M8 Aluminum Hex Bolts
Hexagonal head bolts made of aluminum alloy with an M8 thread size (8 mm diameter), used for securing structural components in construction and machinery. Classified under HTS 7616.10.70 because the threads exceed 6 mm in diameter, distinguishing them from finer wire-based fasteners. These bolts meet aluminum alloy criteria with silicon and other elements exceeding purity limits.
