Could a stainless steel 5/16-18 bolt replace a 5/16-18 #5 harden bolt?
Other words would a stainless-steel bolt be as hard as a #5 bolt?
I'm guessing 304-stainless steel.

...... Cancel this question, I just learned that the stainless steel is a little more than a #2 grade ......
...... Sorry I tried to cancel the question, but the system would not let me.

Weighs less than aluminum but is stronger than steel! You can’t make a knife out of it either because it is impossible to sharpen! I tried!

I used a titanium turbine fan blade out of a generator. My dad had worked at a power plant. There was nothing I could use on it to sharpen it. Find out how she did it. Because a wet stone, oil stone or diamond stone won’t touch it!

dad wants to know how you made it from a turbine blade to knife shape. he says if you forged it, the titanium can react with oxygen forming a titanium alloy NOT TITAINIUM OXIDE thats not fun to get off or grind through.

Not forged, dad took and gave it to a machinist at work and they spent weeks and many bits with a mill trying to make a 6” knife! Then I have spent decades trying to sharpen it. I’ve come to the conclusion it can’t be done!

Cavemen sharpened rock tools
...with harder rocks :thumbsup:

Define "sharpen"
...like simply "bring the edge of the material, to a point"?
...or establish an "edge"?

Um...Have you tried making a slurry or paste with that Saw-Glu stuff? :innocent::devil2:

I'll betcha that stuff will "sharpen" 'er right up :bannana:

I’ll bet it won’t. I’m talking about an edge to be able to cut stuff with! Like I said diamond stones won’t do it!

hmmm, titanium, according to my dad, isnt all that hard. you should be able to attack it with an angle grinder. maybe you got a funny alloy.

A new bolt question the two symbols on these boats indicate that it is a hardened Bolt? I know the letters does not indicate a hardened bolt but I was wondering about the symbol under the lettering? These boats are American 3/8" x16 TPI.
