Grade 8 bolt strength chart

x2 The chart below summarizes some of the more common grades and classes available here at Fastener Mart. Table 1. Common fastener grades and property classes. Strength exceeds Grade 2. Bolts meet ASTM A325 Type 1 standards for structural steel joints. Strength is similar to Grade 5. Same as Grade 5. This means the tensile strength is 120,000 lbs per square inch. It also lists Grade 8's as 150 ksi fasteners meaning the tensile strength is 150,000 lbs per square inch. Also, the ultimate shear strength of a fastener is typically about 60% of its ultimate tension strength.These metric bolt torque charts show the ideal tightening torque for class 8.8, 10.9, and 12.9 bolts for both wet and dry tightening. The bolt's class indicates its material strength, with higher numbers meaning higher tensile and yield strength.

Grade 8 Medium carbon alloy steel, quenched and tempered: 1/4" thru 1-1/2" 120,000: 130,000: 150,000: Grade A325 Carbon or alloy steel with or without boron: 1/2" thru 1-1/2" 85,000: 92,000: 120,000: Stainless Markings Vary: 18-8 & 316 Stainless Steel alloy with chromium and nickel: All sizes thru 1" N/A: 20,000 Min. 65,000 Typical Grade 8.8 Bolt is a high strength fastener that is used for structural applications. The material has good strength corrosion resistance and good wear and tear resistance properties. The standard specification for these bolts is the ASTM A324. The High Tensile Grade 8.8 Bolts come in dimensions ranging from ¾ inches to 3 ½ inches in diameter ...

The two figures indicate the tensile and yield strengths of the bolt or screw. In the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. The second figure signifies that the fastener will begin to yield at 80% of the Ultimate Tensile Strength, i.e. at least 640MPa.To get pounds force, you need to multiply the shear strength by the shear area. Your equation implies you divided by the shear area. 2. The formula for the area of a circle is A = Pi * R^2, where R is the radius. The radius of a 5/8 diameter bolt is 5/16 inch. Therefore the equation should be: 91000*Pi* (5/16)^2 = 27000 pounds force.Medium-Strength Metric Class 8.8Steel Square-Neck Carriage Bolts. Choose these metric bolts for fastening most machinery and equipment. They are twice as strong as low-strength steel bolts. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut. However, as you can see in the following table, both tension and shear are higher in Grade 8 bolts over Grade 5 bolts; in fact over 21% higher in shear and 25% in tension. The same is true in metric when comparing 8.8 vs 10.9. To be fair, the higher the grade of bolt, the harder it becomes as rated by the rockwell scale.Medium-Strength Metric Class 8.8Steel Square-Neck Carriage Bolts.
