Nord-Lock Group Superbolt EzFit

EzFit mechanical expansion bolts offer tremendous radial expansion and joint clamping power in one bolting system. They are specially designed for rotating couplings or alignment systems that require the bolts to transfer forces in shear. This innovative product replaces large fitted or interference fit bolts, no modifications required. The key to this solution is the split expansion sleeve that mates with the customers' machined holes. The split sleeve requires less tolerance on mating parts than is traditionally required with interference fit, saving critical machining time.
