I found That I had a box of hex head machine screws without nuts or washers. I have washers but lack the nuts so these fill the need perfectly. They range from M2 - M10 and will add to my fixing's solutions. I just need to make sure that anyone can solve a fixing problem with ease. This box of assorted nuts will fill the gap by creating full sets. They are the perfect solution and terrific value. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Nice *by M***S on Reviewed in the United Kingdom on 27 January 2024* Prefect for my need ### ⭐⭐⭐ 3.0 out of 5 stars M8 nylocks and M8 normal need different spanner sizes. *by A***E on Reviewed in the United Kingdom on 21 July 2024* looks like some of the sizing is not what would expect. Have used 4 x M8 nylocks and 4 x M8 normals + 1 x M12 nylocks so far, M8 normals would not fit in 13mm socket, ring or open spanner, and were loose in the M14s, but OK in the imperial 17/32nds (for those dinasaurs that still have them). The threads on them were also tighter than normal, but went on when pushed. Desparate to get a couple of jobs done in the next day or so, and cheapest way to get assorted sizes that I needed. --- ## 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.at/products/599488849-310-pcs-nylock-nuts-self-locking-nuts-nylon-insert-lock](https://www.desertcart.at/products/599488849-310-pcs-nylock-nuts-self-locking-nuts-nylon-insert-lock) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-09*
