I am trying not to say, buy the right thread then. **Q: Does the kit come with a case and the tools** A: The ad shouldn't have put kit, as you only get the thread inserts in a bag! No case or tool. If you have some steel rod, bend a 90° angle on one end & you put a slice in the other end with a hacksaw or fine cutting disc, if you have an angle grinder & you could make a tool! Thats what I did! ## Customer Reviews ### ⭐⭐⭐⭐⭐ helicoils set *by W***K on 4 November 2024* Very good ### ⭐⭐⭐⭐⭐ Good value *by D***E on 26 May 2024* Product did exactly what it was supposed to ### ⭐⭐⭐⭐ Arrived on time *by D***I on 9 May 2020* I bought these thread insets because my pedal got loose. The inserts are too small put in my pedal and my pedal is too big for the inserts. Does anybody know which size should I buy for a normal crank or pedal. ## Frequently Bought Together - Thread Repair Insert Kit, 60pcs Stainless Steel Thread Repair Insert Kit M3 M4 M5 M6 M8 M10 M12 Helicoil Type - FreeTec 131 Piece Helicoil Type Thread Repair Kit M5 M6 M8 M10 M12 Thread Repair 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.co.uk/products/80395008-thread-repair-insert-kit-60pcs-stainless-steel-thread-repair-insert](https://www.desertcart.co.uk/products/80395008-thread-repair-insert-kit-60pcs-stainless-steel-thread-repair-insert) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
