- High quality steel         
                                                          
- ESCO® Ultralok® teeth are #1 in average through-hardness
  
  A collection of 30 teeths designed for use on construction wheel loaders and excavator buckets were randomly-sourced and subjected to Brinell hardness tests of their interior surface, performed by Intertek PSI, an independent laboratory specializing in metallurgical testing and failure analysis.

  Each tooth was cut in half, to reveal the interior surface. Hardness measurements were then conducted  
  by Intertek PSI on various locations across the interior surface.  
  To account for varying degrees of hardness depending on the proximity to the tip and/or exterior surfaces  
  of each tooth system, an average Brinell hardness was calculated using Intertek PSI’s measurements  
  captured along the centerline of each tooth’s interior (the area circled in red). This method captured  
  hardness measurements from each section of the tooth that would be revealed as it wears away after use  
  in the field.

-  ESCO Ultralok teeth ranked #1 in average centerline hardness.[![Picture4](https://blog.essltd.com/hs-fs/hubfs/Picture4.png?width=300&name=Picture4.png)](https://esco-ultralok.weir/)• While other systems logged hardness scores as low as 415 BHN, ESCO Ultralok teeth were the only product to measure over 530 BHN across the entire centerline of every tooth tested.
- ESCO Ultralok teeth had the most consistent hardness across the centerline (= zero variation  
  from the tip of the tooth to the rear box section).

- High-integrity welding techniques
- Triple taper design for faster loading and cleaner dumping
