A pull-out dowel pin is a cylindrical fastener with an internal thread at one end designed for easy removal using a bolt or a specialized tool. This design is beneficial in applications requiring frequent disassembly, especially in blind holes where standard pins are difficult to extract without causing damage.
Key Features
Design: Like standard dowel pins, they are precision-ground cylinders used for aligning and joining components and resisting shear forces.
Internal Thread: The internal threading allows a removal tool to be inserted to extract the pin.
Application: They are suitable for use in blind holes as they can be extracted without accessing the opposite side.
Venting: Some pins have a flat vent or a spiral groove to allow air or liquids to escape during installation in a blind hole.
Material and Hardness: They are typically made from durable, hardened materials like alloy steel or stainless steel for high shear strength and wear resistance.
