Knurled Thumb Nuts in Brass
Decorative Circular Nuts Installed by Hand
A knurled thumb nut is a nut with a knurled outside surface, rather than hex. This makes it easy to tighten by hand, as well as adding a decorative finish. Knurled thumb nuts are used mostly on finished products, such as light fixtures, antique cars, and motorcycles.
Brass
Brass is an alloy made of copper and zinc. The color of brass can vary from dark to light based on the zinc content; more zinc content produces lighter brass. Brass is prized for its appearance and is often used decoratively. However, it is quite soft, so it is not suitable for all applications. Brass conducts electricity and is also a good conductor of heat.
