What Are the Different Grades of Bolts? | Hunker

The higher the ISO numbers are, the stronger the bolt. A metric bolt designated as ISO class 6.8 roughly corresponds in strength to an SAE Grade 2 bolt. Bolts of ISO class 8.8 and the slightly stronger class 9.8 roughly correspond to an SAE Grade 5 bolt. An ISO Class 10.9 bolt roughly corresponds to an SAE Grade What Are the Different Grades of Bolts? | HunkerThe higher the ISO numbers are, the stronger the bolt. A metric bolt designated as ISO class 6.8 roughly corresponds in strength to an SAE Grade 2 bolt. Bolts of ISO class 8.8 and the slightly stronger class 9.8 roughly correspond to an SAE Grade 5 bolt. An ISO Class 10.9 bolt roughly corresponds to an SAE Grade 8 bolt.WHAT GRADE OF BOLT SHOULD I USE? Marks BoltsMay 26, 2016 · In the metric world (a.k.a. ISO) the most common bolts are marked with an 8.8, 10.9, or 12.9. If there are no head markings at all, they are most likely comparable to the SAE grade 2. The 8.8 is comparable to the SAE Grade 5.

Metric Fastener Grades Explained - Design & Motion

Nov 19, 2013 · How Grades are Designated. Strength Grades for metric fasteners are designated by a symbol comprised of 2 numbers, separated by a decimal. For example, 4.6 and 8.8. The first number represents 1/100 of the nominal tensile strength in N/mm^2. (4.6) 4 x 100 = 400 MPa nom. tensile strength. The second number is a factor that is 10x the ratio between the nominal yield stress and the Metric Bolt Grades and Strength CalculatorMetric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.Imperial & Metric | Fastener ChartsMetric Classes. MPA (N/MM2) L9 -- 180,000 PSI -- HIGH TENSILE. CLASS 12.9 -- 1,200 MPA -- HIGH TENSILE. SAE GRADE 8 -- 150,000 PSI -- HIGH TENSILE. CLASS 10.9 -- 1,034 MPA-- HIGH TENSILE. SAE GRADE 5 -- 120,000 PSI -- HIGH TENSILE. CLASS 8.8 -- 827 MPA-- HIGH TENSILE. STAINLESS CLASS 80 (304--316) -- 116,000 PSI.

High Quality Metric Fasteners that are built to withstand metric fastener grades

Metric Fasteners come in many grades & sizes. Fastener Grade (US) or Class (metric) refers to the mechanical properties of the fastener material. Generally, a higher number indicates a stronger, more hardened (but also more brittle) fastener. Our handy charts can help you find the metric fastener you need for your application.Grades of Bolts - The Home DepotThere are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher the number means the stronger the bolt.Fuller FastenersOperating since 1976.
