They were a bit expensive but they worked great. Screwed down patio rail through tile. Put them in with silicone to stop water penetration. Expect they will last for years. ### ⭐⭐⭐⭐ Quality but... *by J***0 on July 15, 2022* They certainly feel sought stout compared to other 1/4 inch screws but there were only 24 in the box, at this price point I would expect to get the full 25. ### ⭐⭐⭐⭐⭐ As advertised *by B***S on October 30, 2020* Great product --- ## 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/63108917-simpson-strong-tie-sds25300ss-r25-strong-drive-sds-heavy-duty](https://www.desertcart.tn/products/63108917-simpson-strong-tie-sds25300ss-r25-strong-drive-sds-heavy-duty) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-21*
