Machine Bolts
Machine bolts are heavy-duty fasteners with a square or hex head designed for through-bolted connections in structural steel, machinery bases, and general industrial assemblies. Blue Ribbon Fastener stocks machine bolts in both square head and hex head configurations in hot dip galvanized and plain finishes for use in construction, agriculture, and industrial applications. Square head machine bolts are particularly common in older structural steel and agricultural connections where pipe wrenches and open-end wrenches are the primary installation tools.
Usages for Machine Bolts
Machine bolts are used in steel-to-steel and wood-to-steel connections where the bolt passes completely through both members and is secured with a nut. Common applications include steel building frames, agricultural equipment and structures, conveyor and material handling systems, utility and transmission structures, and equipment mounting pads. Square head machine bolts are especially suited to applications where the fastener will be installed with a pipe wrench, while hex head versions work with standard wrench and socket tooling.
Machine Bolts for all Industries
Machine bolts serve construction contractors, agricultural equipment operators, utility companies, industrial plant maintenance teams, and equipment manufacturers who need a strong, reliable through-bolt in standard or non-standard configurations. Blue Ribbon Fastener supplies machine bolts in both head styles and multiple finishes with the volume availability and competitive pricing that production buyers and project procurement teams require.
