How strong is a grade 10.9 bolt?
The yield strength of the Class 10.9 Bolt is 940 Mpa and the tensile strength of the Grade 10.9 Nuts is 1040 MPa..
What is a Class 8.8 bolt?
Metric Bolt Grades. Class 8.8. Head Marking: 8.8. Material: Medium carbon steel, quenched and tempered.
What does 12.9 mean on a bolt?
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.
Is there a grade 10 bolt?
Class 10. This is a metric nut grading similar to the SAE grade 8 classification, which is used in conjunction with Class 10.9 bolts. This strength of nut is used in automotive, and structural industries, as well as in high temp applications.

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 difference between 8.8 and 12.9 grade bolts?
The mechanical difference between the 12.9 and 8.8 is yield strength (roughly 90% of 1200 MPa vs 80% of 800 MPa). That means the 12.9 can be stretched further (i.e. torqued to some higher value) before it yields, which of course increases the clamp force.
How can you tell if a bolt is high tensile?
To identify this grade, look out for an ‘8.8’ stamp or a set of three radial lines on the head of the bolt. Most often, customers looking for a high tensile bolt may just be looking for the 8.8 grade.
What grade are ARP bolts?
Explains how ARP polished stainless steel and black oxide finished 8740 bolts are stronger than SAE Grade 5 or Grade 8 fasteners, as well as ISO 8.8 and 10.9 rated metric bolts. ARP accessory bolts are nominally rated at 170,000 psi tensile strength, far superior to the 120,000 of Grade 5 and 150,000 Grade 8 ratings.
What is the hardest grade bolt?
The 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.
Are Grade 8 bolts hardened?
Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head.
What grade bolt has the highest shear strength?
They are commonly used at high stress points in connecting devices.12.9 Bolts. A 12.9 bolt is one of the highest grade of bolts produced. … 12.9 Shear Strength. The minimum tensile strength of a 12.9 bolt is 1220 MPa.
Is a 10.9 Bolt stronger than Grade 8?
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. A low carbon steel for general use.
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.
Are stainless bolts stronger than Grade 8?
Stainless steel bolts are rated for corrosion resistance. Bolt strength is rated in PSI (pounds per square inch). A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI). A grade 8 bolt has a stronger rating with a PSI of 150,000.
