The main function of this pin is to fix two plates or shafts with blind holes on the shaft to form a solid connection.
Metal, plastic or composite materials can be used for blind hole fixings. The material to be selected varies depending on the application area and load carrying capacity.
Blind hole fixings are highly durable depending on the material and dimensions used. With the right material and assembly technique, they can exhibit long-lasting performance.
