Flange Hex Head: The bolts feature a hexagonal flange head design that provides a wider surface area than standard bolts, providing an enhanced grip during installation and more evenly distributing the load, meeting DIN6921 specifications2. Hex flange head bolts are widely used in furniture assembly, office equipment, communication devices, shipbuilding, and machinery. Allowing for quick and efficient installation with wrenches or sockets, ensuring strong and reliable connections in both home and industrial settings.3. 304 stainless steel flange hex head bolts offer high hardness, good toughness, and wear resistance. Surface cleaning treatment increases hardness and wear resistance, allowing it to maintain its sharpness and machining efficiency for longer.4. Tips: Ensure that the selected bolt size matches the application requirements to avoid overloading or failure. Additionally, when using a wrench to tighten the bolt, appropriate torque should be applied to prevent over-tightening, which can result in stripping threads or loosening.
