### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Nice assortment nylon lock nuts
  

*by G***S on Reviewed in the United States 🇺🇸 on July 15, 2019*

Always have a need and don’t have the lock but size needed which results into a trip to brick and mortar store that may or may not have the item on the shelf. This is a nice well rounded assortment that is reasonably priced compared to buying individual lock nuts. Well made storage case is a plus.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    High quality hardware
  

*by T***R on Reviewed in the United States 🇺🇸 on December 21, 2018*

This is a great assortment of nylon lock nuts in American sizes, and has already come in very handy three times in just two weeks. The nuts are quality pieces and have a very good finish. Having the organizer is a big plus too. This is a very good value, compared to buying individual pieces, especially if you just want to be prepared for the unexpected mechanical fix-it projects that pop up.
