## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    E-Z Lok stands by their excellent product
  

*by A***S on Reviewed in the United States on August 8, 2021*

I ordered the M14-1.5 (1.5D/21mm length) economy kit, but similar to another reviewer, received a kit which contained a different size set. Mine was labeled as ordered, but contained the parts for a 1/2-20 (1D/14mm) kit, which I determined by both tap imprint and comparison both to the bolt to be installed and a thread pitch image from the Bolt Depot fastener tools PDF (make sure to print at 100% scale). Note that you have to stretch the coils to match the pitch image if you want to measure: they do not arrive expanded to length at rated pitch.In the attached image, the left kit is the first received, the right kit is the replacement. Clearly different contents.Since I needed this item for a repair this week and it was out of stock at Amazon, I reached out to E-Z Lok directly to see if they could help. They responded within a few hours and shipped me a replacement kit with the correct items the same day via Next Day Air. They even included a Certificate of Conformance (asserting that the shipped item matched the ordered item).I'm delighted that E-Z Lok stood by their product, and my oil pan is now back in business with a solid thread repair after the drain bolt hole had been stripped during previous ownership: an aftermarket Dorman toggle bolt plug had been there when I bought this vehicle used, and it was starting to leak). This is my second bolt hole repair with E-Z Coil. It's a well-designed product, and with this kind of customer service, I'm a customer for life.

    Works as it should

Easy to use just like all helicoil thread repair systems.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Easy to use correctly
  

*by J***O on Reviewed in the United States on January 6, 2024*

The thread-tapping tool fit readily in the thread-tapping handle I already owned (the kit doesn't include that component) and the blue-handled tool made it easy to correctly install the helical insert. And the repair to the housing of my high-speed router is holding well.The final test is how well the helical insert stays in place. But if it doesn't stay put, one can use a thread-locking compound between the insert and housing.
