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 grade 8.8 bolt?
8.8- This type of grade is often referred to as the structural grade for bolts. These types of bolts often have galvanised hexagon heads, and most are made with zinc or are zinc plated. … This grading, which is typically stamped on the head of the bolt, has the same tensile strength as a grade 8.8 bolt.
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.
How much weight can a 8.8 Bolt hold?
Consequently, how much weight will a bolt hold? bolt could hold 70,000 x 3.14 x (0.3^2)/4 = ~5000 lbs. How much weight can a 8.8 Bolt hold? For example, a grade 8.8 bolt will not snap until every square metre of the bolt cross section is carrying a load of atleast 80kg per square millimetre.

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.
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 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.
How strong is a grade 12.9 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.
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.
Are higher grade bolts more brittle?
One common misconception about bolts is that a higher rated bolt is stronger, yet more brittle, and therefore lower grades should be used in places like in suspension systems so they can deform rather then break. This is wrong! There are two types of forces a bolt experiences, tension and shear.
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 titanium bolts stronger than steel?
Titanium bolts can be as strong as mild steel or stainless steel bolts. Titanium bolts are not as strong as high-tensile steel bolts.
Is b7 stronger than Grade 8?
With a minimum tensile strength of 150 ksi and a minimum yield of 130 ksi, Grade 8 has a higher tensile and yield strength than other steel grades such as Grade 5 and B7. It is also quenched and tempered at 800 F leading to its strength. … The preload or thread tension in a fastener is higher with Grade 8 quality steel.
How much weight can a Grade 5 bolt hold?

What Bolt is stronger than Grade 8?
Grade 8 / Grade G 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. Grade G is roughly equivalent to Grade 8. Grade G nuts are used with Grade 8 bolts.
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.
Will Grade 8 bolts rust?
Grade 8 bolts have 6 evenly spaced radial lines on the head.” Unlike stainless steel, which is highly resistant to corrosion, steel, however reinforced, will oxidize over time and rust. Grade 8 bolts that are not galvanized or plated with yellow zinc, however, are cheaper.
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.
What grade bolt means?
The grade of a bolt determines the maximum amount of stress (tensile strength) that the bolt can handle. Tensile strength is the amount of pull the bolt can withstand before breaking. The method used for tightening the bolt is also dependent upon the grade of the bolt.
