		In construction and engineering, misaligned bolt holes will need to be aligned. For small holes in light workpieces, this can be done using an aluminium wrecking bar.

		If bolt holes are not properly aligned, bolts may be fastened at an angle, loosening the connection between ‘mating’ objects. This can result in structural instability.

		To align misaligned bolt holes, just follow these simple steps:

		Step 1 – Insert conical point into first hole Push the conical point of your bar into the first or top hole.

		Step 2 – Insert conical point into second hole Now locate the second hole and push the conical point of your bar through it.

		Step 3 – Align holes Using a gentle levering action, lever the mating workpieces around the conical point of your bar until the two holes are properly aligned. In some cases, this may take a little time, so be patient!

		Step 4 – Withdraw bar Now you can withdraw the bar from the holes. Simply slide it out, being careful not to push the holes out of alignment.

		Step 5 – Check alignment Check that the holes are still in alignment. If not, repeat steps 1-4 until you are confident that the holes are aligned properly.

		Step 6 – Insert bolt Once the holes are properly aligned, you can fasten the two workpieces together using a bolt. Simply insert the bolt and tighten with a spanner of the appropriate size and type.
