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 ### ⭐⭐⭐⭐⭐ Great Value *by D***Y on June 30, 2025* Great product and an amazing value vs what is sold at the big box home improvement stores. ### ⭐⭐⭐⭐⭐ Great value, just as strong as name brand. *by R***A on August 16, 2024* We use about 50 a week and maybe I've broken the head off of 3 of them in the past 4 months. Honestly, that's most likely only because my guy was using too much tork with my impact driver. Going full throttle while the thing is already set. Yea, they might break then. If you know how to use a drill. You shouldn't have an issue. These are good screws. Much better than buying 15 for the same damn price at my local hardware store. ### ⭐⭐⭐⭐ Worked fine *by O***G on October 16, 2024* I used a few of these screws into block. I read previous user reviews that expressed concerns with the quality of the screws and the drill bit. I took it easy drilling the holes and had no problems. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/137380850-3-16-x-1-3-4-hex-head-concrete-screw](https://www.desertcart.jp/products/137380850-3-16-x-1-3-4-hex-head-concrete-screw) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-16*
