Grades of Bolts - The Home Depot

The most common grading system used for bolts in the U.S. is the SAE system, but you can find metric grading systems as well. There 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 metric fastener gradesHigh Quality Metric Fasteners that are built to withstand metric fastener gradesGrades & Sizes. 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.

About Thread Galling.Fasteners | Bolt Grades, Strength & MaterialsZinc Plated Alloy Steel is a common material that fasteners are manufactured in. Zinc plating creates corrosion resistance and gives the bolts a shiny finish. Zinc plated alloy steel is most often available in Grade A, Grade C, Grade 2, Grade 5 and Grade 8. Untreated alloy steel fasteners are black. Bolt Grades & Head Markings:How to Read Metric Bolts | SciencingMany metric bolts denote the use of metric measurements with an "M" at the start of the bolt designation, such as "M9x1.2x15." Metric bolts list measurements in millimeters. Besides using metric measurements, a metric bolt uses the distance between the threads rather than the thread pitch, used in American measurements, which is the number of metric fastener grades

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 8 bolt.ASTM, SAE and ISO Grade Markings for Steel Fasteners metric fastener gradesDownload a complimentary PDF of our Fastener Markings chart.

Metric Fastener Grades Explained - Design & Motion

Nov 19, 2013 · 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 strengthMetric Steel Bolts - Grades and Property ClassesSteel Bolts - SAE Grades For metric bolts strength is according ISO 898 Mechanical properties of fasteners made of carbon steel and alloy steel described by "property classes" with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.Metric System & Specifications | FastenalFastener Property Classes The metric system designates strength capabilities via property classes rather than grades. The numbering system is very simple; the number that appears before the decimal, when multiplied by 100, will provide the approximate minimum tensile strength of the bolt.

Strength Requirements by Grades - Packer Fastener

Strength Requirements by Grades. Yield strength, or working load limit, is the amount of stress a material can withstand without permanent deformation.. Tensile strength is the maximum amount of axial stress that a material can take before breaking.. All strength measurements are in ksi (kilo-pound per square inch). To find the actual weight a bolt can withstand you would have to multiply by metric fastener gradesUnderstanding Fastener Grades and Classes - Fastener Mart15 rows · The highest metric class for strength, it exceeds Grade 8. Because there are so many What Are the Different Grades of Bolts? | HunkerMetric Grades. The strength grade of a metric bolt, known as its property class, consists of two numbers separated by a dot. The property class is expressed in raised or depressed numerals on top or on the side of the bolt head, according to rules set by the International Standards Organization.
