Easy to install. ### ⭐⭐⭐⭐ Review *by L***N on 10 October 2025* Just know that these are very lightweight. I thought they would be a lot more solid and have more strength, but they are light. I have a feeling that overtime. The threads will wear because the material seems pretty “soft” for metal. Very light aluminum feel. Idk, they are fine, and I measured them precisely to go on an exact size stainless steel rod and I had to file the inside of them down lightly. I checked the measurements multiple times, yet I still needed to open them up a bit to get the rod to move through. I tried using a little oil first before I filed them, but it wasn’t enough. So maybe consider the measurements as being a possible bump in the road. It was no big deal to file them out, but I would’ve preferred not to. I’m using them to lock the rails going in one direction on a router sled. Also, I will mention that I was not a fan of the angle of the screw going into the side. It was a really messed up angle and I’m not sure if I’m using the product wrong or it wasn’t meant to be used for what I’m using it for but this direction of that screw complicated things. --- ## 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.za/products/557570101-pack-of-4-shaft-collar-set-for-linear-rail-sbr16](https://www.desertcart.co.za/products/557570101-pack-of-4-shaft-collar-set-for-linear-rail-sbr16) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-18*
