Description/Basics
The screwed connection is one of the method most commonly used for detachable connections. Fulcrum pins, also called rotating bolts, have various advantages over conventional screws due to their hardened shaft.
The head of our rotating bolts is in part flatter than that of a stripper bolt, which, in combination with the various drive forms, simplifies the assembly in tight installation spaces. Similar to stripper bolts, Fulcrum pins have a tight-tolerance shaft that can be additionally hardened. This allows designing a simple bearing or guide.
When designing a swivel lock, a combination of Fulcrum pins and links are recommended. This allows, for example, to lock a solid closure. In this case, the rotary bolt can serve both as a bearing point and as an end stop. Its hardened approach offers suitable protection against premature wear in both functions.
Due to the ability to absorb transverse forces and shear forces, bearing bolts with hardened shoulders are suitable for creating a hinge assembly.
Combined with rod end bearings, there is also the option of balancing an offset.
