National Mfg N800-123 Lag Screw 1/2 X 1-1/2 Inch Structural

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N800-123 is a hex-head lag screw designed for structural fastening in outdoor wood construction. Measuring 1/2 inch in diameter and 1-1/2 inches in length, this heavy-duty fastener is built for load-bearing applications where standard wood screws are insufficient. It is sold in a package of 12 and is intended for use by contractors, landscapers, and skilled tradespeople working on exterior wooden structures. The coarse thread pattern and large hex head allow for high torque installation using standard socket or wrench tools.

This lag screw is specified for installing decorative hardware collections on outdoor pergolas, flower beds, garden arches, and similar exterior wooden structures. It is rated for structural use, making it appropriate for applications where fastener integrity under load and weather exposure is a requirement. The 12-count package suits single-fixture or multi-point mounting jobs on outdoor builds.

Installation Notes

Installation is typically performed by carpenters, general contractors, or experienced DIYers working on outdoor wood structures. A pilot hole should be drilled prior to driving the lag screw to prevent wood splitting and ensure proper thread engagement. Use a socket wrench or impact driver with the correct hex socket size. Follow applicable building codes for structural fastener spacing and embedment depth when used in load-bearing assemblies.
