A knurled screw or nut has an etched, cross-hatched, or diamond patterned finish instead of hexagonal or square edges to help in tightening or loosening the nut without the use of a tool. The knurled surfaces provide enough grip to hold the nut between the thumb and forefinger. Hence it is also called a thumb nut. It is mainly used on small-diameter bolts within electrical components.
