Knurled Nuts, also known as thumb nuts, are easily distinguishable due to their knurled outer surface. These nuts can be tightened by hand or secured within a substrate. These nuts can be easily turned by gripping the knurled edge between a forefinger and a thumb. Generally, knurled nuts are used in lightweight applications, where tight fastening is not required.
