Buying advice

When selecting lag screws, consider the material (steel, stainless, galvanized), thread type (coarse vs fine), head style (hex, washer, etc.), and length/diameter as per your project. Always pre-drill pilot holes to avoid wood splitting, especially near edges. For outdoor use, prefer galvanized or stainless steel for corrosion resistance. Check load requirements and use appropriate driver bits to prevent stripping.
