Finished boltASTM F468 — inch / ASTM F468M — metricMonel 400 · N04400 · select the unit-specific specification
Specify the applicable finished condition, mechanical tests and marking; bar hardness alone is insufficient. F468M scope is M6–M36; this is a standard boundary, not a stock range.
Do not substitute age-hardened K-500 or free-machining 405 under a generic Monel name. Keep N04400 and the required finished condition on the order.
Raw material specificationASTM B164UNS N04400

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.

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
How do B164 and F468 apply to Monel 400 bolts?
B164 covers the N04400 stock route. F468 and F468M provide separate inch and metric finished-fastener routes within their scope. Identify the required condition, tests and edition in addition to the bolt dimensions.
Can K-500 or machining grade 405 be supplied as Monel 400?
Keep N04400 explicit on the order. K-500 has a different strengthening route, while 405 is a different machining grade. Any change needs a review of material identity, final properties and service requirements before acceptance.
