Window Fabrication Screws

Buy Window Fabrication Screws

Window fabrication screws do one job - hold your frames together precisely and permanently. Whether you're manufacturing uPVC windows, aluminium frames, or composite profiles, the right screw matters more than most people expect. Wrong thread pitch or material can strip a frame, cause corrosion, or fail an installation entirely.

This category covers everything you need for production-line fabrication and one-off installations alike.

What Window Fabrication Screws Are Used For

These screws are designed for joining window frame corners, fixing reinforcement steel inside uPVC profiles, securing glazing beads, and attaching hardware like hinges and handles. They're not general-purpose fasteners. The geometry, thread type, and drive style are all calibrated for the thin-wall sections and softer materials found in window profiles.

Common applications include:

​

- Corner joint assembly on uPVC frames and sashes
- Steel liner fixing within hollow uPVC extrusions
- Aluminium-to-aluminium frame connections
- Hardware mounting on fabricated window units
- Glazing bead and weather seal retention
