Window Fabrication Screws

Typically, all window screws come with a Phillips No2 drive, which is useful in a manufacturing environment as there is no requirement for tooling to be changed regardless of the type of screw used. Window fabrication screws are normally categorised for use with reinforced frames or non-reinforced frames, as this determines the screw point and thread type. Reinforced frames require a self drilling tip to penetrate the aluminium or steel reinforcing section within the frame, whereas a sharp point is sufficient for non-reinforced frames.

Coarse or Hi-Low threads are suitable for plastic only construction and self-tapping threads offer secure fastening in reinforced frames. Window fabrication screws can, by the nature of where they are used, be susceptible to corrosion from environmental conditions, so careful consideration must be given to the specification of each screw before use. Window fabrication screws are manufactured from three main material types – zinc plated carbon steel, martensitic stainless steel and austenitic stainless steel; corrosion resistance is determined by salt spray test indicating the number of hours corrosion protection.
