ASTM A194
Grade 8R
Specialty Nuts
An Honest Starting Point on This Grade
We want to distinguish this page clearly from our Grade 8N, 8P, and 8MN pages. On those, even where we couldn’t confirm the exact composition figures, we recognized the letter pattern as pointing toward a specific, known strengthening mechanism — nitrogen alloying, molybdenum plus nitrogen. Grade 8R doesn’t offer us that same footing. We don’t have a confident basis for reading “R” as any particular alloying element, heat treatment, or condition, and we’d rather say that plainly than invent a plausible-sounding story.
There are a few honest possibilities worth naming — this could be a genuine, if very uncommon, ASTM A194 designation we simply haven’t encountered with enough frequency to recall confidently; it could reference a specific project or customer-internal naming convention rather than a standard ASTM grade; or it could be a transcription variant of a nearby, more familiar designation. Without your governing document in hand, we can’t distinguish between these possibilities.
What we can offer confidently is our manufacturing capability and process — if you can share the governing ASTM A194 edition, a project specification sheet, or an existing mill certificate referencing this exact grade, we will confirm what it actually is, verify manufacturability, and quote accordingly.
Akbar Fasteners Pvt. Ltd. exports to over 50 countries and has experience sourcing and manufacturing to unusual, project-specific specifications under our ISO 9001:2015 quality system — we’re glad to work through this one with you directly.
Please Read Before Ordering This Grade
“ASTM A194 Grade 8R” is not a designation we can confidently place, even at the level of identifying a likely alloying element. We have not verified this designation against a current ASTM A194 standard text at the time of writing this page, and any specific figures a search engine or AI tool might suggest for this grade should not be relied upon without your own verification against the actual governing document.
If you are specifying this grade, please send us the ASTM A194 edition and page/table reference, or your project’s material data sheet, along with your inquiry. We will not quote firm composition or mechanical properties until this is confirmed — this protects both your project and our manufacturing accuracy.
