Grade 10.9 bolts are typically used in automotive applications and for bolting large, forged parts and are often made using carbon steel and boron steel. Socket and Countersunk buttons are commonly manufactured in this grade. Grade 12.9 bolts, fasteners and fixings are for some of the heaviest jobs, such as securing engines and ensuring that drives are tamper proof.

For example, in an application where the load results in a maximum stress of 900 MPa, a Grade 10.9 bolt may suffice to avoid failure in service, however the conservative approach would be to provide a generous factor of safety and select a Grade 12.9; this can often prove catastrophic.FASTENER REFERENCE GUIDEGrade 8.2 Medium carbon boron steel quenched & tempered 1 4 - 1 120,000 150,000 C33 C39 130,000 SAE J995 Grade 8 Hex FNL Grade 9 Medium carbon alloy steel quenched & tempered 1 4 - 1-1 2 140,650 180,000 C38 C42 159,500 FNL Grade 9 Thick Hex Nut ASTM A574 Socket Head Cap Screw Medium carbon alloy steel quenched & temperedGrades of Bolts - The Home DepotThe 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 to grade the bolts, the higher the number means the stronger the bolt. For most home and automotive applications, you wont need anything more than a grade 8 bolt strength or metric class 10.9.

Metric Class 12.9 The 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 grade 10 9 12 9 high strength carbon steel tire bolt and nutWhat Are the Different Grades of Bolts? HunkerA grade 2 bolt made of low-carbon steel has a tensile strength of 64,000 pounds per square inch or less. Tensile strength is the amount of pull the bolt can withstand before breaking. A bolt head with three raised dashes in a radial pattern marks an SAE grade 5 bolt of tempered medium carbon steel with a tensile strength of at least 105,000 grade 10 9 12 9 high strength carbon steel tire bolt and nut

Which is stronger 12.9 or 10.9 steel? - Quora

Aug 30, 2018 · I have no experience with this. I regularly use bolts at work, but we do not require any knowledge of a tensile strength (to a certain extent). This should explain it, I'm guessing the larger the number, the greater the tensile strength. I'd recom grade 10 9 12 9 high strength carbon steel tire bolt and nut
