## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Very small but well made
  

*by B***S on Reviewed in the United States on 26 August 2023*

They seem well made but I don’t see the short handles giving the leverage needed to open most hydraulic cylinders and any type of “cheater” I am sure would result in a broken pin. I will keep them but I think most cylinders will still have to be broken loose with a large pipe wrench or chain strap wrench which was the whole purpose I bought these. I am tired of my pipe wrench and chain strap wrench chewing up the caps on my cylinders I rebuild. Will be nice on bearings though.

    Good Spanner Wrench
  

*by B***H on Reviewed in the United States on 23 April 2023*

This is a very well made spanner wrench.  It fits my lathe tools perfectly that have a 1/4" hole.  But the ordering process on Amazon is confusing.  I clicked on 6-piece and at the bottom of the page it shows 6 spanner wrenches of various sizes.  So I thought I was getting 6 wrenches.  But I now see that the heading at the top of the page says 1 3/4" to 3" spanner wrench which is exactly what I needed.  So, I'm satisfied, just confused with their display.

    A necessary tool for exploring space
  

*by P***K on Reviewed in the United States on 12 May 2023*

I've been working on my space ship for over a decade and have finally gotten to the hydraulics. This is just the tool I need to tighten up the actuators on the landing gear and the blast shields.
