Review: Secured and stable - I used these to fix my wardrobe (Argos brand) to a bookcase. The bookcase was nice and sturdy, but the wardrobe was leaning to the left and that made all the doors go out of alignment or rub against the top. By using these simple bolts I've stabilised the wardrobe so it stands straight again.
Review: Cupboard Bolts - These were ideal to join my wardrobes and cupboards together to make them more stable and sturdy. As described.

### ⭐⭐⭐⭐⭐ Cupboard Bolts
*by J***O on 8 October 2024*

These were ideal to join my wardrobes and cupboards together to make them more stable and sturdy. As described.

### ⭐⭐⭐⭐ Good fixings
*by A***N on 31 May 2025*

Easy to use, just drill the right sizes of hole into your two shelves or cabinets etc for each of the two pieces, screw them together and you’re done. I fixed 3 wooden pine cube shelves together to make one unit and chose the brass colour so they wouldn’t be too obvious. These fixings were perfect and have held them together tightly. They were a little pricey but I’m pleased with the look and their suitability for the job.
