ASME B18 2 2 Nuts

ASME B18 2 2 Hexagon nuts with hexagon head screws or bolts used to fix two or more pieces of wood or metal. Hex nuts are often used to construct frames or create bolted connections.

Nuts ANSI B18.2.2 for general applications: machine screw nuts, hexagonal, square, hexagonal flanges, and coupling nuts (Inch series).

Stainless steel, carbon steel, and alloy steel are available to withstand more wear. Since these nuts are galvanized, they are very durable and can be easily used in heavy-duty applications as long as the axial pressure on the body is low. They are also corrosion-resistant. These nuts are mainly used to fasten soft materials and will break if thicker fasteners are used.

Square Nuts Dimensions

A square nut is manufactured in accordance with ANSI B18.2.2 specification, and Class 2B series coarse thread national standard thread after centrifugal hot-dip galvanizing.

Square nut is only a four-sided nut, but compared with the standard hexagonal nut, the square nut has a larger surface area in contact with the clamped part, so it has a greater resistance to loosening.

Hex Flange Nuts and Large Hex Flange Nuts Dimensions

Large flange hex nuts use Spiralock’s patented wedge-shaped inclined internal thread and unique self-locking thread technology, which adds a locking function to the threaded hole.

This function prevents vibration from loosening while allowing standard external threaded parts to rotate freely during assembly.

America standard coating is transparent zinc chromate. Other nut styles, veneers, and materials can be provided on request. The size of the large hex flange nut conforms to the IFI-145 standard.

Heavy Hex Nuts and Heavy Hex Jam Nuts Dimensions

Heavy hexagon nuts and heavy hexagon jam nuts are manufactured in accordance with hexagon nut specifications, such as A563 and A194.

Hex jam nuts are thinner than standard heavy hex nuts but have the same dimensions on the plane and corners. Heavy hex jam nuts are sometimes used for leveling purposes.

Hex Coupling Nuts Dimensions

Hex Coupling Nuts are used to connect two pieces of threaded material. The heavy-duty hex and hex connectors are right-handed threads. 

If the left and right couplers are required, please consider using turnbuckles. Please refer to our nut compatibility chart to determine compatible hex joints for a specific bolt grade.
