Refer to the charts to find the ideal tightening torque. Spring Design Apps This page is based on information from http://ourworld.compuserve.com/homepages/MJVanVoorhis/T205.htm. Economics Engineering Come join the discussion about performance, racing, conversions, modifications, troubleshooting and drivetrain. Customer service | info@boltdepot.com 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. 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). Feedback Advertising Tensile Stress = Force / Cross Sectional Area. The size column also includes the thread count. Strength (psi) Grade Identification Marking Compatible Nuts Min. 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. The distance across flats s of the nut is given in the standard ISO 898-2. I'm not a metalurgist or engineer, but as I understand it, the reduced ductility means it's more brittle. This chart helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength and hardness of common grade bolts. for end bolts: d = e1/(3d0) Ultimate Strength 8 x100 = 800MPa. Power Transmission Tech. In addition, we give the material the bolt is made from as well as its hardness range. ASTM A325 bolts are one of the most commonly used fasteners, usually used for structural steel connections in heavy steel structures. They have a proof load of 55000 psi, minimum yield strength of 57000 psi, and a minimum tensile strength of 74000 psi. Your email address will not be published. ALL RIGHTS RESERVED.

Metric Bolt Grades and Strength Calculator: Note: Breaking torque test applies to bolts and screws with thread less than M3 for which no breaking and proof loads are indicated in ISO 898-1, as well as to short bolts and screws with nominal diameters 3 mm to 10 mm which cannot be subjected to a tensile test.
