This guide is for DIY enthusiasts and professionals needing a reliable hinge for lightweight doors or applications where traditional butt hinges are unsuitable. The TIMCO Backflap Hinges offer a simple, face-mounted solution for thin materials, providing secure closure. However, their suitability is limited to clean, dry, and low-humidity environments.

Their main advantage is the ability to be surface-mounted onto the face of a door and frame, making them suitable for materials too thin to accommodate traditional mortised butt hinges.
A self-colour finish means the hinge has its natural steel appearance without any plating or coating. It may require additional protection against rust in certain environments.
They are best suited for clean, dry, and low-humidity indoor environments. They should not be exposed to moisture, rain, or high humidity.
A pair of these hinges requires 12 screws for secure mounting, with a recommended screw diameter of 4.5mm (9 imp. gauge).
No, these hinges are designed for lightweight applications. For heavier doors, consider stronger, more robust hinge types.
The open width of the hinge is 106mm, and the length of each flap is approximately 50mm.
Yes, the self-colour finish can be painted or coated to match your decor or provide additional rust protection.
Ensure screws are not overtightened, causing the hinge to bind. Check for any debris obstructing movement. If the issue persists, a light application of lubricant might help, but ensure it's suitable for the environment.
Verify that the correct number and size of screws (12 screws, 4.5mm diameter recommended) are used and are securely fastened. Ensure the hinge itself is not bent and is mounted perfectly straight.
This indicates exposure to moisture. Clean the affected area with a wire brush and apply a rust inhibitor or protective coating. Relocate the application to a drier environment if possible.
The material may be too soft or the pilot holes too large. Use wood filler to repair the hole and re-drill a smaller pilot hole, or use larger diameter screws if the material can support them.
