supplier in the chain, covering forging, 
heat treatment, turning and thread 
rolling. Acting as the main contractor, the 
company checked compliance with the 
drawing at every stage before authorising 
progression to the next operation.
EFS is a TÜV-certified Italian company, 
and every stage of this order was 
completed in Italian workshops using 
European raw materials.
The finished bolts arrived with straight 
shanks over the full 560 mm length, 
correct tolerances and the required 
seating performance, delivering the result 
that the original manufacturing attempt 
failed to achieve.
