Blind Rivet (Closed Type)
Closed-type blind rivet for sealed permanent joints in thin-gauge sheet metal, sizes 3.2×8–4.8×25 mm. FLOK supplies it for shipbuilding and construction.
A closed-type blind rivet is a fastener that provides a strong permanent joint in thin-gauge sheet metal. This type of blind rivet is used to create sealed joints: since there is no hole in the body, the joint is protected against dust and moisture ingress.
Installation requires access to only one side of the joint and is performed using a special riveting tool. Installation is fast, and using this type of rivet is an alternative to welding.
Manufacturing features
The rivet body and mandrel are made of carbon steel; stainless steel and aluminium are also used. These materials are not subject to corrosion and can be used in environments exposed to moisture. Product specifications:
- Product size — from 3.2×8 to 4.8×25 mm.
- Thickness of the materials being joined — from 2 to 10 mm, depending on the body size.
- Rivets are installed in holes with a diameter of 3.3 to 5.9 mm.
Blind rivets are used in shipbuilding and other machine-building industries, and are also in demand in construction and other fields.
