SAE Grade 8 (A5 2465 High Tensile Steel) 150000: 1034: Class 10.9 (A5 1110 High Tensile Steel) Stainless Steel Class 100: 1000: Stainless Steel Class 100 (e.g. Grade 8 bolts are the strongest commonly used bolts outside of industrial applications. Pressure Vessel Ultimate Strength 8 x100 = 800MPa. The design shear resistance of bolts Fv,Rd as given in EN1993-1-8 Table 3.4 is only valid when the bolt is used in holes with nominal clearance not exceeding the values given in the standard EN 1090-2 'Requirements for the execution of steel structures', as specified in EN1993-1-8 3.6.1(4). Thermodynamics .style4 {color: #339900} Related. Tensile Stress = Force / Cross Sectional Area. Note: Manufacturer's identification mark are also stamped when applicable. For fastening bolts used in different products and All rights reservedDisclaimer | Materials and Specifications Stainless markings vary. Lbs DryPartsK=.2 Material strength for threaded fasteners and headed industrial fasteners from Elgin Fasteners Group is listed below by grade, type and class and separated into 60,000 psi, 75,000 psi and 120,000 psi. Mechanical Tolerances Specs Downloads Grade 2 bolts are used for applications that require fastening but do not require the bolt to undergo heavy load. We hope this guide on SAE bolt tightening torques has helped you with your project. The grade 8.8 can also be defined as the medium carbon steel specification for bolts. Bolts must be tightened using the correct torque. Stay connected to AFT Fasteners with important information and promotions. The flange distributes pressure Medium Carbon Alloy Steel, Quenched and Tempered. ASTM A325 bolts are one of the most commonly used fasteners, usually used for structural steel connections in heavy steel structures. Shear strength is typically estimated to be 60 percent of tensile strength. Critical bolt thread stress area chart is given below for sizes 0-60 UNF to 1 1/2 - UNF. This information is derived from data here. In addition, we give the material the bolt is made from as well as its hardness range. End distance equal to 2 x bolt diameter, Thickness in mm of material passed through, The tensile stress area (At ) is obtained from standards. They show examples of the typical bolt grade markings for each bolt grade. BS449: Part 2 Bolt Grade 4.6, Loading Capacities of Ordinary Bolts per. .style10 {font-weight: bold; font-size: 12px; } Each bolt grade has an ideal tightening torque for maximum clamping force without breaking. I'm not a metalurgist or engineer, but as I understand it, the reduced ductility means it's more brittle. Bumax 109) SAE Grade 5 (A5 2465 High Tensile Steel) 120000: 900: Class 8.8 (A5 1110 High Tensile Steel) 827: Stainless Steel Class 80 (e.g. The most common SAE bolt grades are Grade 2, Grade 5, and Grade 8. Economics Engineering Most stainless is non-magnetic. ALL RIGHTS RESERVED. for inner bolts: d = p1/(3d0) - 1/4. Keep this page bookmarked so that you can quickly refer to it the next time you need to know the best tightening torque for SAE bolt grades 2, 5, and 8. Please select a previously saved calculation file. Mechanical/mkank()l/ operated by a machine or machinery. Very few applications outside of industry require higher than a Grade 8 bolt. Grade 8 fasteners are considered hi-strength / high-tensile fasteners and are used in many highly industrial applications such as machinery, valves, pumps, vessels, motors, tractors, and even tanks Although it may seem like a bolt is a bolt, there are significant differences in how each bolt is manufactured. Lubrication Data Apps Therefore, based on the equations above, the bearing resistance of the bolt Fb,Rd is not affected by the distances e1, p1, e2, p2 when the following conditions are satisfied: for edge bolts: e1 3.0d0 and e2 1.5d0 Threads & Torque Calcs The bolts are color coded at the end that will project from the concrete to easily identify the grade used in the field (Grade 36: Blue, Grade 55: Yellow, Grade 105: Red). There are three grades within this specification, 36, 55, or 105. Electronics Instrumentation LEGAL AND PRIVACY DISCLAIMER. Feedback Advertising Engineering ANSI Hardware Design Data, See Explanatory notes given below table. Structural Shapes Physics Terms and conditions | They are made of medium carbon alloy steel and have 6 line marks on the head. The standard metric bolt diameters are specified in the standard ISO 898-1 Tables 4 and 5. What is the yield strength of Grade 8 bolts? Grade 8 (SAE J429) is a medium carbon alloy steel with one of the highest tensile strengths available. With a minimum tensile strength of 150 ksi and a minimum yield of 130 ksi, Grade 8 has a higher tensile and yield strength than other steel grades such as Grade 5 and B7. Values in italic are greater than the double shear capacity of the bolt. Another good source is here, providing English and Metric values, and pictures of the head-markings for different bolt grades. The carbon steel fasteners have different properties such as pitch, head across flat surface, head height and others. Bearing > Double Shear. , Engineering ISO Metric Hardware Design Data The higher the grade, the stronger the bolt. If oversize or short slotted holes are used, bearing values should be multiplied by 0.7. Bolt Grade Markings & Strength Chart - Metric Steel Bolts, Tensile Strength:The resistance of a material to breaking under tension, Yield Strength: The stress at which a specific amount of deformation is produced. .style8 {color: #00FF00} Free online calculation tools for structural design according to Eurocodes.
