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. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works as it should *by B***L on Reviewed in the United States on May 15, 2024* 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. ## Frequently Bought Together - E-Z Lok EK50920 Metric Helical Threaded Insert Kit, 304 Stainless Steel, M10-1.25 Thread Size, 20 mm Installed Length (Pack of 10), Black - Loctite Threadlocker Red 271 locks, seals threaded fasteners permanently, prevent loosening from vibration, great for engines, machinery, vehicles for valve covers, water pumps, and alternators, 6ml --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/36243598-e-z-lokek50920-metric-helical-threaded-insert-kit-304-stainless](https://www.desertcart.dk/products/36243598-e-z-lokek50920-metric-helical-threaded-insert-kit-304-stainless) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-25*
