L.H.Dottie® Hex Head Lag Screw, Stainless Steel, 5/16" x 3-1/2", 100 Pack

Lag Screws are heavy duty fasteners used to connect heavy lumber or other materials that bear a strenuous load. They are manufactured from low carbon steel and can be used with lag shields in a variety of masonry applications, such as concrete, brick, and mortar. Lag Screws can also be used where standard wood screws are too short or small. In some applications, a pilot hole may be pre-drilled to prevent splitting or snapping. ASME B18.2.1 cover the requirements for steel lag screws.

Screws are intended for use in hygienic design applications, the sealed flange surface enables components to be mounted without dead spaces. The high quality finish as well as the large corner radii and closed surfaces prevent adherence of dirt and facilitates cleaning. Sealing Ring Material made of Hydrogenated Acrylonitrile Butadiene Rubber (H-NBR)
