Rivets

A rivet creates a permanent joint between two or more materials, while a Rivnut (threaded insert) installs into thin or soft material to provide a durable internal thread for a reusable bolted connection.

Yes. Blind rivets are designed for applications where access to the rear of the joint is limited or unavailable, allowing the fastener to be installed from one side.

Sealed rivets are used where the joint needs additional protection against water or environmental ingress. They are suited to applications where maintaining a sealed connection is an important consideration.

Semi-tubular rivets are an alternative rivet design used for specific assembly requirements where a full solid rivet is not necessary. Selection depends on the joint design, materials and required fastening performance.

Optimas International supplies breakstem, sealed, semi-tubular, Nylon, expansion, drive and scrivit rivets, as well as Rivnuts (threaded inserts). The appropriate type is selected according to factors such as joint design, material, access and fastening requirements.

Rivets and inserts are available in materials including aluminium, steel, stainless steel, brass and Nylon. Material selection depends on the joined materials, required strength, environmental conditions and application requirements.

Rivet selection typically considers factors such as rivet diameter, grip range, joined-material thickness and the required fastening performance. Optimas International can provide specification support to help identify a suitable solution for the application.

Relevant rivet standards include DIN 7337 and ISO 15977. Optimas International also operates to ISO 9001 quality standards, with PPAP Level 3 documentation available where required.

Optimas International helps manufacturers select rivets and Rivnuts based on the joint design, available access, joined materials and required fastening performance. We can support applications ranging from aircraft panels and sheet metal assemblies to wider industrial applications.
