Unreinforced window friction stay screws are specialist fasteners designed for securely fixing friction stays into non reinforced uPVC window profiles. Engineered for reliable grip without steel inserts, they ensure smooth sash operation and consistent performance in lighter duty applications.
Available in a range of sizes and typically finished in zinc plated (BZP) or A2 stainless steel, these screws provide dependable corrosion resistance, easy installation, and secure fixing for domestic window systems where reinforcement is not present.
