Moreover, the brass material's resistance to corrosion ensures that the protective quality of the assembly is maintained over time, even in varying environmental conditions.
Brass cross dowel nuts are also used in some engineered products, particularly where precision, lightweight, and corrosion resistance are critical. They are commonly found in products made of metal, such as those containing aluminum, and in electronic components. In these applications, cross dowel nuts serve to join elements with high tolerance requirements while ensuring the assembly remains resistant to rust and environmental degradation. This makes them suitable for use in aerospace, automotive, and marine applications.
To appreciate the full functionality of brass cross dowel nuts, understanding their specifications and features is paramount. Consider the following key specifications and features of brass cross dowel nuts in various applications.
The primary material used to make cross dowel nuts as prominently showcased on their product pages is brass. This alloy primarily consists of copper and zinc. Sometimes there may be small amounts of other metals. The resultant material has excellent corrosion resistance, ensuring the nuts remain functional in various environments, including moisture and marine settings. Moreover, brass's non-magnetic properties make these nuts ideal for electronic and medical equipment applications.
Cross dowel nuts are cylindrical and typically feature unthreaded slots or grooves perpendicular to the nut's original threaded section. This slot allows a dowel to fit snugly into its cross-section. The internal thread is usually a standard size compatible with commonly-used bolts. Typical nut outer diameter dimensions range from 15 mm to 30 mm, while inner threaded diameters are about 6 mm to 10 mm. The slot length and width also vary, measuring about 7 mm long x 1.5 mm wide, accommodating dowels with diameters ranging from 6 mm to 10 mm.
Brass cross dowel nuts typically bear heavy loads and are thus ideal for many furniture applications. Their bearing capacity is directly related to their size and the materials they are installed in. Larger nuts and those installed in solid wood provide greater carrying capacities. Similarly, heavier loads bearing are required by the application, the heavier-duty brass cross dowel nuts should be chosen.
One of the key advantages of using brass as a material for cross dowel nuts is its corrosion resistance. It makes them ideal for use in outdoor or moisture-prone environments. Additionally, brass does not rust, unlike other metals such as iron or steel. This property ensures long-term functionality, making these nuts a reliable choice for coastal and high-humidity environments.
The installation of brass cross dowel nuts is straightforward. It typically requires a pre-drilled hole in the base material where the nut is to be embedded.
