Is Grade 8 same as a *?

As per the guide below, issued by the exams regulator Ofqual, the numerical system essentially boils down to the following: 9 = High A* grade. 8 = Lower A* or high A. 7 = Lower A grade.

What is Grade 8 material equivalent to?

Grade 8 / Grade G

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. Grade G is roughly equivalent to Grade 8.

Is Class 8.8 the same as Grade 8?

Q: I'm specifying the strength of a metric fastener and need your help. Is Class 8.8 the same as Grade 8? A: The answer is no. Class 8.8 is not the same as Grade 8.

How strong is a Grade 8 bolt?

Grade 8 bolts are designated as a 150 ksi. This means its tensile strength or the resistance it has before it is subject to breaking under tension is equal to 150,000 lbs. per square inch.

Is a 10.9 bolt stronger than Grade 8?

They are very similar. Grade 8 is an SAE designation. 10.9 is a metric designation. But the two systems yield the same holding strength.

The Differences Between Grade 5 & Grade 8 Fasteners Explained!

Is Grade 8 or 8.8 stronger?

Synopsis: The similarity in names is purely coincidental and the Metric Class 8.8 is not as strong as the Inch Grade 8. As you can see from the table below, a metric Class 8.8 is the equivalent of a Grade 5, not a Grade 8.

Is Grade 8 or 12.9 stronger?

Used in high stress environments, grade 12.9 fasteners are the highest class of metric cap screws. Where Grade 8 fasteners have a 150,000 psi tensile strength, 12.9 fasteners have a 180,000 psi tensile strength, making them more durable than the grade 5.

Is Grade 5 harder than Grade 8?

In conclusion, choosing between a grade 8 and grade 5 bolt depends on the application's requirements. If the application involves high-stress and high-vibration conditions or critical components, grade 8 bolts are the preferred choice due to their higher strength and reliability.

Is Grade 9 better than Grade 8?

Grade 9 Bolts

While the typical grade 8 bolt has a tensile strength of 150,000 PSI, a grade 9 bolt has a tensile strength of 180,000PSI. Grade 9 bolts are ideal for heavy-duty applications and are also often used in heavy machinery such as bulldozers.

Is Grade 8 strong?

High strength: With a minimum tensile strength of 150,000 psi, Grade 8 fasteners are much stronger than most other fasteners on the market. This makes them suitable for use in applications where high loads or forces are present.

Is Grade 8 structural?

ASTM A325 bolts are heavy hex structural bolts and used in structural steel connections, while SAE grade 8 bolts are finished hex bolts and typically used in automotive and equipment applications. By nature, an SAE bolt is also a more precision fastener with tighter tolerances than an ASTM bolt.

Is a Grade 8 at GCSE and A *?

The highest grade you can get is a 9, with 1 being the lowest. This system was introduced in 2017, replacing the old GCSE grading system that awarded students letter grades from A* to G. In the current grading system, a score of 9, 8 and 7 are equivalent to an A* and A.

What does Grade 8 mean in the UK?

| Grade 8 is equivalent to a high Grade A. | Grade 9 is equivalent to higher than a Grade A*. These are the top grades. Grade 9 is the highest grade possible, and is awarded to students for exceptional exam performance — if you get one, well done you!

Is Grade 8 good?

Grade 8 is the equivalent of in between grades A* and A. Grade 7 is the equivalent of a grade A. Grade 6 is the equivalent of just above a grade B. Grade 5 is the equivalent of in between grades B and C.

Is Grade 5 bad?

Grade 5 is a 'strong pass' and equivalent to a high C and low B on the old grading system.

Why is 8th grade so hard?

Among them are: Developmental Changes: The adolescent brain is growing and the individual is often developing intellectual, social and emotional characteristics. Physical Development: Eighth grade students are developing physically, sexually and emotionally and are often experiencing quickly changing hormone levels.

Is 10.9 equivalent to Grade 8?

Class 10.9

This is a metric grading similar to the SAE grade 8 classification, which is used in automotive, and structural industries, as well as in high temp applications. Its strength is near the high end of the grade scale, although there are higher grades and strengths for more specialized fasteners.

Is Grade 8 the hardest bolt?

Commercial-grade 8 bolts are the strongest option available. They're made from medium carbon alloy steel and have markings that include six raised dashes. The psi of the bolt is 150,000, meaning that it can withstand great deals of pressure because of the way it was quenched and tempered.

Is Grade 10 bolt better than Grade 8?

No matter the system used, the higher 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.

Do Grade 8 bolts break easily?

Grade 8 has a higher tensile strength and higher yield strength than grade 5 and lower bolts, but that doesn't mean it is good enough for all locations.

What is the strongest bolt?

These grades start at grade 2 and go up to grade 8, which is the strongest SAE American Grade bolt available.
