Expansion bolting

For blind hole applications
Radial expansion is critical for rotating couplings or alignment systems.

For through hole applications
Radial expansion is critical for rotating couplings or alignment systems.
Expansion bolting
Our Expansion bolt is a clever design that replaces traditional interference or force fit bolts. The key to this technology is the split expansion sleeve that mates with the customer’s machine holes, along with an internal taper that accepts a mating tapered stud. The split sleeve requires less tolerance on mating parts that is traditionally required with interference fit or hydraulic systems, saving critical machining time. Integrates multi-jackbolt technology.
