ASTM A194
Grade 8RA
Specialty Nuts
An Honest Starting Point on This Grade
Grade 8RA sits directly alongside our Grade 8R page as its presumed strain-hardened counterpart. Across our site, a trailing “A” following an established base grade consistently signals a cold-worked, strain-hardened condition — that’s the pattern behind Grade 8A, 8MA, 8NA, 8PA, and several others, and it’s a reasonable inference to extend here.
But that inference only tells us about the condition, not the base composition — and on the base composition, we carry forward the identical uncertainty from our Grade 8R page. We don’t have a confident basis for identifying which alloying element “R” refers to, so we can’t responsibly state what mechanical property improvement the strain-hardening would even be building on top of.
If your project specification calls out Grade 8RA specifically, we’re genuinely glad to manufacture to it — we simply need the governing ASTM A194 text or your project data sheet in hand first, so we’re confirming a real specification rather than guessing at one.
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 8RA” is not a designation we can confidently place, beyond inferring a likely strain-hardened condition from the trailing “A.” We have not verified this designation, or its base grade Grade 8R, against a current ASTM A194 standard text at the time of writing this page. 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.
Our Process for Genuinely Uncertain Designations
You Share the Governing Document
ASTM A194 edition, project data sheet, or existing mill certificate referencing this exact grade.
We Confirm What the Base Grade Actually Is
We cross-check both Grade 8R and Grade 8RA before verifying composition or manufacturability.
We Verify Manufacturability & Lead Time
Specialty compositions may require raw material sourcing lead time — we’re upfront about this.
We Manufacture & Test to the Confirmed Spec
Full mechanical and chemical verification against your governing document, not general description.
