Started to play with circles instead, how the screws and bolts can work around a circle.

Ive separated the poster into 4 parts, bolts and screws, non tappered and tappered. Simple info graphics. Ive divided the bolts from screws using the colour cyan, which is a cold colour and in this case i think works with the cool screws and bolts topic.

However on the whole this poster is blinking boring. Its very simple and i arent very happy with it.
