In this case study, anchor bolts used to suspend ventilation fans were identified as a critical risk. Correct installations are extremely important, but the fact that maintenance was not undergone because of the placement of such joints requires a rethinking of design. Products to prevent loosening which were previously used, did not prevent loosening leading to joint failure. Current strategies use products which don’t require periodic corrective maintenance and can be observed by the use of a “match-mark”. HARDLOCK® nut allows for easy installation in such hard to install areas with use of a regular wrench, and is recognized for true loosening prevention in critical joints.
