Repeat Order for the World's Largest Hydraulic Nuts

In 2011, bolt tightening specialists, Tentec Ltd received and delivered an order for what was believed to be the largest hydraulic nuts ever manufactured. The contract, to supply 4 massive hydraulic nuts for a major forging press refurbishment project in the USA, was completed and delivered on time and on budget. The quality of the work carried out by Tentec's innovative in-house design and production team in its advanced UK manufacturing facility has resulted in a repeat order for the same company. The hydraulic nuts required for the forging press had 25" Buttress thread forms and each hydraulic nut weighed 4 tonnes with an 8000 tonne bolt load capacity.

Hydraulic nuts are a permanent form of bolt tensioning where the hydraulic nut replaces the conventional hexagon or round nut. With application of hydraulic pressure to the hydraulic nuts, bolt load is generated effortlessly and the user needs only to insert easily fitted shims to retain the bolt load. The hydraulic pressure is then released and an accurate bolt load is retained.

"We are delighted to have received a repeat order for these hydraulic nuts." says Paul Egginton, Engineering Director at Tentec. "The original order was a real challenge but our whole team pulled together and delivered the products to the exacting specifications."
