Aplicación

Thumb nuts are for applications where something only has to be fastened temporarily or needs to be frequently adjusted, changed, or removed. Since you only need your hands to drive these nuts, they are also useful for situations where you need to fasten something quickly.

Knurled nuts are commonly used in any application where the fasteners will be removed regularly but are not needed for structural support. They can commonly be found on electrical panel covers, precision measuring tools, squares, and service covers. The advantages of using a knurled fastener in this situation are: it improves the ease of removal, deters the possibly over-tightening/stripping, and does not require any tools to manipulate the fastener. However, there are knurled nuts available that have a slot cut into them for the use of a Phillips head screwdriver. This expands the versatility of the nut and provides the option to use tools. Nuts with the Phillips slot are common in applications where vibration is a concern.

Brass Thumb Nuts Vs Stainless steel

18-8 or 304 grades of Stainless steel are suitable for numerous general objective applications, specifically freshwater and also non-salt water damp environments. Corrosion-resistant and resilient, 18-8 stainless steel is equivalent to the A2 grade of stainless steel. Stainless steel is good for general purpose applications, especially those involving water or freshwater. Suppose you need stainless steel for more corrosive environments, such as marine or saltwater applications. In that case, we recommend the 316 grade of stainless steel.


Brass is an alloy constructed from copper as well as zinc. The shade of brass can vary from dark to light based on the zinc material; even more zinc material creates lighter brass. Brass is prized for its look and is frequently used decoratively. Nevertheless, it is quite soft, so it is not appropriate for all applications. Brass carries out electricity and also is additionally an excellent conductor of heat. Brass is stronger and harder than copper, but not as strong or hard as steel. It has great formability and is resistant to saltwater corrosion.
