Description:
This window fabrication screw is specially engineered for attaching hardware to frames containing steel or aluminium reinforcement. Its self-drilling point eliminates the need for pilot holes, while the PH metric thread ensures robust grip in reinforced sections. The countersunk facet head allows the screw to sit flush beneath fittings, giving a clean, professional finish. Constructed of martensitic stainless steel and coated in a silver organic layer, it offers strong resistance to corrosion and suits outdoor and damp conditions. Often used with auto-feed machines for “pinning” steel reinforcement inside PVCu profiles, this screw is ideal for window fabricators, glaziers, and installers seeking reliable, efficient fasteners for frame integration.
