Bolt Grade Markings and Strength Chart
|Head Marking||Grade and Material||Mechanical Properties|
|Min. Tensile Strength (psi)|
|3 Radial Lines||Grade 5 Medium carbon steel, quenched and tempered||120,000|
|6 Radial Lines||Grade 8 Medium carbon alloy steel, quenched and tempered||150,000|
What is tensile strength rating?
Tensile strength specifies the point at which a material goes from elastic to plastic deformation. It is expressed as the minimum tensile stress (force per unit area) needed to split the material apart. The tensile strength for structural steel is 400 megapascals (MPa) and for carbon steel it is 841 MPa.
What is the tensile strength of a Grade 10 bolt?
The High Tensile Grade 10.9 Screw is a special type that does not need nuts to fix it onto other components. This grade of bolts have tensile strength upto 1040 minimum and yield strength up to 940MPa minimum.
What is the tensile strength of Grade 8 steel?
A grade 8 bolt is the highest grade SAE bolt. Grade 8 bolts have a minimum tensile strength of 150,000 PSI.
Is a Grade 5 bolt strong?
Grade 5 bolts are hardened to increase strength and are the most common bolts found in automotive applications. Grade 5 bolts have 3 evenly spaced radial lines on the head. Grade F is roughly equivalent to Grade 5.
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.
Is tensile a strength?
Tensile strength is defined as the “resistance to lengthwise stress, measured by the greatest load in weight per unit area pulling in the direction of length that a given substance can bear without tearing apart” (Webster’s New World Dictionary of the American Language, 1959).
What is tensile strength with example?
Imagine a strip of paper being pulled at its two ends with your fingers. You are applying a tensile force on the strip. When this tensile force crosses a certain threshold, the paper tears. The tensile stress at which this takes place is the tensile strength of that material, in this case paper.
Is a Grade 10 bolt stronger than a Grade 8 bolt?
Each grade has a specific bolt strength. No matter the system used to grade the bolts, 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.
Is 8.8 high tensile?
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.
Is Grade 8 or Grade 5 stronger?
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.
What is the strongest bolt grade?
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.
How to calculate Tensil strength for Grade 2 bolt?
Nominal Dia of Products and Threads per Stress Area. sq. in Grade 2 Grade 5 Grade 8 Proof Load, lb. Tensile Strength Min, lb. Proof Load, lb. Tensile Strength Min, lb. 1/4 – 20 0.0318 1750 3800 4750 5/16 – 18 0.0524 2900 6300 7850
What are the properties of 18 / 8 stainless steel?
Standard 18-8 stainless steel includes SS 304, 304L, 304N, 304LN, 304H, non-standard 18-8 grade includes AISI 301, 302, 301L, 301LN, 302B, etc. 18/8 steel is the most widely used material, has excellent corrosion resistance in mild environments, and has good weldability and mechanical properties.
What is the strength of a Grade 5 proof load?
Grade 5 Grade 8 Proof Load, lb. Tensile Strength Min, lb. Proof Load, lb. Tensile Strength Min, lb. Proof Load, lb.
What’s the difference between yield and tensile strength?
Tensile Strength: The maximum load in tension (pulling apart) which a material can withstand before breaking or fracturing. Yield Strength: The maximum load at which a material exhibits a specific permanent deformation. Proof Load: An axial tensile load which the product must withstand without evidence of any permanent set.
