Carbon Steel DIN 6914-1989 High strength bolts with large hexagon head
Product Overview:
High strength bolts with large hexagon head is a kind of high strength, high reliability fastener, specially designed to meet the fastening needs of steel structure engineering. It complies with DIN 6914, ensuring strict quality control and uniform dimensional specifications in the production process. The bolt is known for its unique large hexagonal head design, which not only makes it easy to tighten with various tools, but also increases the contact area between the bolt and the nut, thereby improving the stability and load-bearing capacity of the connection.

Carbon Steel DIN 6914-1989 High strength bolts with large hexagon head Details
High-strength hexagon bolts with large widths across flats for structural bolting thread specifications range from M12 to M36, with a pitch varying from 1.75mm to 4mm. The material is carbon steel. The surface treatment of large hexagonal bolts of steel structure is varied to improve its corrosion resistance, beauty and service life. Common surface treatment methods include hot dip galvanizing, dacromet, electric galvanizing, blackening and so on. These treatments not only enhance the corrosion resistance of the bolt, but also increase its compatibility with the connection material.
