The FastenMaster TimberLOK Structural Screw is engineered for heavy-duty fastening in dense wood and timber applications. These 10-inch screws deliver superior holding power without requiring pre-drilling, making them ideal for deck construction, structural timber assembly, and demanding outdoor projects. Their one-step installation process reduces labor time and complexity while ensuring secure, corrosion-resistant connections in pressure-treated lumber and other challenging materials.
The countersunk head design sinks neatly flush with the wood surface, leaving a clean, professional appearance. An E-coat protective finish guards against corrosion, keeping your fastened connections solid outdoors. With 50 screws per pack, you have plenty for your project needs.
