Expanding pins are becoming more popular because they are easier and quicker to fit, however it is worth noting a few things about expanding pins, because without taking a reasonable amount of care they will not work, and you will damage your furniture to the point you cannot build it.

You will find these on BandQ’s Darwin Range, the Holstead Wardrobe from Argos and most of the Next-to-no-time furniture from Next.

The principle of how they work is quite simple, simply push the pin into the hole (instead of screwing it in), and when the minifix cam is turned, it pulls the pin up a little and the base of the pin expands, tightly gripping the hole.

In order for the expanding pin to function properly, the collar must be flush against the panel into which it is inserted, and the two panels must be pushed firmly together whilst the minifix cam is turned to tighten the joint.

So there are two points of failure, if the pin is not fully inserted, then it will not grip the hole properly, damaging the edge slightly. On re-seating the pin correctly in the hole, it will no longer grip the hole with the same strength as the edge is slightly damaged. The damage can be less than a millimetre, yet it is sufficient to render the joint to fail. Similarly if the panels are not flush with each other before the minifix cam is tightened, it can draw the pin out of the hole, repeating the problem above.

Whilst both of these issues are very easy to avoid, it is worth pointing out, that it can be very difficult on wardrobes due to their weight, and on small items such as nests of tables to avoid.

Personally, I do not think these fittings are fit for purpose at all.

Certainly the ones on the Argos Holstead wardrobe is simply not strong enough, and expect over time a lot of these wardrobes will come apart during use from the constant banging of the sliding doors. When I have been building them, I have reinforced the joints with discrete brackets.

I have lost count of the number of Next wardrobes with the Next to no time fittings which customers have failed to build themselves and have called us in to fix them. Next seem rather disinterested in helping their customers when this happens, often telling the customers it is their own fault.

So if you do come across them, please ensure you:

a) fully insert the pins

b) ensure the two panels are firmly pressed together and there are no gaps before you tighten the minifix cams.
