The lag bolts I got at the hardware store were even worse. These bolts solve those problems by giving me tons of peace of mind knowing I won't find broken bolts later. And as I already said, not having to drill pilot holes is awesome. ### ⭐⭐⭐⭐⭐ Great screws *by P***N on July 12, 2018* Great screw. Really strong and don't break ### ⭐⭐⭐⭐⭐ Five Stars *by L***R on July 23, 2018* love these new screws --- ## 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.sn/products/59559671-15-x-3-construction-lag-screw-exterior-coated-torx-star](https://www.desertcart.sn/products/59559671-15-x-3-construction-lag-screw-exterior-coated-torx-star) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
