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.For high tensile steel grade 8.8, a torque wrench will be required for the tightening of said product 827 Class 8.8 (AS 1110) High Tensile or High Strength Steel—Structural AS 1252 SAE Grade 8 (AS 2465( (High Tensile) 150 000 1034 Class 10.9 (AS 1110) High Tensile Conversion Factors 1000 PSI (lbf/in²) = 6.8948 MPa 1 Mpa = 145.038 PSI(lbf/in²) Compare Tensile Strengths of Steel Grades and Class Metric system uses Grades

An 8.8 bolt has an ultimate tensile strength of 80 Kg/mm2 (785N/mm2) and a yield strength of 80% x 80Kg/mm2 = 64 Kg/mm2 (628N/mm2) Surely an allowable shear stress of 70% x ultimate tensile stress is much too high. This 550 N/mm2. Generally, the shear stress is equal to 60% x yield stress. This gives a shear stress of 375 N/mm2 The Class 8.8 Bolts are known as high tensile bolts. These have high torque capacities with high tensile strength ranging above 500MPa. The carbon steel fasteners have different properties such as pitch, head across flat surface, head height and others

The tensile strength can easily be converted between both types of thread pitch by recalling that a Grade 2 bolt possesses the same tensile strength as a Class 4.6 bolt, a Grade 5 bolt possessing the same tensile strength as a Class 8.8 bolt, a Grade 8 bolt possesses the same tensile strength as a Class 10.9 bolt and a Grade 9 bolt possesses. Grade 8 hex cap screws are made to a much higher precision than grade 8 bolts. 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. In comparison, a Grade 5 bolt is weaker as its tensile is 120 ksi, placing it. Ordinary bolts are generally made of ordinary steel (Q235) and only need to be tightened. Ordinary bolts are generally 4.4, 4.8, 5.6 and 8.8. High strength bolts are generally grade 8.8 and grade 10.9, most of which are grade 10.9. The screw hole of ordinary bolt is not necessarily larger than that of high-strength bolt The designation system is based on two numbers e.g 8.8 .

Thus, for the bolt of property class 8,8 in the above example a nut of property class 8 is required. This nut will have a Proof Load Stress of 8 x 100 = 800 MPa In practice only standard threaded fasteners in the high tensile property classes, i.e. property class 8,8 and above are required to be marked with the appropriate code high tensile hex bolts, high tensile bolts price list, manufacturer of high tensile fasteners, high tensile bolts grade, specifications, strength, torque, weight chart, material equivalent, tensile strength, chemical composition, properties, bolt dimensions, diameter, 8.8 bolt lengths, grade 8.8 bolt material specification, weight of grade 8.8. Usually a tensile strength in the range of 112,000 to 116,000 PSI. In the metric world (a.k.a. ISO) the most common bolts are marked with an 8.8, 10.9, or 12.9. If there are no head markings at all, they are most likely comparable to the SAE grade 2. The 8.8 is comparable to the SAE Grade 5. The 10.9 is comparable to the SAE Grade 8 Hi, The likely tensile strength of the bolt is as you say grade 8.8 but your load on the bolt is a shear loading which is different. The weakest point of the bolt is the junction of the shank and the thread but the load on your bolt is on the shank the stronger part of the bolt. With some research that size bolt has a shear capacity of circa. When dealing with metric fasteners, the 8.8 bolts are similar to a Grade 5. If you need higher tensile strength in metric, stick to 10.9 or 12.9. The higher the first number, the stronger the bolt in terms of tensile strength. The higher the second number, the longer it will take to enter the yield point

The first number represents 1 / 100 of the tensile strength, and the second number represents 10 times the ratio of yield to tensile strength. The tensile strength of Grade 8 bolts or grade 8.8 bolts is 800MPa, and the yield strength is 800 x 0.8 = 640mpa. The bearing capacity of the bolt can be calculated by selecting the cross-sectional area. There are also different grades of the High Tensile bolts ranging from 8.8, 10.9, 12.9 and so on. Please feel free to contact us for more information on the high tensile bolts and prices. Din933 High Strength 8.8 4.8 Grade Electric Galvanized Hex Bolt . Brass High Tensile Bolt If you have ever looked a metric hex bolt you might notice the markings 8.8, 10.9 or 12.9 this does not mean grade 8,10 or 12. The grade 8.8 refers to the tensile strength which is generally 116,000 psi, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi

Thus grade 10.9 bolts have an ultimate material tensile strength of 1000N/mm2 and the yield (or proof) stress is 90% of the ultimate strength. Similarly, grade 8.8 bolts have an ultimate strength of 800 N/mm2 and a ratio of yield/proof stress to the ultimate strength of 80% Big bolt nut is the biggest manufacturer for larger diameter high tensile fasteners & nuts in India, we have a monthly production of over 300 tons in bigger sizes from M-24 to M-64 in 8.8 and 10.9 grade. These high tensile fasteners are used in energy sector like wind, solar, thermal and hydro energy Din 933 Half Threaded Hex Bolts ,Steel Hex Bolt M3 - M42 Size Grade 8.8 Products Description: The six angle bolt is a fastener consisting of fingers and screws. The bolts are divided into iron bolts and stainless steel bolts according to the material, namely the six angle head bolts (partial threads) -C and six angle bolts (full thread) -C level You cud also have googled for your query to get many things as below. Now make your judgement. ibro (Structural) (OP) 7 May 05 06:03 We are provider of packaged modular energy solutions and we use A325 bolts for skid steel framing (One skid packag..

High Tensile Steel Grade 8

Hex Bolt Full Thread Grade 4.6 / 8.8 & 10.9. A Hex Bolt is a form of threaded fastener with an external male thread. And bolts are very closely related to screws. These are grade 4.6 and 8.8. The first digit so relates to the ultimate strength of the material. Because the second is the ratio of yield stress to ultimate strength Bolt grade. Bolt Material . Bolt diameter.

They are driven by wrenches or sockets and are ideal for limited-clearance applications. Alloy steel is the strongest of all steel types


For example, a Class 8.8 bolt has a nominal tensile strength of 800 N/mm2 (or about 116,000 psi) and a nominal yield stress of 640 N/mm2 (8 times 800 divided by 10). Being that I'm not much of a math guy (unlike like many of the engineering types on this board ) the simple point to take away might be - SAE Grade 8 (150,000 psi tensile strength. The image above shows hex head markings for 8.8, 10.9, 12.9, and 18.8. These markings are standard on metric size fasteners and refer to the tensile strength. Metric Grade 8.8 Hex Cap Screws. Grade 8.8 fasteners are made from heat treated, medium quality carbon steel Our metric grade 10.9 bolts meet ASTM A324 grade BD and SAE J429, grade 8 standards. The yield strength of the bolts is 940 and the tensile strength is 1040 MPa. How hard is a Class 10.9 bolt? This grade of bolts have tensile strength upto 1040 minimum and yield strength up to 940MPa minimum 6 Radial Lines Grade 8 Medium carbon alloy steel, quenched and tempered 1/4 thru 1-1/2 120,000 130,000 150,000 Class 8.8 Medium carbon steel, quenched and tempered All sizes below 16mm 580 640 800 16mm - 72mm 600 660 830 Class 10.9 Alloy steel,.
