The hole has to be smaller to allow the masonary screw to hold . Good luck **Q: made in usa?** A: Website listed on the box ( Concrete Fastening Systems, Inc.) sells the product from Cleveland, OH, USA... but can't find a 'Manufactured in... ' label. Works well though. Similar to Tapcon, but less expensive. **Q: This has a shear rating of 540 what ? the same as the 3/16” fastner ? i don’t believe they can be the same. please explain it to me. thanks** A: lbs per square inch. metal could be the same strength even if its thicker ## Customer Reviews ### ⭐⭐⭐⭐ It works *by D***G on 2 February 2024* ### ⭐⭐⭐⭐⭐ Best with hammer drill but worked perfectly. *by R***K on 7 February 2024* ### ⭐⭐⭐⭐⭐ Just like brand name brand *by A***R on 17 July 2023* --- ## 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.uk/products/402451235-confast-3-16-x-2-1-4-hex-head-concrete](https://www.desertcart.co.uk/products/402451235-confast-3-16-x-2-1-4-hex-head-concrete) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
