Features Low-strength steel fully threaded rods and studs provide good strength and durability for everyday fastening applications. Steel fully threaded rods and studs are fasteners that provide good strength and durability for a variety of everyday fastening applications. They are made to meet certain strength requirements, indicated by an ASTM grade rating (inch fasteners) or a class rating (metric fasteners). These steel fasteners have males threads running their entire length for full engagement of nuts when assembling components.
