Drop Engineering Lug Nut Kits Drop Engineering lug nuts are carefully crafted from AL7075-T6. T6 temper 7075 Aluminum is an aircraft quality alloy, boasting an impressive ultimate tensile strength of 74,000 - 78,000 psi (pound per square in) and minimum yield strength of 63,000 - 69,000 psi. This level of strength guarantees that the Drop lug nuts will hold up even under the most demanding racing conditions. Drop Engineering forges all of their lug nuts from AL7075 because it guarantees the greatest level of tolerance without any added weight.
