🔩 E-Z Lok SK20715 Helical Threaded Insert Kit: 304 Stainless Steel, #12-24 Thread Size, 0.324" Installed Length (Pack of 10) – Secure and Durable Fasteners for Various Projects Review

Hole prep was very easy (aluminum). Installing the paste was a bit tricky, but once I realized there was a bug in my process, the final install was very clean and reliable. I would buy this brand again anytime.

This kit worked perfectly to rebuild my Holley carburetor. After the price of the Holley kit (which is basically the same as this kit except that the Holley kit is way overpriced) I decided to take a chance. This set had everything I needed and more. If you ripped the bolt hole on your Holley carburetor, save your money and buy this kit instead of buying Holley's overpriced ones.

I bought this for my Holley carburetor that had two threads loosening from the rear shell. This was my first time using something like this and it was easy. I recommend this to everyone. It cost $80 plus dollars from other competitors. This company had less than half that amount. Use this brand, you will not regret it
