What Screwdriver to Fix My Dyson?

“Which screwdriver do I need to fix my Dyson Vacuum cleaner?”

This is something we are asked every week, so I thought I would write an article to clarify it.

Not every Dyson model of vac use the same size in all applications. But I will make it simple it for you below.

Dyson vacuum cleaners are assembled using what are called Torx screws. Have a look around your Dyson vacuum cleaner and you will see them. The domed  head is shaped rather like a star and they look like this.

Some have a pin in the middle like the one above that is called an anti-tamper screw; some older ones do not.

What is a “torx”?

Torx (pronounced “torks”), was first developed in 1967 by Camcar Textron, and is the trademark for this type of screw head characterized by a 6-point star-shaped pattern.

A popular generic name for the drive is “star”, as in “star screwdriver” or “star bits”. The official generic name, technically called ISO 10664, is hexalobular internal. This is sometimes abbreviated in tool databases and catalogues as “6lobe”.

Torx screws are commonly found on cars, motorbikes, bicycle brakes, computer hard disk drives, computer systems and consumer electronics. And of course Dysons. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available.

However, as Torx drivers became more common, tamper-resistant variants, as described here, were developed.

A screwdriver with that “anti-tamper” feature will fit both types of Torx screw, one without that facility will not. So you need one with the anti-tamper tip to be certain, as that started to be used in some applications from the DC07 and DC14 through to the current models like the DC39, DC40, DC41 and Big Ball Cinetic.

The most typical size used on Dyson vacs is the T15. The T10 and T8 can be found on some later model machines as well. For example, the T10 is used on DC24 soleplates.

When you are buying a T15 Torx screwdriver, the length of the blade is a factor that many people don’t think about. They are all the same right? No.

Most T15 screwdrivers have as standard 3″ long blade.

Dyson vacs have some deep sunk screws on the housings that you need a four inch blade to get to.

You don’t want a screwdriver shaft wider than about 4-5mm either, so those big fat “do everything” screwdrivers that have slot-in magnetic tips are of no use on a Dyson. You need one that looks like this.

Dyson Star Screwdriver

Not very many firms make the ones with a four inch blade that doesnt have the silly t-shape handle. I prefer a traditional shaped screwdriver. You probably do too.

Silverline make one, but I have never been a big fan of the quality of Silverline tools personally, so I tend to avoid that brand despite it being cheap.

Snap On (and we assume Bluepoint and Mac too) do one with a six inch blade (longer than you need but OK), the part number is SGDTRX615BR, but it is a special order and costs $26 in the USA. I am not sure if it is available in Europe.

Draper make them. Draper quality is typically alright, but not especially cheap often times. But the five quid or so that they cost doesn’t seem too bad.

Smiths Tools also make them, they are pretty good, and not awfully expensive either.

You ONLY need a T15 for these models DC01, DC02, DC03, DC04, DC05, DC07, DC08, DC14, DC19 and DC25.

If you are going to be working on models such as the the DC24 and other later Ball machines like the DC15 and DC18, and newer machines like the DC39, DC40 and DC41, not to mention new Cinetic machines, you will also need a T10 with an anti-tamper end and also a T8 for some jobs.

If you are planning to repair later models, get a T8, T10 T and the T15 T (The extra “T” denotes anti-tamper).
