The most pure covalent bond will be between two identical atoms, since the electronegativity difference between the atoms is zero.

F and F.
Covalent bonding is an intramolecular form of chemical bonding characterized by the sharing of one or more pairs of electrons between two components, producing a mutual attraction that holds the resultant molecule together. Atoms tend to share electrons in such a way that their outer electron shells are filled. Such bonds are always stronger than the intermolecular hydrogen bond and similar in strength to or stronger than the ionic bond.
In contrast to the ionic and metallic bond, the covalent bond is directional, i.e. the bond angles have a great impact on the strength of the bond. Because of the directional character of the bond, covalently bound materials are more difficult to deform than metals. The cause of the directionallity is the form of the s, p, d, and f orbitals. In organic chemistry the directionality of the bonding is often described by hybrid orbitals.

well, i would definitely go with NaCl, Sodium Chloride or commonly known as the table Salt. Why? With it's distinctive characteristics, it needs a very high temperature...WAIT! You cannot say Na and Cl are covalent bond, they are actually Ionic Bonding - bonding between metal and non metal....so i should correct you....by saying H & F, it's possible since both are non-metal (covalent bonding). Anyway to check whether they are pure covalent bond, we could check its melting and boiling point...

F-F. covalent bonds are formed with things on the same side of the periodic table. the rest are ionic. know thy basics and know how to use the periodic table!

Difluorine F-F: covalent bond, alright :-)
But i also think about Chloronium fluoride F-Cl: i am not sure it is a pure ionic bond. I think it can give (fluoride anion + chloronium cation) or (radical F. + radical Cl.). So...
All I know is that chloronium fluoride, bromonium fluoride, bromonium chloride exist.
