I will buy another set if I need it **Q: What’s the installed thread length of the inserts? Specifically 5/16-18** A: Did not measure the insert length, but most inserts are approx 1/2" long in this size range. It only has to be as long as the diameter of the boat to be full strength. So if it is a 5/16 insert the insert needs to be at least 5/16 long. These are. But the tool is junk, I suggest buying a name brand US. Made tool. **Q: will this work on .9 thread?** A: This kit is for 5mm . **Q: If the thread id of the helicoil is m8x1.25, so what is the od of that helicoil?** A: You purchase the kit you need depending on the thread type you are attempting to repair. ## Frequently Bought Together - BILITOOLS M8x1.25 Thread Repair Kit, HSS Drill Helicoil Repair Kit Metric - 80Pcs M8x1.25 Threaded Inserts Stainless Steel Spiral Helical Thread Insertion Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/552713647-bilitools-m8x1-25-thread-repair-kit-hss-drill-helicoil-repair](https://www.desertcart.jp/products/552713647-bilitools-m8x1-25-thread-repair-kit-hss-drill-helicoil-repair) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-11*
