• Tensile strength is the mechanical property most widely associated with standard threaded fasteners. Metric Fasteners come in variety of strength, the grade ranging from 4.8 to 6.8, 8.8, 10.9 and 12.9. Let's discuss the strength grades of metric fasteners today. Grade4.8 Tensile strength is 400Mpa. The tensile strength is equivalent to the strength [...]
