this came off of a bookshelf. it looks similar to a sex bolt but i cannot find one that is exactly the same as this. the one on the left is threaded so the other fits into it. any ideas?

Do your bolt heads hold up shelving? What is the collar under the head for? If it doesn't, then a properly sized sex bolt should work just fine. Google "Sex bolt".

 

That sex bolt is part of a hidden cabinetry fastener system. Check out the following link.
This company offers the bolts as well as the shelving clips. Maybe they'll work for you.

You da man Pete! ...............

 

Pete you are awesome! I spent hours trying to identify this thing. Apparently it is a very niche market. I got the shelves from a video store that was closing and the link you gave me says they make fasteners for video store shelves. Thank you so much. And yes, chandler, it does hold up shelves so the collar is needed. Does anyone know of any local retailers that might have them? I really just need one.

 

wow, i contacted the company and asked where i can buy one and they offered to send me a sample.
