Full Thread Hex Bolts with Hex Nuts (M16-M20, Grade 8.8+)

• Heavy-duty fully threaded hex bolts with matching hex nuts, likely M16-M20 size range and long length. • Yellow zinc/gold passivated coating provides excellent rust and corrosion resistance, suitable for outdoor and industrial environments. • Suggested Grade 8.8 or higher structural grade, indicated by the yellow finish and thick shank, ideal for demanding applications. • Commonly used for steel structures (buildings, bridges), flange connections (pipelines, oil & gas), and heavy machinery mounting. • Hex head on bolts and hex nuts ensure secure tightening with standard wrenches. • Offers superior corrosion resistance compared to plain black bolts, extending lifespan in harsh conditions.
