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. 1 Pa = 1 N/m2 = 1.4504x10-4 lb/in2 (psi) 15 rows The highest metric class for strength , it exceeds Grade 8. Because there are so many … For the 10.9 bolt, the 9 tells the user that the yield strength of the bolt is approximately 90% of the first number: 1,000 MPa. Thus, the 10.9 bolt has an approximate yield strength of 900 MPa (940 MPa by specification). heremon symbols that are included …

19 rows A-2 Stainless. Tensile Strength : The maximum load in tension ( pulling apart) which a … METRIC BOLT GRADES AND STRENGTH CALCULATOR. Fasteners conforming to the requirements of ISO 898 are used in applications ranging from −50 C to +150 C. - ISO 898 applies to bolts, screws and studs with coarse pitch thread M1.6 to M39 and fine pitch thread M8 X … Bel-Metric : Class 8 (Standard Strength ) - License Plate Fasteners Flange Bolts 10.9 Metric Nuts Metric Washers Allen Head Fasteners Small Wrench JIS Bolts 8.8 Metric Studs Metric Screws Drain Plugs and Gaskets Body Clips .

Ultimate Tensile and Proof loads for metric bolts according ISO 898-1 Mechanical properties of fasteners made of carbon steel and alloy steel - Part 1: Bolts, screws and studs with specified property classes — Coarse thread and fine pitch thread. Metric Nuts - Proof Loads. The strength of standard ISO metric steel bolts , studs and nuts is readily identified by means of a numerical code. Property classes for steel bolts , screws and studs. The hereprised of two numbers separated by a dot. This dot is not a decimal marker but is merely a means of separating the two parts of the code. Jul 23, 2015 Anybody have insight into why the strongest bolt in the SAE classification system is a lower tensile strength than the highest in the Metric classific . In any case, bolts stronger than either standard goes are available, what might be called SAE Grade 12 or Class 14.9 bolts . The metric bolt is 8.8. That is what a normal shop uses.

- Higher property class nuts may replace lower property class nuts in bolt - nut assembly. - For metric thin nuts, property class of thin nuts is designated as 04 and 05. Thin nuts (style 0) have a herepared to regular nuts or high nuts, and are not …
