PennEngineering® Datasheets for Nuts

Nuts are a type of hardware fastener with a tapped inner diameter. They are used with a mating threaded bolt or rod to secure components. There are many sizes and varieties of nuts; each with a particular fastening purpose. Some nuts can be applied without tools, and others may have special designs to prevent the nut from loosening.
