For blind hole applications
Expansion bolts - blind hole applications
This innovative product replaces large fitted or interference fit bolts, no modifications required. Fast, safe and easy installation and removal.
Nord-Lock Expansion bolts for blind holes are radially pretensionable fitted bolts. As stud in tapped bore they replace fitted bolts, which are difficult to install and remove. The Expansion bolt for blind hole can be tensioned axially. Due to the radial pre-load, the joint experiences can increase in rigidity, therefore eliminating micro-movements between the parts. Our Expansion Bolts incorporate Superbolt multi-jackbolt tensioners and are fully mechanical elements and therefore reusable.
