The Metric size range for the Hex Head Bolt starts from M2 and goes up to M72. This makes it ideal for a wide range of applications that require fastening with metric sizes. The Hex Head Bolt is designed with an external hex drive type that ensures a secure grip when tightening or loosening the fastener. The hexagonal shape of the head allows for easy tool access and provides a larger bearing surface for distributing the load.
The Zinc Plated finish of the Hex Head Bolt provides excellent corrosion resistance and adds an aesthetic appeal to the product. The electroplating process used to achieve the Zinc Plated finish results in a bright, shiny surface that is resistant to rust and oxidation. The finish also improves the durability of the fastener, making it ideal for use in outdoor or harsh environments.
The Hex Head Bolt has a Proof Load of 85,000 Psi. This means that the product can withstand a certain amount of tension and compression without breaking or deforming. The Proof Load is an important factor to consider when selecting a fastener as it ensures the safety and reliability of the application.
