Drawing of round head rivets, 1898 A typical technical drawing of a universal head solid rivet Riveters work on the Liberty ship SS John W. Brown (December 2014).. Rivet holes have been found in Egyptian spearheads dating back to the Naqada culture of between 4400 and 3000 B.C.

An adjustable die may be adjusted either by an integrated screw or by a set of screws set in to the die holder (termed a "die stock"). Integral adjusting screws may be arranged to work axially, where the movement of the adjusting screw into a threaded hole in the die forces the slit section of the die open, or tangentially where a screw ...
A Robertson screw, also known as a square screw [1] or Scrulox, [2] is a type of screw with a square-shaped socket in the screw head and a corresponding square protrusion on the tool. Both the tool and socket have a slight taper .

The extractor is pressed against the damaged head and rotated counter-clockwise and will tend to jam in the damaged head ...
A pentagon screw drive uses five-sided fastener heads, and the fastener is known as a penta screw or penta bolt. It is designed to be intrinsically incompatible with many tools. Since five is an odd number, it cannot be turned by open-end or adjustable wrenches, which have parallel faces (and thus require a fastener with an even number of sides).
