No issues with the quality at all. I'm sure some people got unlucky, but it looks like some others ordered the wrong size on accident. Just double-check the diameter of your bar and make sure you selected the right size before checking out. Review: Fit perfect, easy to adjust - I was considering being cheap and getting rubber/plastic ones instead, but I’m so glad I opted for the metal! I have plastic ones that came with a dumbbell set which fits my ez curl bar ok, but they take forever to put on and off which makes changing weights tedious and annoying. These metal ones thread perfectly and spin on and off super quickly and easily! Worth the few extra bucks, and I’m sure they’ll last longer. ## Features - Het Nut made of robustmaterial, strong. - 2Pcs / packing Silver color - Anti-slip hex nut fit all 25mm standard weight lifting barbells or dumbbell bars. - Anti-skid silent gasket can reduce the noise.Good dumbbell bars replacement accessories. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08H8Q763L | | Best Sellers Rank | #24,821 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #28 in Exercise Collars | | Brand | Lamoutor | | Brand Name | Lamoutor | | Color | Silver 2pcs | | Customer Reviews | 4.0 out of 5 stars 552 Reviews | | Handle Diameter | 25 millimeters | | Handle Material | Alloy Steel | | Item Weight | 0.31 Kilograms | | Manufacturer | Lamoutor | | Material | Alloy Steel | | Number of Pieces | 2 | | Other Special Features of the Product | No-Roll Head, Non-Slip | | Special Feature | No-Roll Head, Non-Slip | | Style | Adjustable | | Target Use Body Part | Whole Body | | UPC | 711731030098 | ## Product Details - **Brand:** Lamoutor - **Color:** Silver 2pcs - **Material:** Alloy Steel - **Special Feature:** No Roll Head, Non Slip - **Use for:** Whole Body ## Images ![2Pcs Anti-Slip Hex Nut Collar Screw for Barbell Dumbbell Weight Lifting - Image 1](https://m.media-amazon.com/images/I/61KwoI7FJkL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Fits 1” barbells ?** A: Do not buy these they are awful!! Does not fit anything. Sometimes they are returns that are stripped. When you get a replacement they send you back the same ones. Or one would be missing. Size doesn’t even matter. One would be loose one wouldn’t even go on. **Q: these become loose all the time, how to fix?** A: Personally, I just figured you needed to check them/tighten them every time you picked up the bar, but I suppose that if you bought an extra pair and added a pair to the outside of the set you have, that would slow down if not reduce the amount they loosen? **Q: is the product made of iron?** A: The product is made of metal. I am unable to say if it is iron or some other alloy. ## Customer Reviews ### ⭐⭐⭐⭐⭐ No Problems to Report *by C***E on November 5, 2025* Excellent fit. No issues with the quality at all.

I have plastic ones that came with a dumbbell set which fits my ez curl bar ok, but they take forever to put on and off which makes changing weights tedious and annoying. These metal ones thread perfectly and spin on and off super quickly and easily!

This has been one of the worst purchases that I've bought on Amazon in a very very long time Do yourself a favor if you need to buy these things just pay that little extra money and go to an actual store because these are garbage. ## Frequently Bought Together - Lamoutor 2Pcs Anti-Slip Hex Nut Spin-Lock Collar Screw for Barbell Dumbbell Weight Lifting - Yes4All Pair of Threaded Dumbbell Handles 14/16/18/24 inch, Chrome/Rubber Grip, Fit 1” Plates, Weight Bar Connector - CAP Barbell Standard 1-Inch Grip Weight Plates --- ## 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.hr/products/241368809-2pcs-anti-slip-hex-nut-collar-screw-for-barbell-dumbbell](https://www.desertcart.hr/products/241368809-2pcs-anti-slip-hex-nut-collar-screw-for-barbell-dumbbell) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-19*
