I believe it's because they tend to lose their tight fit as the nylon wears. This means that I buy a lot more of these than the usual nuts. What I use them for is securing casters on cabinets for the shop because they can wiggle loose over time. These create a tight fit, and came in a little reusable plastic container. I am not familiar with this brand, but they work fine, and would buy them again. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars 1/4-20 Stainless Steel Nylon Lock Nuts - just as advertised! *by J***E on Reviewed in the United States on May 3, 2024* I ordered the size 1/4-20, and I can confirm that is the size I received. The quality seems decent on these, and they are indeed stainless steel construction. The nylon insert works as intended to "lock" the nut and help prevent these from vibrating loose. The case isn't much, but it is flexible, transparent, and adequate for holding this quantity of nuts. Overall I'm happy with these and I wouldn't hesitate to order this brand again! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars 1\4-20 Nuts with lock Nuts *by H***M on Reviewed in the United States on May 4, 2024* I love this pack had more than I needed for the project I always seem to need this size nuts for something. A 50 piece pack is almost the perfect size. The Nylon insert locks the nuts perfectly and being a 7\16 size means almost everyone has the right size wrench or socket to tighten them. I really like they are stainless steel instead of painted. --- ## 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.fi/products/624184574-50pcs-1-4-20-nylon-insert-hex-lock-nuts-304](https://www.desertcart.fi/products/624184574-50pcs-1-4-20-nylon-insert-hex-lock-nuts-304) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-05-16*
