‘Why fasteners fail after passing the stress test’ - .PDF file.

When a fastener fails because of hydrogen embrittlement, the blame often tends to be unfairly pointed at the supplier. TR Fastenings, a manufacturer and distributor of industrial fastenings, has experienced various cases in the past where large bolted joints have passed the stress test, yet unexpectedly failed in service; however, this has been shown to be due to the way they have been used and not due to any manufacturing errors. If a bolt is designed to hold 100kg and 200kg is applied, it will break. Once installed and in service, environmental exposure can cause analogous situations when stressed above a threshold stress that causes time-delayed failure. Dr Louis Raymond is a materials scientist with more than 30 years’ experience as consultant, educator, diagnostician and forensic scientist. Here, he answers frequently asked questions related to the cause of fastener failures.
