Product Details

This product is a “dedicated matching nut” for 4.8 grade hex bolts. Manufactured to dual standards, it is suitable for both domestic and international projects. Its 4-grade strength precisely matches the 4.8 grade bolt, making it a fundamental accessory for steel structure auxiliary connections. In steel structure auxiliary connections, the nut’s strength does not need to be excessively high; a 4-grade nut is perfectly adequate for load-bearing requirements. It is also inexpensive, highly adaptable, and an essential item for bulk purchases by engineering companies, as well as a core small category for trading companies to replenish their stock. The product features clear, burr-free threads, smooth tightening, and compatibility with various 4.8 grade bolts. A full range of specifications are in stock, with short delivery times and extremely high cost-effectiveness.
