By : conttrapacbu23.soup.io. In general the proper torque spec is usually around 65-70% of the failure torque rate. Testing of actual fastener components is recommended to determine appropriate torque values for all critical-use applications. Advertising Center Edit & Download. at 100% of yield. TORQUE-TENSION RELATIONSHIP FOR A307A, GRADE 5, 8 & 9 BOLTS Locknut Size Threads per inch Steel Hex Locknut Steel Hex Flange Nut Grade C FNL Grade 9 Grade F Grade G Clamp Load (lbs.) Title: Metric Bolts, Screws & Nuts: Tightening Torques Author: Fastener Mart Created Date: 8/12/2006 10:22:23 PM Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. Lubricating the bolts is the suggested method. The following points should be considered prior to installation of any fastener requiring torque. // -->, GD&T Training Geometric Dimensioning Tolerancing. No special steps are taken to add further lubrication prior to assembly. } Disclaimer } 2 Clampload is calculated at 75% of proofload. 7/16" - 20 25/64 .3906 80 60 . Torque-Force Calculator | Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. Due to many variables that affect the torque-tension relationship like human error, surface texture, and lubrication the only way to determine the correct torque is through experimentation under actual joint and assembly conditions. (a) bolts and nuts are new, standard finish, uncoated and not lubricated* (b) the load will be 90% of the bolt yield strength (c) the coefficient of friction (µ) is 0.14 (d) the final tightening sequence is achieved smoothly and slowly, until the torque tool indicates full torque has been obtained. The below estimated torque calculations are only offered as a guide. Grade 8 Bolt Drill & Torque Chart in foot pounds . This information is voluntary, and is intended only for general-purpose reference as explained in this disclaimer. document.write(''); Engineering Book Store Proper torque spec varies depending on the material, bolt grade or wether lubrication is used such as oil, wax, or anti-seize Always go to the manufacturer for proper torque specs … The ASTM A307 is an ASTM International standard for carbon steel bolts and studs ranging from 1/4 inches through 4 inches in diameter which is set by the standards organization ASTM International. ** Torque values for 1/4" and 5/16" sizes are in inch lb. Engineering Forum 1/4" - 20 #7 .201 12 9 . This is done to allow a safety buffer so that the bolt does not get too close to the proofload value. ASTM A193 Grade B7 Torque Chart. If you are planning on installing a wheel on your vehicle, it is important to be aware of the manufacturer recommended torque settings. Clamp loads for Grade C lock nuts equal 75% of the bolt proof loads specified for SAE J-429 Grade 8, and ASTM A-354 Grade BD bolts. })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); Maximum Recommended Tightening Torques Metric Course Pitch Grade 12.9 Plated Metric Course Pitch Grade 10.9 Plated Metric Course Pitch Grade 8.8 Plated Nm ft … IFI-100 does not govern lock nuts above 1". There are many variables affecting the torque-tension relationship, such as human error, surface texture, and lubrication. bolts are standard bolts made of steel with undrilled shank. bolting torque table 3 - use only with a193 b8, cl1 bolts at 540°c - 650°c on uninsulated flanges.
