A knurled dowel pin is a type of dowel pin that features a textured or knurled surface along a portion of its length. The knurling provides additional grip or friction, making it easier to handle and insert the dowel pin into its designated hole. This design is particularly useful in applications where manual insertion or removal of the dowel pin is required.
Key features of knurled dowel pins include:
1. Cylindrical Shape: Like standard dowel pins, knurled dowel pins have a cylindrical shape. The cylindrical body allows them to fit into corresponding holes or bores in the components being joined.
2. Knurled Surface: The knurled section is a part of the dowel pin where a pattern of raised ridges or grooves has been created. This textured surface provides better grip, facilitating manual handling and insertion without the need for specialized tools.
3. Precision Dimension: Knurled dowel pins, like other dowel pins, are manufactured with precise dimensions to ensure accurate alignment and a secure fit between the joined components.
4. Smooth Unknurled Ends: Typically, the ends of knurled dowel pins remain smooth to facilitate easy insertion into the aligned holes without causing damage to the components.
5. Material Options: Knurled dowel pins can be made from various materials such as steel, stainless steel, or other alloys, depending on the specific application requirements.
6. Applications: The knurled design is advantageous in applications where a secure grip is needed during manual assembly or disassembly. It is often used in fixtures, jigs, and assemblies where precision alignment is crucial.
The knurled dowel pin's textured surface enhances its usability in situations where fingers or tools are used for handling, especially when precise alignment is essential. These dowel pins are commonly found in industries such as manufacturing, automotive, aerospace, and electronics, contributing to the efficiency and reliability of assembly processes.
