The Advantages of Expansion Bolts
Upon first look they look slightly complicated, like something from an infomercial that you might as well not even try, just save the money that would surely be lost on purchase. However, expansion bolts can be quite useful, as well as reliable and dependable. Definitely not something you would find in an infomercial. A type of anchor bolt, it is comprised of a bolt, nut and lead sleeve assembly that is able to expand when tightened. While most bolts will have to crack the surface they are placed into, these models instead fill the deformities; not only improving the overall look of the structure, but also firmly strengthening the connection. It is able to create a firm bond and offers an extreme carrying weight. This provides additional advantage in industries that might work in vibratory environments because it helps reduce the risk of crack in the structure. Some industries that make use of expansion bolts include construction, masonry walls, turbines, motor couplings, gears, mining, seating and sign installation.
There are several different set ups when it comes to these products. These include the bold-lead sleeve-tapered nut, the bolt-lead sleeve-metal cone-nut and the tapered bolt-lead sleeve-metal cone-nut. No matter how expansion bolts are assembled, some characteristics remain consistent. For example, the nut and cone are made of steel alloys that are able to offer both strength and corrosion resistance. If they will be exposed to water or other environmental elements, the bolts might also be finished with cadmium and zinc plating for additional protection. Then there is the lead sleeve. This part of the assembly is essential to the expansion bolt. Being a malleable substance, when it is compressed it is able to easily fill the drilled spaces along with any cracks or pores surrounding it. This allows it to attach in multiple points without needing to worry about the product cracking or shattering the material it is anchored in.
