T17 Hex Head Screw 12–11×35 CL3 (Head Blue Powder Coated RAL-5017)

Product Overview
The hexagon flange head blue powder-coated self-tapping screw is a high-efficiency fastening connector specifically designed for outdoor cladding, light-gauge steel, and wood structure applications. It combines the quick-installation feature of self-tapping screws, the stable load-bearing design of the hexagon flange head, and the weather-resistant anti-rust process of blue powder coating. It can be driven directly into substrates such as wood and thin steel sheets without the need for pre-tapping or pre-drilling. Widely used in projects including color steel tile roofing, light-gauge steel framing, and panel splicing, it is a versatile fastener that balances installation efficiency, connection strength, and visual consistency.

Product Applications
Fixing color steel tiles and profiled steel sheets to the roofing.
Assembling light-gauge steel framing and wooden frame structures.
Splicing thin steel sheets, aluminum panels, and other sheet materials, as well as installing outdoor fixtures.
