivet enables fast, repeatable assembly in production environments and maintenance operations.

Suitable for

• Joining sheet metal panels where a flush countersunk finish is required
• Assembly of composite and coated panels in industrial or transport applications
• Blind-side fastening where only one-sided access is available
• Repair, maintenance and retrofit tasks on enclosures, cabinets and bodywork

Key specifications

• Material combination: aluminium body with stainless-steel stem
• Head type: countersunk (flush) head
• Shank diameter: 5 mm
• Overall length: 16 mm
• Grip range: 8.0–12.0 mm
• Pack quantity: 500 pieces

How to use

Drill a clearance hole of the appropriate diameter for a 5 mm rivet through the assembled materials, ensuring countersink geometry if required for a flush finish. Insert the rivet from the visible side so the countersunk head sits flush with the surface, then use a suitable blind-rivet tool to pull the mandrel until the body deforms and forms a blind-side bulbed head. Continue pulling until the stem breaks off at its designed break point. Verify the clamping and that the head is seated flush and secure.

Usage recommendations

Choose a rivet tool and nosepiece matched to 5 mm diameter rivets and check tool condition to ensure consistent setting. For coated or thin materials, confirm hole edge and countersink quality to avoid paint or coating damage. Consider compatibility of aluminium and stainless materials with the substrates to limit galvanic interaction in exposed environments.
