Screws & Fasteners
Your windows and doors may contain lots of screws, rivets and specialty fasteners to keep components, such as locks and hinges, properly fitted.
Fasteners need to be:
- Strong enough for the job that they have to do. Depending on the fixing requirements, fasteners generally work by clamping items together and by resisting sheer (sideways) loads.
- Correctly sized, including the right length, diameter and thread design.
- Compatible with all the materials that they come into contact with.
- Properly fitted, including preparation for positioning the fastening, and correctly tensioned.
- Non-corrosive so as not to cause failure or detract from the good looks.
- Well made without rough edges - if you can see them they need to be smooth, look good, and, if coloured, matched to the surrounds.
- Industry standard sizes so you can get an exact replacement if needed.
- If they are manufactured to WANZ Standards, they will carry the WANZ Component Supplier Mark and be guaranteed by the component supplier.
