This standard PV bolt offers reliable performance and cost-effectiveness for conventional photovoltaic installation projects. Its 304 stainless steel material balances good mechanical strength and long-term corrosion resistance, with 500-hour neutral salt spray test certification to prove durability in outdoor environments. The hexagonal drive design fits most standard hand tools, eliminating the need for specialized construction equipment. The metric coarse thread design ensures tight fitting with pre-drilled PV bracket holes, minimizing vibration loosening risk during long-term wind and rain exposure. It meets multiple international quality standards, providing stable fastening solutions for both commercial and residential photovoltaic systems.
