The proven benefits that come with blind rivet technology are becoming recognised and employed by an increasing number of users: for example, in electrical engineering, vehicle construction, medical technology, mechanical engineering, household appliances, energy management, the toy and furniture industries, or even in the automotive and plant engineering sectors. Unlike welded joints, which cause the material to warp, rivets can be quickly installed on one side and with little heat. Even on hollow profiles and pipes, the joints are guaranteed to fit perfectly and maintain their dimensional accuracy.
TIFAS® closed end blind rivets have a cup-shaped sleeve that creates a closed and thus airtight, dust-tight and watertight footprint on the blind side. The high shear bearing resistance of TIFAS® closed end blind rivets makes for a very tight fastening. The mandrel remains securely retained in the sleeve. The stainless steel versions offer high corrosion resistance.
Airtight, dust-tight and watertight footprint
For suitably prepared holes, TIFAS® closed end blind rivets are exceptionally watertight in the field. For pressure-tight applications or retained media, an additional seal will be required between the rivet body and the bored hole in the component. Loose or mechanically fitted neoprene O-rings as well as TIFAS® closed end blind rivets with pre-applied sealant can be supplied on request.
A4 stainless steel TIFAS® closed end blind rivets
In keeping with the trend towards increasingly better-quality materials and finishes, TIFAS® closed end blind rivets are now available in A4 stainless steel. Although this version is especially used in plant and container construction, they are also put to use in marine applications, in shipyards, or in areas of power stations where safety is a major concern.
