Product Details

Hex nuts are to be used with machine bolts to adhere facing materials to prevent tension and shear movement. Zinc grade 5 steel hex nuts are recommended for most outdoor construction uses and are corrosion resistant. Be sure to pre-drill any holes and to use washers and bolts that are a similar grade and finish.
