2 Way Lock Nuts

2 Way Reversible Lock Nuts for industrial vibration resistance

About 2 Way Lock Nuts

2 Way Lock Nuts, also referred to as 2 way reversible lock nuts are special purpose fastening components that provide secure and reliable locking service in high vibration and high load applications. These nuts are designed with a special two-way locking system to fix the clamping in either clockwise or counterclockwise similar to that of locking in a lap nut, so the same clamp level is guaranteed and it cannot be loosened by movement, shock or cyclic stress. 

2 Way Lock Nuts are made with very controlled processes of forging and threading which gives the nut high durability, thread accuracy, and service life. Their good structural design ensures that they are able to withstand high mechanical loads and optional surface treatments and material options offer improved corrosion conditions to allow them to be used in harsh or outdoor environments. Because of its versatility, and reliable locking behavior, 2 Way Lock Nuts are commonly used in the automotive assemblies, industrial machinery, structural installations and equipment where safety, reliability, and lessening of maintenance is of the essence.
