180403 Hex Nut, Coarse Thread, 5/16-18 Thread, Steel, Yellow Dichromate, 8 Grade

Hex nuts are to be used with machine bolts to adhere facing materials to prevent tension and shear movement. Specifically in wood-to-wood, wood-to-metal or metal-to-metal applications. Tri-alloy grade 8 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.
