WebAn example using a hex bolt with property class 10.9. The Nominal tensile strength of a 10.9 bolt is calculated 10 x 100 = 1,000 N/mm2 (MPa) The Yield stress ratio 9 x 10 = 90%; The Yield stress is therefore 90% of 1,000 = 900 N/mm2 (MPa) Bolts and Studs can be supplied in Property classes Webcommon type (>90% of commercial fasteners). The steel groups and strength classes are designated by a four-digit sequence of letters and numbers (eg A2-70) as shown in the following table. DIN EN ISO 3506 governs screws and nuts made from stainless steel. Steel group Steel grade Strength class Screws. Nuts and Bolts Tensile strength N/mm2 ...

Grade Fastenal
WebIt is comparable in strength to grade 2 materials, yet slightly weaker and easy to weld. This grade is always metric. The ASTM denotation for very similar grade is 304. The corrosion resistance and ease of fabrication are why this grade is used in food industry machines, appliances, architectural trim and aquatic fasteners. Webscenario, the bolt threads will shear out the nut threads. The failure will occur at the root of the nut threads. 3. The nut and bolt are the same strength. In this scenario, both threads will strip simultaneously. This failure will occur at the pitch line. The tensile strength of most fasteners is usually specified, whereas shear strength is not.
