A flange bolt is different from a standard bolt. Unlike other bolts, it features a broad surface area beneath the head to render a smooth distribution of securing pressure. This wide space acts as a washer, thereby eliminating the requirement to look for an additional spare for application of such bolts. Specifically in wood to wood, wood to metal, or metal to metal applications. Zinc plated 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.
