Heavy Hex Nuts

Define the part. Align the requirement.

Heavy hex nuts should be specified as part of the complete bolted assembly. Cyclone’s published catalog includes ASTM A194 2H, Grade 8 and Grade 8M configurations. State the companion stud or bolt, required thread fit and finish so the team can review matching hardware and documentation.

Published grades

A194 2H, Grade 8 and Grade 8M appear in the catalog. Identify the required grade, class or condition and the governing specification revision in the order.

Diameter range

Heavy hex nuts are available in nominal diameters from 5/8 inch through 4 inches. Provide the required dimensions, grade and quantity with the RFQ; the team confirms availability and delivery.

Finish options

Published 2H listings include plain, TFE blue and cadmium-plated options. Specify the complete finish requirement and any thread allowance or inspection requirements.

Receiving requirements

Identify required marking, material reports, lot traceability, thread gaging and packaging. Nut and stud compatibility must follow the responsible engineer’s assembly specification.

Questions before you quote

Can nuts be supplied as part of a stud set?

Yes. Identify the stud specification and number of nuts per set, then list material, finish and documentation requirements for each component.

Are Grade 8 and Grade 8M the same nut?

They are separate A194 grade designations. Order the exact grade, class and condition required by the assembly specification; do not substitute on appearance.

Does the range table show live stock?

No. The table summarizes the product range. The team confirms availability, order quantity and delivery during quote review.
