The 3mm x 35mm Dowel Pin is a small but important mechanical hardware component used for alignment, locating, spacing, positioning, repairs, and repeatable assembly. Dowel pins are commonly used in 3D printers, CNC fixtures, jigs, brackets, mechanical linkages, robotics, shop-built tools, and custom DIY machine projects where parts need to line up accurately.
With a 3mm diameter and 35mm length, this dowel pin is useful for compact assemblies that require a straight locating pin, pivot-style alignment point, replacement hardware, or repeatable positioning between two parts. It can be used in printed parts, machined components, laser-cut plates, drilled brackets, prototype fixtures, and small mechanical systems.
A dowel pin is different from a screw because it is not primarily used to clamp parts together. Instead, it helps align parts accurately so they return to the same position during assembly. This makes the 3mm x 35mm Dowel Pin useful for jigs, fixtures, machine setups, repair work, hinge points, sliding assemblies, and parts that need consistent repeatability.
This dowel pin can be used in 3D printer repairs, DIY printer builds, CNC fixtures, routing jigs, shop tools, robotics mechanisms, electronics mounts, small hinges, alignment blocks, and mechanical prototypes. Builders often use dowel pins where a smooth round shaft or locating pin is needed instead of a threaded fastener.
The 3mm size is practical for smaller hardware assemblies and compact mechanical builds. It can be used with 3D printed parts, drilled holes, machined plates, brackets, and laser-cut or CNC-cut components. For best results, always confirm the hole size, fit type, and material before installation. A hole that is too tight may damage the part or make the pin difficult to remove, while a loose hole may reduce alignment accuracy.
For related assembly hardware, browse the Fasteners category. You may also want to pair dowel pins with Metric Socket Head Screws, Hammerhead T-Slot Nuts, or related 3D printer and machine-building components in the 3D Printer Parts category.
Dowel pins are commonly used as precision locating elements in mechanical assemblies where repeatable alignment matters. For general engineering context on dowel pin applications and fit types, see this dowel pin technical reference.

Before installing the 3mm x 35mm Dowel Pin, confirm that the hole diameter matches your intended fit. A slip fit allows the pin to be inserted and removed by hand, while a press fit is tighter and may be intended for permanent or semi-permanent installation.
Do not hammer or force the pin into a hole that is too small unless your application is specifically designed for a press fit. Excessive force can crack printed parts, deform softer materials, damage brackets, or make the pin difficult to remove.
Dowel pins work best when the mating holes are straight and properly aligned. If the holes are misaligned, the pin may bind, bend, or prevent the assembly from seating correctly. Check alignment before final installation, especially when working with jigs, fixtures, brackets, or multiple locating pins.
If the pin is being installed into a drilled, machined, laser-cut, or CNC-cut part, remove burrs before assembly. Burrs can interfere with fitment, scratch the pin, or prevent accurate alignment between parts.
Keep the pin clean and free from dirt, rust, chips, adhesive, and abrasive debris. If the pin is used as a sliding or pivot point, inspect it regularly for wear and apply a suitable light lubricant if needed for your application.
When using dowel pins with 3D printed parts, print tolerances matter. Holes may need to be adjusted, drilled, reamed, or lightly cleaned depending on printer calibration, material shrinkage, and desired fit. Start with a test fit before forcing the pin into a finished part.
