Releasable fastenings

The types of Dual Lock differ in the arrangement and number of heads. They can be freely combined and are suitable for different purposes depending on the combination. The heads slide over each other until they are audibly anchored together by pressure.  They can be connected straight, crossed, staggered or overlapped. The connections can withstand a lot and even with continuous vibrating movements they hold together firmly. Due to their thickness, they are often used to compensate tolerances.

Dual Lock fastening systems are available in three different mushroom head densities:

• DL 400 (400 heads/ inch²; 62 heads/ cm²)
• DL 250 (250 heads/ inch²; 39 heads/ cm²)
• DL 170 (170 heads/ inch²; 26 heads/ cm²)

Their greatest advantage, however, is that they allow re-releasable connections and remain invisible. This is especially important for components, claddings or covers that need to be quickly and easily detached and reattached for replacement during assembly, maintenance or repairs. The Dual Lock can be mounted on the back with the help of adhesive tape and is not visible from the outside, unlike screws or rivets. Its use allows enormous design freedom saves weight and speeds up the process. It is often used in the automotive sector, the furniture industry, mechanical engineering or in the advertising and decoration sector.
