Products Description
The Chicago screws consist of a pair of matching screws, including a male screw with an external thread and a female screw with an internal thread. This design allows them to securely connect two working pieces, and the connection points can be adjusted to suit different hole depths.
The Chicago screws are made of stainless steel (SS201, SS304, SS316), brass (C36000, C37700), bronze, carbon steel, alloy steel, and aluminum. Surface treatment methods are also rich and varied, such as galvanizing, nickel plating, passivation, sandblasting, anodizing, polishing, electrophoretic coating, black anodizing, chrome plating, etc., to meet different appearance and anti-corrosion needs.
Our Chicago screws are made of stainless steel.
