Used to connect the chain for a window actuator to a U-shaped window bracket.
The threaded end screws into a bolt hole (M5.5 female thread) on one side of the U-bracket. The tip of the fastener fits into a 3mm diameter slot on the other side.
The end of the chain pushes and pulls perpendicular to the axis of the fastener on the unthreaded section between the two connections.
Dimensions: Total length: 34mm. Threaded section length: 6mm. Unthreaded section: 3mm diameter. Threaded section: 5.5mm diameter.
What type of fastener is this, and how do I go about procuring a replacement, short of resorting to a bespoke service?
The unthreaded section can be thicker to some degree, or be threaded, as long as there is a 3mm diameter tip of at least 4mm length to connect to that side of the bracket.
For example, a M5.5 bolt with a 3mm diameter dogpoint would do the job. However, as far as I understand, there are no bolts standardized to a M5.5 diameter.
