Of the package of 20 brackets, 10 had two properly tapped holes, 8 had holes tapped that had retained chips or burrs that requires chasing with a tap before the fastener could be threaded-in, and two were each missing threads altogether on one hole. While none of this warranted retiring the product for a refund, the needed rework was a waste of time and would have been even more problematic if I hadn't already owned metric taps. ### ⭐⭐⭐⭐⭐ Essential for assembly *by G***3 on Reviewed in the United States on March 6, 2021* A must-have for building corners with t-slot and v-slot. These are smooth, nicely coated, and don't (yet) bend. I was annoyed that the set screws weren't already installed, until I realized there are different orientations that require set screws installed in different directions. Play around and you can make inside, outside, even sliding connections. ### ⭐ Doesn't fit 2020 extrusions without grinding *by M***L on Reviewed in the United States on July 18, 2019* Used on Tevo Nereus. Did not fit without modification. --- ## 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/136490597-boeray-10pcs-black-t-slot-l-shape-interior-inside-corner](https://www.desertcart.hr/products/136490597-boeray-10pcs-black-t-slot-l-shape-interior-inside-corner) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-24*
