The functionality of metal expansion nuts centers around the principle of mechanical expansion. Upon the application of torque, the screw or bolt is threaded into the nut, which, in turn, causes the nut to expand outward. This outward expansion presses the sides of the nut against the inner walls of the hole it occupies, creating a tight fit. The added friction and mechanical grip prevent the nut from loosening over time, even in dynamic conditions.

1. Construction Builders often use self-tapping bolts to fasten metal framing components or attach hardware in structural applications. Their ability to work without pre-drilled holes is a significant advantage in construction projects.

Another advantage is the ease of installation. Standard wedge bolts can often be installed without the need for specialized tools, allowing for quicker assembly and reducing labor costs. This makes them an attractive option for construction projects that demand efficient time management.

In an effort to provide best-in-class industrial solutions, a renowned manufacturing company has launched a new range of high-quality black flange bolts in various sizes. The new product line includes DIN6921 hexagonal flange bolts, designed to meet the needs of various industries that rely on strong and reliable fastening solutions.
