Show that the Strain Energy is increased when the bolt is under maximum Stress, if the shank of the Bolt is turned down to the root diameter of the thread. Metric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4. Space them at 16" centers near the interior of the wall to leave room for the hold-down bolts at the ends. 2) To carry out the analysis of bolted joint with different clearance in between the bolt shank and hole on the plate. Re: how to calculate PSI to Nm for torque 12/07/2008 12:30 PM Although I've been rightfully humbled to realize that the fugacious guest may not have been writing of things bolted when he fleetingly came upon the site, I've been able to work it out so that the spreadsheet which I wrote of can now be available. This publication was supported by ASHRAE Research Project RP-1616 and was prepared under the auspices of TC 4. Capacity of high-strength steel bolt calculator AN BOLT SELECTOR Hex head aircraft bolts are made of high-strength type 4037 or 8740 alloy steel (type 8740 is most commonly used). Ultimate Tensile Stress is a "threshold" stress; if the applied load per unit area always remains below this threshold value, then the material will not fail.
