Болт для подвеса солнечных батарей

Solar Hanger Bolt with Self-Drilling Tip is a hybrid fastener that combines three critical functions: Self-Drilling Tip: A drill point (like a Tek screw) that eliminates the need for pre-drilling a pilot hole. It drills its own hole through the steel. Bolt Threads (Upper): Machine threads on the top portion, designed to accept a nut.
