Heavy Hex Nuts

Heavy Hex Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads’ friction, a slight stretch of the bolt, and compression of the parts. Al Khamisain provides heavy hex nuts that are extensively used in various application areas. These hex and heavy hex nuts are available in large and small sizes in various grades and finishes.
