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.

Frequently Asked Questions (FAQ)
-
Question:
Why do fulcrum pins have a shaft?
-
Answer:
The shank of the fulcrum pin serves primarily as a bearing or pivot point. In addition, the hardened shank can be used as a stopper.
Another advantage may be that the assembly parts can be reduced by using the fulcrum pin with as a spacer.
-
Question:
Are the fulcrum pins offered comparable with the DIN 923?
-
Answer:
In principle, the fulcrum pin and the slotted drive from MISUMI are similar to DIN 923. However, the dimensions differ. For example, the head diameter of the pivot bolt from MISUMI is up to one millimetre larger.
-
Question:
What is the difference between a fitted screw and the socket with pin?
-
Answer:
A fulcrum pin has a less tightly tolerated shank than the shoulder bolts. Therefore, it is more suitable for simpler applications that are less focused on precision. Likewise, the length and diameter of the shank are not freely configurable for all fulcrum pins.
-
Question:
What does the M stand for in the specification of the nominal thread diameter?
-
Answer:
The code letter M indicates that the screw has a metric ISO thread. The metric ISO thread differs fundamentally from standard threads (rough threads) and fine threads. Assembly parts equipped with an M-thread and the same thread size are compatible with each other (example: M8 screw/M8 nut).
