What is the highest tensile bolt?

What is the highest tensile bolt?

High tensile steel bolts 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 makes a bolt high tensile?

In layman’s terms, the tensile strength of a bolt refers to the maximum stress the bolt can withstand before breaking. Thus, the higher the tensile strength, the higher the weight a bolt can sustain and the higher its capacity to bear impact. High tensile bolts are used for high-stress fastening applications.

How can you tell if a bolt is high tensile?

They both use numbers to grade their bolts – the higher the number, the higher the tensile strength. For instance, the SAE system covers diameters of up to 1 ½ inch, and a grade 8 would have a higher tensile strength than a grade 5. Let’s take a look at the markings you would find on some of the most common SAE bolts.

What does 4.8 mean on a bolt?

Metric steel bolts, screws and studs – proof and tensile strength.

What does 12.9 on a bolt head mean?

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 class 10.9 the same as 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 does 8.8 mean on a bolt?

So, in English, a Property Class 8.8 bolt is a bolt with a nominal tensile strength of 800 MPa and a nominal yield strength that is 80% of that nominal tensile strength, so 640 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.
