Nuts and Bolts (Construction) Construction Sets
'Nuts and Bolts' metal construction sets had identical parts to Eitech Construction. It was manufactured in the China by Polylong. Thought to date from the 2000s and 2010s. Note that although the set boxes had the name 'Nuts and Bolts' on them, the instructions were headed 'Construction'. The design and colours of the instructions and logo at the bottom are almost identical to Eitech. Looks to be very much a clone.
