Lately I've been seeing colour coded screw bits, like in the set below (from Lidl's store brand, Powerfix).

A bit set with colour coded bits
(Click for larger version)

  • Red for Phillips head
  • Blue for Pozidriv
  • Orange for slotted
  • Yellow for Torx
  • Pink for hex

Is this colour code universal? Or do other brands / manufacturers use different codes?

  • I've added the comment to my answer, please let me know if that's ok now. – abdnChap Jan 30 '20 at 9:50
  • @abdnChap yes it is. – SQB Jan 30 '20 at 9:53
  • Thanks, I was thinking maybe I should have put them in a table... – abdnChap Jan 30 '20 at 10:04
  • There's a big-box store brand here in the States that uses blue for metric sockets and red for SAE. Or is that the other way 'round... :/ – FreeMan Jan 30 '20 at 14:17

The colour codes are NOT universal. There is no agreed upon universal colour code for colouring bits (to my knowledge).

I have found that each brand (mostly) follows their own colour coding. Powerfix uses the colours you describe, and some brands, either intentionally or otherwise, use the same colours as other brands.

But mostly, they do not. For example, Halfords uses

  • Blue: Philips
  • Yellow: Pozidriv
  • Red: Flat
  • Green: Torx

While Wera uses

  • Red: Phillips
  • Black: Pozidriv
  • Green: Torx
  • Blue: hex
  • Yellow: flat

And then if all the tools in a set are the same, e.g. hex keys, Wera uses colours for the sizes instead.


On my set, they all have a yellow band - to help find them when you drop them I suppose, and that is for phillips. torx ie all...

My set was made by DeWalt, so not (probably) a cheap chinesium brand... I have also seen others where all the bits have a red band...

    DeWalt do seem to have something of a yellow colour theme, so the visibility of the bits may not have been uppermost in the designer's mind. – Andrew Morton Jan 29 '20 at 14:02
  • @AndrewMorton the bits are mostly black :) – Solar Mike Jan 29 '20 at 14:03
