One of our last job. A rounded bolt that cannot be removed. Due to the internal routing and the snug housing hole size, the hardware needs to be removed before routing can be achieved.
Herein, the rounded bolt was drilled thru after bolt extractor has failed. The rivet nut hole was inspected & found to be widen. The hole was patched and shaped, strength further before inserting the rivet nut.
A slow process as each stage was checked, inspected, and escalated to the next plan whenever the basic options are exhausted.
After a few hours, we are glad that the operation was successful.
Bolt extraction is not as straight forward as it seems sometimes.
