Save Huge Installation Time with EC Fastener Concrete Frame Screws
Traditional expansion anchors waste installers’ time on repeated drilling, frame repositioning and concrete edge spalling during window and door fitting. Our self-tapping concrete frame screw solves all these pain points perfectly for timber, uPVC and metal frames fixed onto concrete, brick and block substrates.
Core Advantages for Construction Contractors
One-step direct threading, no plastic plugs needed Only drill a 6mm pilot hole through the frame and drive the screw directly. No outward expansion force prevents concrete cracking near edges, eliminating frame removal and secondary fixing work, greatly boosting efficiency for high-volume construction projects.
High-low thread design for strong holding power Unique high-low thread profile delivers powerful pull-out resistance while clearing drilling debris smoothly, lowering driving torque and screw jamming risk. Full-length threads lock frames firmly to masonry and avoid loosening caused by vibration or seasonal temperature changes.
T30 Torx trim countersunk head for tidy finishing The Torx T30 drive reduces cam-out and driver wear, while the flush countersunk head creates a clean exposed finish. Anti-vibration locking ribs under the head enhance long-term fastening stability for finished window and door projects.
Heavy-duty material & multiple corrosion finishes Made of hardened 1022 carbon steel with tensile strength over 1000MPa. Standard yellow zinc plating meets RoHS for indoor use; stainless steel, Dacromet and hot-dip galvanized coatings are available for coastal, high-humidity outdoor environments.
