Superior performance for coupling bolts

This innovative product replaces large fitted or interference fit bolts, no modifications required. Fast, safe and easy installation and removal.

Incorporating Superbolt technology, EzFit mechanical expansion bolt is able to offer tremendous radial expansion and joint clamping power in one bolting system. The expansion bolts replace traditional interference or force fit bolts. Radial expansion is critical for rotating couplings or alignment systems that require the bolts to be able to transfer forces in shear.

The key to this solution is the split expansion sleeve that mates with the customer’s machined holes. The split sleeve requires less tolerance on mating parts than is traditionally required with interference fit, saving critical machining time. EzFit mechanical expansion bolts are tested and approved by ABS (American Bureau of Shipping), DNV (Det Norske Veritas) and LRS (Lloyd’s Register of Shipping).

EzFit mechanical expansion bolts contribute to a large amount of time saving during the installation process. Watch the video of our on-site installation at EDF hydro electric power station:
