Is a 10.9 Bolt stronger than Grade 8?
A tempered medium carbon steel.
Class 10.9 is stronger than class 8.8.
It is commonly found in high strength automotive applications.
Class 10.9 is similar to grade 8..
Is a 12.9 Bolt stronger than Grade 8?
Many fasteners (screws, etc.), especially smaller sizes, are typically not graded—their strength isn’t specified….Table 1.Grade/ClassStrengthMetric Class 8.8Similar to Grade 5.Metric Class 10.9Similar to Grade 8.Metric Class 12.9The highest metric class for strength, it exceeds Grade 8.11 more rows
What does 10.9 mean on a bolt?
The grade 8.8 refers to the tensile strength which is generally 116,000 psi, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi.
Are Grade 8 bolts brittle?
A Grade 8 has a very high tensile strength, but can be brittle. In applications such as suspensions, a very high number of load/unload cycles can produce work hardening, which produces an immediate, or catastrophic failure.
What is the tensile strength of a 10.9 bolt?
900 MPaFor 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). Two other common symbols that are included on metric parts are the “S” and the 3 designations.
How hard is a 10.9 bolt?
Used in automotive applications and for bolting large and forged parts, metric 10.9 bolts exhibit high tensile strength and good wear resistance. Our metric grade 10.9 bolts meet ASTM A324 grade BD and SAE J429, grade 8 standards. The yield strength of the bolts is 940 and the tensile strength is 1040 MPa.
What is a 12.9 grade bolts?
The minimum ultimate tensile strength of the Grade 12.9 Metric Hex Head Bolts is about 1242 Mpa or 180,000 PSI, making them the highest grade of bolts produced.In fact, the Grade 12.9 Nuts is known for their high tensile strength.
Are 8.8 bolts high tensile?
Grade 8.8 high tensile steel is often referred to as the structural grade for bolts. It is the most common form of high tensile material and is usually stocked in plain finish or zinc. It can be plated in many other coatings.
What is the tensile strength of a Grade 5 bolt?

What is the difference between a 10.9 and 12.9 Bolt?
12.9 grade steel has 120% of the tensile strength of 10.9 grade steel. The “12” prefix indicates a tensile strength of X100 N/mm^2 and the “9” suffix indicates a multiplier. Both 12.9 and 10.9 have the same multiplier, so the comparison is straightforward: 12 to 10.
What is the hardest bolt you can buy?
BUMAX® Ultra has proven itself as the world’s strongest bolt – in various highly-demanding critical fastener applications around the world where standard fasteners are simply inadequate.
What is the strongest bolt grade?
grade 8The strongest commercial-quality bolt is grade 8, marked by six raised dashes; its medium-carbon alloy steel has been quenched and tempered to achieve a tensile strength of 150,000 psi.
What grade are Home Depot bolts?
It’s virtually identical in terms of chemical and physical strengths and properties as an SAE Grade 5 bolt. No matter the types of bolts you need for your home or mechanical project, The Home Depot has the bolts, washers and nuts you need for a secure fit.
What size is a 10.9 bolt?
Metric hex bolts, Zinc plated class 10.9 steel, 10mm x 1.5mm x 70mm.
