High-strength blue-white zinc plated four-prong nuts feature an electroplated blue-white zinc finish. The coating is uniform, dense, and resistant to peeling, offering superior rust and corrosion protection. The four-prong design provides strong gripping force, preventing slipping or detachment after installation. High material hardness and strong load capacity resist thread stripping and deformation. Precision smooth threads are compatible with various bolts. Suitable for automotive parts, instruments, mechanical equipment, heavy-duty frames, and other indoor/outdoor applications. Economical, practical, stable, and durable.
