About Hex Head Screws and Bolts

Designed for construction and exterior building applications, these metric screws are often used to join I-beams and scaffolding. Their partial threading leaves an unthreaded portion that is strong enough to stand up to the sideways forces of joints. Made of Class 10.9 steel, these screws are at least 25% stronger than our medium-strength steel heavy hex head screws. They also have a hot-dipped galvanized finish that makes them 10 times more corrosion resistant than zinc plating, so they won't rust in wet environments. However, this finish is thicker than other finishes, so they should be used with DIN 6916 structural washers and DIN 6915 structural hex nuts. All meet ISO 7412 (formerly DIN 6914), an international standard for screw dimensions.
