### ⭐⭐⭐⭐ 







  
  
    Poor thread
  

*by A***H on Reviewed in the United Kingdom on 31 March 2023*

Be careful what you use to tighten the nuts up with  this length seems ok but the ones which are 10mm longer it is very easy to strip the thread. They are also made of a soft metal.

### ⭐⭐ 







  
  
    Misleading
  

*by D***N on Reviewed in the United Kingdom on 24 April 2023*

Photo suggests half have full length thread and half have a short thread, ALL are short thread.
