The critical value for a two-tailed test with $\alpha = 0.10$ (10% significance level) is $\pm 1.645$. This is because the tails (each) contain 5% of the area under the normal distribution curve, and the z-score that corresponds to the cumulative area of 0.95 (or 0.05 in the lower tail) is $\pm 1.645$.
