A J-Bolt is a fastener shaped like the letter "J," with a curved hook at one end and a threaded section at the other. The hook is typically used to anchor or secure objects to a surface, such as attaching to a structure, a post, or a beam. The threaded end allows the bolt to be fastened with a nut, creating a secure connection. ... J-Bolts are commonly used in construction, foundation work, and heavy-duty applications like securing equipment, signage, or supports. Made from materials like steel, stainless steel, or galvanized steel for corrosion resistance, they offer strength and stability in a variety of industrial, commercial, and residential settings.
