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 strengthHigh 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.

Some metric fasteners are available in different strength grades, which is referred to as "property class" or just "class." See Understanding Fastener Grades and Classes for a comparison between metric and inch series strength grades.Understanding Fastener Grades and Classes - Fastener MartThe highest metric class for strength, it exceeds Grade 8. Because there are so many different grades and fasteners all look about the same, medium carbon and alloy steel strength grades are marked for identification. Bolts and screws also bear a mark to identify the manufacturer.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.
