This is a nice well rounded assortment that is reasonably priced compared to buying individual lock nuts. Well made storage case is a plus. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Looks good *by A***I on Reviewed in the United States πŸ‡ΊπŸ‡Έ on May 7, 2021* time will tell as to the quality of the nuts, as I have occasion to use them. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars High quality hardware *by T***R on Reviewed in the United States πŸ‡ΊπŸ‡Έ on December 21, 2018* This is a great assortment of nylon lock nuts in American sizes, and has already come in very handy three times in just two weeks. The nuts are quality pieces and have a very good finish. Having the organizer is a big plus too. This is a very good value, compared to buying individual pieces, especially if you just want to be prepared for the unexpected mechanical fix-it projects that pop up. --- ## 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.co.uk/products/145940198-swordfish-30330-210pcs-nylon-insert-lock-nut-assortment-12-sizes](https://www.desertcart.co.uk/products/145940198-swordfish-30330-210pcs-nylon-insert-lock-nut-assortment-12-sizes) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-14*
