Hello everyone,
I am currently assembling my IKEA Besta cabinet and have noticed that there are several types of screws and fasteners that look quite similar at first glance. To avoid mistakes that could later affect the stability or function, I would like to know: Which screws absolutely must not be mixed up during the assembly of the IKEA Besta?
I am especially interested in whether there are parts that look very similar but have different lengths or head types, which could make incorrect assembly risky.
Perhaps someone has a detailed overview or knows common errors to avoid when dealing with the mix of screws. Thanks in advance for the help!

Basically, when assembling the IKEA Besta, screws differ significantly in length, head type, and thread, even if they look similar.
- The cylinder bolts with internal hex (often 15–25 mm (0.6–1 inch) long) are meant for connecting side panels and shelves.
- Connecting bolts (usually 30 mm (1.2 inches) or longer) have an external hex head/wrench fitting and are used for cam lock connections.
- Chipboard screws for back panels are usually much shorter and thinner.
I recommend sorting all screws by cross-section and length, as partly suggested in the instructions. This helps avoid accidentally using a screw meant for the side panels on the back panel.
A small mark on the screws with a felt-tip pen can also help if you mix multiple packages.

I definitely don’t want to risk the stability by using or mixing the wrong screws.To ensure stability, you should pay special attention to two groups of screws:
- The long connecting bolts (about 35 mm (1.4 inches)) for joining the cabinet corners: these are thick, have a metric thread, and are inserted using a cam lock. Using the wrong bolt may not hold securely.
- The cylinder screws with an internal hex drive (15–20 mm (0.6–0.8 inches)), often used for shelves and side panels: these have a finer thread and are shorter. Using screws that are too long here can damage the material.
Note: Some screws have nearly identical head sizes, with only the length differing. Never use the short ones for load-bearing parts, and vice versa.
So, a clear sorting before assembly is essential.
Avoid confusing chipboard screws with machine screws, even though they may look similar.
Chipboard screws are designed for thin panels, while machine screws are used for load-bearing connections.
It is best to check the instructions and carefully compare the screws before each step.
