The Avdel Avbolt® heavy duty fastener is a structural blind fastener with high strength, and tamper resistance. Designed for use in heavy-duty fastening applications such as construction, container, railway, mining and bridge building.
Avbolt fasteners are ideal for areas with restricted access. They offer a fast, positive joint and provide the benefits of single-sided installation with minimal skill required. The Avbolt features a mechanical lock creating a vibration resistant joint and preventing loose stems. The Avbolt system offers ease of inspection for correct installation, excellent tamper resistance and an optimised hardness stem.
The fastener has been designed for applications in ship building, railway, automotive assembly including car seats, other ground transportation, mining equipment and construction
