How the System Works
Here’s how it works!!
The AKH FAS-NER SYSTEM® utilizes a unique, self-piercing fastener, called the AKH FAS-NER®, which mounts flush with the material being joined.
The AKH FAS-NER® is cylindrically shaped, having concave sides which resembles an hour glass. The AKH FAS-NER® is its own punch and is made of either hardened aluminum or high carbon steel.

Utilizing the tooling designed for the AKH FAS-NER SYSTEM®, the FAS-NER® pierces the material being joined.
|The lower die shears the material and allows the slug to pass through.||The FAS-NER®, being the same length as the total thickness of the materials being joined, takes the place of the pierced section.||The head on the top and the coining ring on the lower die tooling are forced around the FAS-NER® to permit the sides of the pierced hole to flow into and form around the concave section of the FAS-NER®.||The joint is locked tight and the FAS-NER® is flush with both surfaces of the assembly. The joint’s integrity depends on the characteristics of the combined materials and the proper selection of both tooling and FAS-NER®.|
