Window Concrete Screw
Window Concrete Screws are purpose-designed fasteners used for fixing uPVC, aluminum, or wooden window frames directly into concrete, brick, or masonry. They are manufactured to ASTM, DIN, ISO, and ETA standards using hardened carbon steel or stainless steel. Their deep-thread design ensures strong anchoring without the need for plugs or inserts. Available in countersunk, pan, or hex head types, they allow neat, secure, and vibration-resistant installations. They are widely used in construction, glazing, interior fit-outs, and renovation works for reliable window frame fastening.
