Hillman 5/16 in. D X 3-1/2 in. L Zinc Plated Steel Hex Tap Bolt 50 pk

Hex tap bolts are fully threaded machine bolts, designed to adhere facing materials to prevent shear movement; specifically for use in wood to wood, wood to metal, or metal to metal applications. Zinc, grade 2 hex bolts are recommended for most general uses and are corrosion resistant for typical use. Be sure to pre-drill any holes and to use washers and nuts that are a similar grade and finish. *
