Listed here are machined aluminum Button Head Cap Screws.

 

These are very similar to the Allen Cap design we know of except these have a rounded "low profile" dome head very much like a rivet.

 

There is a shallow drill bore in the top of the head to represent the hex keyhole. Most of my general sales for this product have been for replicating rivets on large scale projects and 1/12 scale F-1body and wing fasteners.

 

Please note that stem lengths on this part will vary.
