Cummins®

The 4900295 Regular Hexagon Nut is a component manufactured by Cummins, a well-established name in the automotive and heavy-duty truck industry. This nut is significant in the context of heavy-duty truck components due to its role in ensuring secure fastenings, which are vital for the safe and efficient operation of trucks.

Basic Concepts of Regular Hexagon Nuts

A regular hexagon nut is a type of fastener characterized by its six-sided shape. This design allows for efficient use of wrenches and socket tools, providing a firm grip that facilitates easy tightening and loosening. The hexagonal shape is advantageous over other nut shapes because it minimizes the risk of the tool slipping off the nut during use, which can lead to rounding of the nut and compromised fastening integrity ¹.
