'Nuts & Bolts' metal construction sets had identical parts to Eitech Construction. It was manufactured in the China by Polylong. Most were imported to the UK by Fia Toys as well as a few other large retailers. Thought to date from the 2000s and 2010s. Whilst most of the instructions are headed Nuts & Bolts, a few instructions were in colour and headed 'Construction'. The design and colours of the instructions and logo at the bottom are these are almost identical to Eitech.
