This 1/4 x 3 inch lag screw features a hex head and zinc plating. It is specified for applications requiring a durable, corrosion-resistant fastener for wood or with lag shields in masonry. The zinc finish provides a sacrificial barrier against moisture, extending service life in damp environments compared to plain steel fasteners, which are susceptible to red rust quickly.
Lag screws secure heavy loads to wood framing, such as machinery mounts, shelving, or utility boxes. They are also used with lead or plastic lag shields in concrete block or poured concrete. The zinc plating retards surface corrosion, maintaining appearance and thread engagement over time in non-aggressive indoor or covered outdoor settings.
