TimberLOK No. 10 X 4 In. L Hex Epoxy Coarse Wood Screws 50 Pk

FastenMaster TimberLOK wood screws are heavy-duty fasteners engineered for demanding structural and outdoor construction projects. These 4-inch screws replace traditional 3/8-inch lag bolts and are designed to drive directly into the densest woods and pressure-treated lumber without pre-drilling, saving time and labor on jobs like deck building, fence installation, rafter attachment, and landscape timber work.

With their sharp point, aggressive threads, and epoxy-coated steel construction, TimberLOK screws penetrate quickly through hardwoods, softwoods, and ACQ pressure-treated lumber. These screws are approved for use in pressure-treated wood and offer corrosion-resistant performance, making them ideal for long-lasting installations in structural and outdoor environments.
