Grade 8 vs. A325 - Structural engineering general ...May 09, 2005 · I think that a Grade 8 bolt is equivalent to an A490 in strength, but I don't have these specs at home today. Another difference is that stuctural bolts have a larger head size so the A325 would be bigger than the Grade 8. Also thread length can be different which could result in threads being in the shear plane.

No. The strength properties of SAE J429 grade 5 bolts and ASTM A325 bolts are identical; likewise, SAE J429 grade 8 bolts are the strength equivalent of ASTM A490 bolts. These material specifications differ, however, in that ASTM A325 and A490 specify thread length and head size, whereas SAE J429 does not.

Metric Class 4: Similar to Using High Strength Bolts for Structural Bolting | The grade 8 vs a325 structural engineering generalJun 05, 2020 · Grade 8 Bolts. A grade 8 bolt is the highest grade SAE bolt. Grade 8 bolts have a minimum tensile strength of 150,000 PSI. As a comparison, the ASTM A325 bolt is roughly equivalent to the SAE grade 5. A grade 8 bolt would be one that meets ASTM A490 standards. The A325 bolt strength, or SAE grade 5 bolt strength, is usually used for structural bolting projects.What Are the Different Grades of Bolts? | HunkerIts strength grades are indicated by the letter A plus three numerals stamped on the bolt head. Common ASTM grades include A307, which roughly corresponds to SAE Grade 2. An ASTM A325 bolt is roughly equivalent in strength to SAE Grade 5 and an A490 bolt is about equivalent in strength to SAE Grade 8.

What Is the Difference Between Plain Grade 8 Bolt &

A common fastener is made from steel, varying by different grades. Grade 2 steel is the most affordable, while Grade 8 is heavily reinforced but has a higher cost.
