Thank you very much for your inquiry. As this web site is a dedicated resource center, we do not actually sell any fasteners from here. I have taken the liberty of forwarding your request to our commercial site ( http://www.aspenfasteners.com ) who can be reached at any time by email ( aspensales@aspenfasteners.com ) or by phone (1-800-479-0056 ).
Many thanks for taking the time to contact us.
I am looking for a machine bolt that I specified some time ago, similar to an elevator bolt but higher head, that seems to have no observable driver mechanism. It is actually an oval shape that with the reciprocal driver head it can be tightened.
Does this sound like anything you have come across?
It sounds to me that you are looking for a Carriage Bolt as this is a similar fastener design as an Elevator Bolt and does have a higher and rounded head. You can take a closer look at Carriage Bolts here: http://www.aspenfasteners.com/Carriage-Bolts-s/75.htm. Is this what you had in mind?
Carriage Bolts, like Elevator Bolts, have a specifically shaped portion of the shank, right under the head of the fastener, that provides the locking/holding mechanism during assembly that would normally be taken care of by the head style or drive recess of fasteners like Hex Bolts (http://www.aspenfasteners.com/Hex-Head-Tap-Bolts-s/130.htm) or Socket Cap Screws (http://www.aspenfasteners.com/Socket-Products-Socket-Cap-Screws-s/1139.htm).
In the case of Carriage Bolts, the most common locking/holding mechanism is the “square neck” (http://www.aspenfasteners.com/Carriage-Bolts-Round-Head-Square-Neck-s/79.htm). Another variation would be the “ribbed neck” (http://www.aspenfasteners.com/Carriage-Bolts-Round-Head-Ribbed-Neck-s/89.htm). Less common is a Carriage Bolt with an oval shaped neck that is sometimes referred to as a “Track Bolt”. This is an older design that is not commonly used anymore.
I hope this answers you questions. If not, please feel free to get back to us and we’ll try to help you as best we can!
thanks for your response but those are not what I am looking for. Imagine a bolt that looks like
http://fastenerstation.com/showroom/index.php?cPath=23
this low head screw but instead of the allen head drive it is flush on the top. It is held by changing the circular shape to an oval (but not recognizable). the other end take what ever nut you desire. So the driver, to hold it, is the opposite of the oval. In other words an inside oval (similar to a socket wrench but smooth and ovular. Is that clearer?
Your description is clearer, but we are still not recognizing the part you are looking for.
Based on your description, we are thinking that this may be some form of a T-Bolt. Please take a look at these image links and let us know if we are getting any closer:

image 2: http://image.made-in-china.com/2f0j00kertzjYcEnqm/T-Bolts.jpg
Now, if you happen to have a sample of the part that you are looking for, may we suggest that you to take a picture of it and email it to us at aspeninfo@aspenfasteners.com.
I suppose you are right it is most like a T-Bolt but the top is flat and more like the bolt that I mentioned previously. I am thinking it most looks like a binder bolt but with a higher profile.
The problem with side gripping (bolt) the hole is that it is going into a plastic resin material known as 3form which, I fear, is not forgiving and will likely crack when pressure is put on it.
Your mention of 3-Form is quite interesting. Are you aware that they have a page dedicated to hardware solutions for this material? I wonder if this will be of help to you:
http://www.3-form.com/solutions-hardware.php
thanks I’ll check that out
on another project do you know of a inexpensive source of a “house-mate 7mm x 50mm hex in zinc or chrome ?
From what I can tell, “house-mate” seems to be a Home Depot brand so finding the specific part you are looking for was relatively easy:
http://www.homedepot.com/h_d1/N-5yc1v/R-202105609/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053
The generic description to the part you are looking for would be a Pancake Head Hex Socket Drive Wood Screw. These might also be referred to as Furniture Screws.
Searching on these descriptions, you can find sources ranging from Asian manufacturers to more local distributors, depending on the quantities you are looking for. From what I can see, if you are only looking for a handful of these screws, Home Depot might be the right source for you.
