The 1/4" Hole, 1" Length 10-12 Screw Expanding Plastic Green Screw Anchors are designed for fastening applications in various building materials. These anchors are suitable for use in concrete, tile, or marble surfaces. Constructed from plastic, they are unaffected by moisture, which helps maintain a firm grip. The anchors are color-coded green for size identification and are compatible with screw sizes No.10 to No.12. They provide a pull-out strength of 250 PSI when used in 4000-PSI concrete. These anchors are intended for the installation of shower door hinges, clamps, and extrusions. The expanding design allows for a firm hold within the substrate, making them suitable for various hardware mounting tasks. Each anchor is 1" in length and requires a 1/4" drill hole for proper installation. The plastic construction is resistant to environmental factors, ensuring the anchors remain effective over time. These anchors are supplied in a minimum order quantity of 100 units, supporting large-scale installation projects. The green color coding simplifies the selection process for installers, ensuring the correct anchor size is used for the specific screw diameter. These fasteners are a standard component for mounting hardware to masonry or tiled surfaces.
