Wood-Screw-Threaded Metal Anchors for Block and Brick
Also known as lag shields, these anchors are designed to be used with large-diameter wood screws. They reinforce the hole and resist stripping. Each diameter is available in two lengths. The shorter length reduces drilling time; the longer length provides more strength. To install, tap into a drilled hole with a hammer and position your fixture. Then, insert a lag screw and tighten. Install flush or slightly below the surface. Pull-out strength and shear strength values are 25% of the ultimate values.

Wood Screw-Style Hangers
Drive these hangers into wood with an adjustable wrench, pliers, or a special driver bit (sold separately). They’re also known as eye lags.
Zinc- and zinc yellow-chromate plated steel hangers are corrosion resistant in wet environments. The zinc yellow-chromate plated steel hangers meet quality standards outlined in ASTM B633 and dimensional standards outlined in ASME B18.2.1.
316 stainless steel hangers have excellent resistance to chemicals and salt water. They’re best for corrosive and marine environments.
