Product Details

This product is a “basic general-purpose” fastener for steel structure engineering. It is a 4.8 grade fully threaded hex bolt, manufactured to both domestic and international standards. It belongs to the category of light-duty load-bearing fasteners and is specifically designed for non-core load-bearing components such as steel structure accessories, railings, ladders, and door and window frames. In steel structure engineering, most accessory connections do not require high-strength bolts; 4.8 grade bolts are perfectly adequate for load-bearing requirements. They are also inexpensive, making them a basic category for bulk purchases by engineering companies and a frequently replenished item for trading companies. The product features high thread precision, smooth installation, and compatibility with various light components. A complete range of specifications are available, with short delivery times and extremely high cost-effectiveness. It is a “basic essential” fastener for steel structures; without this product, it is impossible to complete the accessory connection process.
