DESCRIPTION
A locknut, also known as a prevailing torque nut or stiff nut, is a type of fastener that resists loosening under vibrations and torque. The 3771005 locknut is commonly used in trucks to secure critical components such as wheels, bearings, and suspension systems. It features a specialized design that creates friction between the threads of the bolt and the nut, which prevents it from rotating freely. This type of locknut requires higher torque values to install compared to standard nuts but offers excellent resistance to self-loosening over time. The 3771005 locknut is made from high-strength steel and can withstand extreme loads and harsh environmental conditions.
