TIMCO Uncranked Butt Hinges - 75 x 48

Each pair of TIMCO Uncranked Butt Hinges (75 x 48mm) can support a maximum door weight of 20kg.

No, these hinges have a self-colour finish and are only rated for Corrosion Class 1 (clean, dry & low humidity environments), making them unsuitable for external use or high-moisture internal areas.

The recommended screw size is 4.0mm diameter, which corresponds to an 8-gauge screw. You will need 12 screws per pair of hinges.

These hinges have a fixed pin, meaning the pin is not designed for easy removal. To detach the door, you would need to unscrew the hinges from either the door or the frame.

The hinge is 75mm in length and 48mm in width (open width). The material thickness is 1.5mm.

Clean the hinges using a dry or slightly damp cloth. Avoid abrasive cleaners or solvents, especially on the self-colour finish.

An 'uncranked' hinge, also known as a 'flat' or 'butt' hinge, has straight, flat hinge leaves. This contrasts with 'cranked' hinges which have offset leaves, often used for doors that need to sit flush or have specific clearance requirements.

Apply a small amount of appropriate lubricant (e.g., white lithium grease or silicone spray) to the hinge pin. Ensure excess lubricant is wiped away.

Check if the hinges are correctly aligned and fully seated. Ensure screws are tightened securely. Minor adjustments may be needed by slightly loosening screws, repositioning, and retightening.

This is common with self-colour finishes in humid conditions. Clean the surface gently with a dry cloth. For functional use, continue with the product. For aesthetic improvements, consider painting the hinge with a suitable metal paint after cleaning and drying.

Ensure all 12 screws are securely tightened into the door and frame. If screw holes are stripped, they may need to be filled and re-drilled, or larger screws used with caution.
