What is class 12.9 Steel?
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 is a Grade A nut?
Grade A Nuts. Strength exceeds Grade 2. ASTM A325. Bolts meet ASTM A325 Type 1 standards for structural steel joints.
Is grade C the same as Grade 8?
Grade C. Grade C is a thru-hardened medium carbon zinc plated alloy steel. No head markings (manufacturers mark may also be included). Finish is equivalent in strength to Grade 8 but without the yellow color.
Is Grade 8 or 10.9 stronger?
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 Bolt is stronger than Grade 8?
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 won’t need anything more than a grade 8 bolt strength or metric class 10.9.
What is the grade for 6 out of 8?

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.
What grade Bolt is the strongest?
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 is a Grade 8 nut?
Hex Nuts—Grade 8. These nuts are about 25% stronger than medium-strength steel nuts.
What kind of steel is Grade 8?
carbon alloy steelGrade 8 bolts are medium carbon alloy steel, quenched and tempered at a minimum temperature of 800 degrees Fahrenheit. They are then heat-treated to achieve a hardness of 33 to 39 on the Rockwell C scale.
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.
Are stainless steel 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.
Are all Grade 8 bolts the same?
SAE Grade 8 is roughly equivalent to a metric Class 10.9. SAE Grade 8 bolts are typically about as strong as you can or want to get. They are the typically gold colored bolts. A metric Class 8.8 is roughly the same as a SAE grade 5.
What is a Grade 5 Nut?
Grade 5 Nut Properties A six sided internally threaded fastener made from steel. Appication. & Advantaged. For use with bolts of a minimum tensile strength equal to or less than the specified proof stress of the nut. Material.
