Lag screws are heavy-duty fasteners used to connect heavy lumber or materials that bear intense load. They are widely utilized in construction, framing, and woodworking to create strong, load-bearing joints.
The zinc plating provides a sacrificial layer of rust protection, making them ideal for indoor or sheltered outdoor environments. The eye hook design allows for easy attachment of wires, cables, or suspended components.
Stainless steel lag screws offer excellent corrosion resistance. Grade 304 is suitable for general outdoor environments, while Grade 316 provides superior corrosion resistance in marine, coastal, or highly chemical-exposed applications.
Yes, pre-drilling pilot holes is highly recommended for standard lag screws to prevent the wood from splitting and to ensure smooth alignment. However, some specialized structural lag screws feature self-tapping tips that do not require pre-drilling.
Structural lag screws are engineered with heat-treated steel, high shear strength, and specialized threads. They are designed for fast installation and critical structural load connections, often serving as a modern replacement for traditional hex-head lag bolts.
