Finished boltDrawing-defined acceptanceNo grade-specific finished-bolt specification was established in the reviewed sources.
Define final annealed condition, mechanical acceptance and inspection for the drawn bolt; a heat-resistant material name alone gives no strength class.
The producer bulletin cites the older BS HR 5. BSI states that BS 2HR 5:2010 supersedes BS HR 5:1972; retain an older callout only when the order explicitly requires it.
Raw material specificationBS 2HR 5:2010UNS N06075
N06075 / Nimonic 75 · form-specific material route
HR 5A identifies annealed machining bars; HR 5C forging stock and HR 5D forgings are different forms. Select the applicable designation.
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
Which BS reference applies to Nimonic 75 bolt stock?
BS 2HR 5:2010 distinguishes HR 5A annealed machining bars, HR 5C forging stock and HR 5D forgings. It supersedes BS HR 5:1972. Select the form that matches the manufacturing route and retain an older edition only when explicitly required.
What should accompany an Nimonic 75 bolt drawing?
Include quantity, the selected stock designation and final condition. For thermal service, add atmosphere and loading duration, together with required mechanical tests. The material reference supplies the stock basis; the drawing and acceptance plan define the finished bolt.
