Review: Good price for masonry screws! - Very nice masonry screws! I was able to fasten some shelves and a water filtration system to my cement basement walls! The included drill bit works very well and makes installation a breeze! Very good quantity for the price as well! Review: Good screws at a good price - Screws hold in brick just fine. The included drill bit also works, but you must use a hammer drill. A standard drill will not get the job done. ## Features - BIT INCLUDED IN EACH BOX-Proper bit equals improved holding values and reduced cost - FLAT PHILLIPS HEAD--Can be driven with Phillips Screw Driver - SELF-TAPPING-Taps threads directly into masonry and requires no other anchor - DIAMOND POINT-Easier to drive the screw to save time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071VTG6KN | | Best Sellers Rank | #29,128 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #30 in Concrete Screws | | Brand | CONFAST | | Color | Blue | | Compatible Groove Diameter | 0.19 Inches | | Customer Reviews | 4.5 out of 5 stars 2,622 Reviews | | Drive System | Phillips | | Exterior Finish | Alloy Steel | | Fastener Size | 1/4" x 2-3/4" | | Fastener Type | self-tapping-taps | | Finish Types | Blue Oxide Coating | | Head Style | Flat Countersunk Phillips | | Head Type | Flat | | Item Diameter | 0.25 Inches | | Item Weight | 1 Pounds | | Manufacturer | CONFAST | | Material | Carbon Steel - Blue Coated | | Material Type | Carbon Steel - Blue Coated | | Metal Type | Carbon Steel | | Number of Pieces | 100 | | Point Style | diamond point-easier | | Screw Head Style | Flat Countersunk Phillips | | Screw Point Style | diamond point-easier | | Set Screw Thread Type | Right Hand | | Size Name | 1/4" x 2-3/4" | | Thread Coverage | Fully Threaded | | Thread Size | 1/4 | | Thread Style | Right Hand | | Thread Type | Un | | UPC | 820274000038 | | Unit Count | 100 Count | ## Images ![CONFAST 1/4" x 2-3/4" Blue Flat Phillips Concrete Screw Anchor with Drill Bit for Anchoring to Masonry, Block or Brick (100 per Box) - Image 1](https://m.media-amazon.com/images/I/61MTadj9rVL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good price for masonry screws! *by D***K on October 29, 2025* Very nice masonry screws! I was able to fasten some shelves and a water filtration system to my cement basement walls! The included drill bit works very well and makes installation a breeze! Very good quantity for the price as well! ### ⭐⭐⭐⭐⭐ Good screws at a good price *by B***. on April 8, 2024* Screws hold in brick just fine. The included drill bit also works, but you must use a hammer drill. A standard drill will not get the job done. ### ⭐⭐⭐⭐ Good screws lousy drill bit *by H***T on July 21, 2023* These screws work fine on real rock but are useless on engineered stone used on most homes nowadays. I fastened screws tight on my flag mount then a few days later the mount and flag are lying on ground. Screws vibrated/pulled out with a powdery residue left in holes and on ground from the fake stone. If you use these on engineered stone then use anchors. So far so good. --- ## 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.hk/products/56634466-confast-1-4-x-2-3-4-blue-flat-phillips](https://www.desertcart.hk/products/56634466-confast-1-4-x-2-3-4-blue-flat-phillips) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-06-27*
