An expansion bolt is a mechanical part shaped like a partially threaded rod for the passage of a nut. The bolt is used to create a rigid and complete connection that can be disassembled when needed. Therefore, the expansion bolt allows for the disassembly of mechanical parts for their repair and maintenance. Depending on their type, expansion bolts often have one conical end partially covered with a band of flexible metal.
Expansion bolts come in several models. Some are perfectly suited for ceilings, stone walls, or brick walls. They can also be used for fixtures on concrete structures. Some models of expansion bolts are indeed designed for fixtures on solid and hard supports. According to specialists' advice, the use of an expansion bolt requires a nut and sometimes washers. These accessories enable optimal efficiency in use. Thanks to their use, up to 25% less hammering and 20% fewer turns of the wrench are recorded during fixing. Expansion bolts are mainly intended for DIY enthusiasts and machining professionals. The numerous models of expansion bolts are generally made of steel to ensure impeccable results when tightening heavy loads. It is noted that this part comes in several sizes, diameters, and lengths, considering its diversified use.
