I stripped some parts from a large tower at a junkyard.
I saved the nuts and bolts just because I was curious.
The bolts are 5/8" x 1-1/2" long with the marking Kaiser.
The bolts, nuts and even the lock washer are all very light weight.
The lock washer is a slightly different color.
I don't think they are aluminum, I don't think it would have enough
strength. I used a file and gathered some filings and tried to burn
them, they didn't burn so I don't think it is magnesium.
Any idea what metal these bolts might be?
