I want to find a bolt like the one attached in this post. It has hex slot, the diameter is 1/4" in the shank. and the length is about 0.9". This is from a chair. I want to find a bolt just like this but with slightly longer shank--maybe 1.25" at most. The problem is this short bolt causes the chair back support to be tilted toward the front. If I can use a slightly longer bolt the back support can be pushed back a little bit. Can I get help finding the name of the product, and if possible, where to find this kind of bolt? I've tried to scour internet with no good result.

Grade-8 bolt, hex slot, 1/4" diameter.

 

Just about any good local hardware store should have a bolt that will work for you.

 

#1, There's no reason a chair would need a grade 8 bolt.
#2, Any longer bolt with a washer should work.

 

Take a look on McMaster web site, it it's a product for sale, they have it!

A standard hex head bolt with a washer would work to replace that. No need for the integral washer nor hex-drive head. As long as you can tighten it, it's not a big deal.
The 'assemble your own' furniture suppliers like those bolts as it's cheap to include a hex key with the furniture for customer assembly. One of those cheap metal wrenches are harder for most people to use, and it would be"expensive" for them to include a proper assembly tool.

As Marq mentioned, I'm sure you could get a box of 50/100 at McMaster Carr, but your local hardware store will sell you one for about $0.21.

 

Thanks all who reply! I will look at my hardware store & see what I can get there.

Keep in mind it doesn't likely need to look exactly the same.

They will likely be found in the hardware drawers in the bolt aisle.
