Question: Is this bolt actually metal
Document: Well the diameter of the inner chamber is barely big enough to hold an aspirin. You can fold up a few dollars and put it inside. These are something that you could leave around and no one would be the wiser.This is an actual bolt not some cheap piece of plastic or cast pot metal. Screw the nut on tightly you could leave it to work bench and it would look like it belongs there.
Cool idea, big bolt small storage space. I've used it to Hide keys in a place that blends in well.
fits in with the gear I carry. Looks and feels just like an ordinary bolt. I hope no one I know reads this
This is genius! If you invented and crafted these you should get rich. You deserve it. Didn't leave out any detail. Made it dirty as well! Ha. Too funny. I love it. I just hope no one wants to steal it because it's cool just being a giant bolt. Ty
This bolt safe does not have a lot of room but that is understandable. If it did have a lot of storage room then the bolt would have to be huge, and that would make it noticeable. You should go to the hardware store and buys some more bolts like this one, and it will be hidden quite nicely.
His response was, "I do not state that the bolt has a 2.75 inches hidden area on the page. The only reference I make to size is that it is 3 inches in length closed." Clearly, in the first product picture, it states a 3" closed length.
The Good:  This bolt safe is solid. The construction is exactly what you would expect from a safe made out of a bolt. Heavy duty, durable, and inconspicuous.The Bad:  The picture on the product page (as of the date of this review) states that the hidden compartment within the bolt is 2.75" deep, which is roughly the width of a U.S. dollar bill.
Haven't had to stash anything in here yet  But the opening will be great for whatever small things you might need to stash. Weather it's for traveling purposes or keeping things on the dl at home. Just throw this in a bucket or toolbox with some other bolts and misc washers/nuts and no one will be the wiser. I might even get another no stash boot just to make it look like I needed boots this big. It is a big bolt.
its big for what i wanted it for, pretty much unnecessary not worth my time sending it back most likely just sitting collecting dust now. the thing is too big to hide, if it were smaller it would be different
it's ok would work if mixed in with say tools and other bolts.
Answer: yes
