14-10x22-95 CL3 Hex Head Self-drilling Screw

Product Overview
The hex flange head self-drilling screw, also commonly known as a tek screw, is a multifunctional fastener designed specifically for the rapid fastening of metal components. It integrates the three processes of drilling, tapping, and fastening into one, eliminating the need for pre-formed holes. It can complete the installation directly on substrates such as steel plates and color steel tiles in a single operation, drastically boosting construction efficiency. This screw utilizes a carbon steel substrate paired with a Class 3 mechanical galvanizing surface treatment, balancing strength, corrosion resistance, and cost-effectiveness. It stands as one of the most widely applied fasteners in engineering scenarios like light steel structures and roofing building envelopes.

Product Applications
Connecting sheets and purlins in color steel tile roofing and wall cladding systems, suitable for scenarios like industrial plant roofing, prefabricated houses, and steel structure factories.
Fixing components and connecting joists on color steel tile roofing within photovoltaic mounting systems.
Fastening sheets and splicing components in metal curtain walls and light steel joist structures.
Rapidly installing and fastening various thin-walled metal components such as ventilation ducts, light steel industrial facilities, and guardrails.
