HONSEL ALFO® FLEX blind rivets have been specially optimised for often problematic riveting in very soft materials or with slightly too large drill hole diameters. Due to the thinner wall thickness of the blind rivet sleeve, less force is required to deform the blind rivet sleeve. This improved deformation leads to a higher residual rivet mandrel locking. A thinner wall thickness of the blind rivet sleeve also means less influence on the hardening fluctuations caused by the annealing process. Result: The riveting function is much more consistent compared to conventional rivets. On request, the material combinations steel/steel and stainless steel/stainless steel (A2 and A4) are available as flat, countersunk or large heads. large head with a corresponding minimum quantity. Why ALFO® FLEX . Compensation for excessively large drill holes . improved residual mandrel locking . lower breaking forces . less wear on the tool . higher clamping force . ideal for soft material

The classic model. The designation ALFO® stands for the product range of HONSEL open standard blind rivets that are available with dome, countersunk or large dome head. It covers the versions and special types described in DIN EN ISO 15977 to 15984 as well as 16582 and 16584. “Special types” by our definition are rivets with a function as described in the above standards, but with differences in certain dimensions, functional properties or material combinations.

CERTO® – The Leak-tight Thanks to their cup-shaped rivet sleeves, CERTO® sealing blind rivets are the specialists when it comes to liquid-tight riveting. Thanks to this special design, the breakstem is also captive. The rivet forms a smooth, burr-free blind head and is suitable for automatic riveting. Blind rivets are one of the most extensively used fasteners worldwide. An almost endless diversity of types, sizes and formats ensure solutions for all applications. For years, HONSEL has focused primarily on the manufacture of non-standard blind rivets.

The OPTO multigrip blind rivet with his especially embossed rivet shaft, is distinctly different to a standard blind rivet. Due to his constructive structural, the rivet guarantees lots of excellent performance characteristics: — large grip range — good filling capacity of the borehole — non-positive locking of the captive mandrel without clearance — no rattling sounds — dustproof and splash water-tight Preferred applications for OPTO multigrip blind rivets can be found in the field of vehicle manufacturing, in air conditioning technology as well as in the production of tanks and cntainers. Furthermore, this rivet type is excellently suited for use as a repair rivet. Honsel develops for this blind rivet type special variants for the serial producti on, too, e. g. large grip range low grip range with a diameter up to 8,0 mm!
