Standards & threads
Finished boltDrawing-defined acceptanceNo grade-specific finished-bolt specification was established in the reviewed sources.
Define final aged tensile / yield / hardness requirements, and stress-rupture test temperature, stress and duration if the design requires that test.
80A material qualification and a finished hex-bolt acceptance plan are separate. The exact N07080 coverage is supported by the linked B637 grade table.
Raw material specificationASTM B637UNS N07080
N07080 · bar, forgings and forging stock
Identify solution and aging treatment, stock form and the required material tests.
Dimensions · metricISO 4014 / ISO 4017Coarse pitch · partial-thread bolts / full-thread hex screws
Dimensions · inchASME B18.2.1Inch hex bolts / hex cap screws
Select the bolt or cap-screw pattern, head dimensions and thread length. Hex and heavy hex are different choices.
Threads · metricISO 261 / ISO 965-1Metric M · pitch plan and tolerance system
Threads · UNC / UNFASME B1.1Unified inch · coarse / fine series
State diameter, TPI, series and external class: e.g. 1/2-13 UNC-2A or 1/2-20 UNF-2A. Select 2A / 3A with the mating-thread fit; UNC and UNF do not mate.
Mechanical testing ASTM F606/F606M
Mechanical test methods for fasteners; select applicable tensile, yield and hardness tests. This standard supplies methods, not a material grade or pass/fail limits. Define those limits and sampling in the part specification.

Before production and at delivery
During quotation, a redacted certificate from a previous order can show the document format and recorded tests. It is a historical example, not certification of this product or a new order. Shipment documents must correspond to the material and batch actually supplied.

Technical help
What condition should I specify for Nimonic 80A bolts?
Name the solution-treatment and aging route, stock form and required final mechanical properties. N07080 identity and a B637 stock reference should accompany that condition so competing quotations use the same acceptance basis.
When should an 80A enquiry include stress-rupture testing?
When the design or purchase specification requires it for sustained high-temperature loading. Give the test temperature, stress, duration and acceptance criteria. Keep this requirement separate from room-temperature tensile or hardness results.
