This listing is for 4 titanium Torq-Set fasteners, specialized for the sensitive aerospace industry.
Three are countersunk flat head screws, a style used on the surface skin of the aircraft which provide an aerodynamic flush finish. At least one still has black paint on the surface.
The last piece is the head of a larger size bolt. The extreme force required to rip this piece in half is evident from the stress marks on the torn end.
The sale price includes the item(s) pictured, verified provenance, & certificate of authenticity. These items will come in an acrylic box.
