I think they're M5 but what is the thread number?** A: My blocks were M5 x 0.8 on the four top mounting holes. Be careful when mounting these as the center-to-center distance is 2 mm difference between the width and length run on the blocks. My M5 holes (4) were not drilled properly and gave the block an angled "run" down the rail. You can't correct this. The only option was to drill the matching holes over size to compensate for the alignment. I ordered an assortment of M5 cap head screws from Amazon in various lengths. This M5 set was very helpful during assembly. **Q: Can the rails be attached to the ceiling? Will it support a downward pulling force on the sliding blocks?** A: I wouldn’t do it. The bearings are only on the top of the bushings **Q: Do you have cad files for the linear guides?** A: Just google the SBR specification. The hole pattern is a perfect rectangle 32mm center-to-center in width (across the rail), and 30mm in length. Screw size is M5, no more than 12mm in length. **Q: how much weight can these carry?** A: These rails are strong and should support at least 40 pounds of downward pressure. The rails are also based on the support underneath. I used these rails as cross spans on my router sled. I used an all-aluminum mount for my 3 1/4HP Makita router and had excellent results. It was sturdy with little if any sagging or deflection in the middle of the travel. ## Frequently Bought Together - GUWANJI 2Pcs SBR16-2000mm Linear Rail Guide + 4Pcs SBR16UU Square Type Slide Bearing Block, 16mm Linear Rail Overall Length 78.7 inch/2000mm for Fully Supported Linear Rail - (Pack of 4) Shaft Collar Set for Linear Rail SBR16, All in One Clamp-on Shaft Collar with M5 Set Screw, Bore 16mm, OD 35mm, Thickness 10mm - M6-1.0 x 20mm Truss Head Machine Screws, Full Thread, 18-8 Stainless Steel, Quantity 25 --- ## 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.tn/products/750898285-2pcs-sbr16-2000mm-linear-rail-guide-4pcs-sbr16uu-square-type](https://www.desertcart.tn/products/750898285-2pcs-sbr16-2000mm-linear-rail-guide-4pcs-sbr16uu-square-type) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-22*
