Blind rivet GESIPA 5x12 mm countersunk head KS for 6.0–8.0 mm materials, pack of 500

Blind rivet GESIPA 5x12 mm countersunk head KS is a one-sided mechanical fastener designed for joining two or more workpieces with a combined material thickness of 6.0–8.0 mm. The countersunk head provides a flush finish when installed, making it suitable for visible surfaces where a flat seating is required. Supplied in a pack of 500, these blind rivets are intended for applications where access to the backside of the joint is limited or impossible.

Advantages

These blind rivets offer reliable, vibration-resistant fastening with consistent clamp and grip for the specified material range. The countersunk head reduces snagging and produces a neat, flat surface after installation. Packaged in bulk, the set of 500 reduces frequent reordering for production or repair tasks and supports efficient, uninterrupted fastening operations.

Suitable for

• Sheet metal assembly and repairs
• Electrical enclosures and panels where a flush surface is required
• Metalwork and structural fastening in confined or one-sided access situations
• Appliance and equipment manufacturing where aesthetic flush finish is needed

Key specifications

• Rivet diameter: 5 mm
• Rivet length: 12 mm
• Head type: countersunk (KS) for flush seating
• Suitable total material thickness: 6.0–8.0 mm
• Pack quantity: 500 rivets
• Threadless blind rivet design for one-sided installation

How to use

Prepare the materials by aligning the components and drilling a matching 5 mm hole through the stack. Insert the blind rivet into the hole so the countersunk head sits flush with the outer surface. Using a compatible blind rivet tool, draw the mandrel until the rivet body deforms and forms a secure blind-side bulge. Continue pulling until the mandrel snaps, then remove the mandrel piece. Verify that the head sits flush and that the joint is securely compressed within the specified grip range.

Recommendations

Use a rivet tool suitable for 5 mm diameter blind rivets and verify mandrel compatibility before installation. Ensure hole diameter and material thickness match the rivet specifications to achieve proper clamping force. For best results on thinner or softer materials, consider using backing or washers only if the countersunk finish can be maintained. Store rivets in a dry area to avoid surface corrosion prior to use.
