A Cushion Hitch Nut has a six-sided design and adds a strategically placed slot running through its body. This slot allows for the insertion of a cotter pin or retaining pin, effectively locking the nut onto the bolt and preventing it from loosening even under extreme vibrations, shock loads, or temperature changes. This combination of the inherent strength of the Hex shape and the extra security of the pin makes the slotted Hex nut a reliable choice for specific applications.Attributes:• Made of Steel which has excellent strength• Manufactured to precise specifications and is built for durability and reliabilityApplications:A Cushion Hitch Nut is used to securely fasten components together using a threaded bolt or screw, providing exceptional resistance to loosening under vibrations, shock loads, and temperature changes, all while allowing for the use of a cotter pin for added security.
