U-Bolts equipped with double flat washers and nylock (nylon-insert) lock nuts provide a highly reliable, heavy-duty fastening combination designed to resist severe mechanical vibration and prevent loosening.
Why Use This Hardware Combination?
Nylock Nuts for Vibration Resistance: The embedded nylon collar grips the bolt threads tightly. It creates constant friction that stops the nut from backing off under heavy shaking, making it ideal for automotive, marine, and industrial use.
Double Flat Washers: Placing a flat washer under each of the two nuts distributes the clamping force evenly across the mounting plate. This prevents surface scratching, protects the base material, and ensures a more stable load distribution.
No Lock Washer Needed: Because nylock nuts inherently resist vibration, using traditional split-ring or tooth lock washers is unnecessary and generally discouraged by engineers. Flat washers are all you need.
