The 1/2-13X3-1/4 Grade 8 Hex Flange Bolt is engineered from Grade 8 steel, offering high tensile strength and hardness essential for demanding structural applications. Its quenched and tempered alloy composition ensures long-term joint integrity, making it suitable for scenarios where a high clamp load is critical.
The coarse thread pitch facilitates quicker assembly and disassembly, optimizing efficiency in projects where time constraints are a factor. The hex flange design provides a larger bearing surface, enhancing load distribution and reducing the risk of fastener loosening.
Finished with a yellow zinc chromate coating, this bolt provides improved corrosion resistance over clear zinc, making it suitable for mild outdoor exposure. This finish helps extend the fastener's lifespan by protecting against environmental elements, though it may not withstand marine or chemically harsh environments.
