In this paper we study the existence of rational points for the family of K3 surfaces overgiven by $$\begin{aligned} w^2 = A_1x_1^6 + A_2x_2^6 + A_3x_3^6. \end{aligned}$$When the coefficients are ordered by height, we show that the Brauer group is almost always trivial, and find the exact order of magnitude of surfaces for which there is a Brauer–Manin obstruction to the Hasse principle. Our results show definitively that K3 surfaces can have a Brauer–Manin obstruction to the Hasse principle that is only explained by odd order torsion.
