Testing of actual fastener components is recommended to determine appropriate torque values for all critical-use applications. } Online Books & Manuals No special steps are taken to add further lubrication prior to assembly. bolting torque table 3 - use only with a193 b8, cl1 bolts at 540°c - 650°c on uninsulated flanges. Lubricated . (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. For bolting specifications that do not have a published proofload, it is usually calculated at 92% of minimum yield strength. var dt = new Date(); lbs Nm The published torque values do not include the rotational drag of the elastic stop nuts (AN365). bolting torque table 2a - cold service astm a320 grade l7 stud bolts. If you exceed the proofload value when tensioning the bolt, you run the risk of bolt failure. The bolt is stressed up to the proofload value, and if there is no deformation, elongation, or fracture, then the bolt is deemed to have passed.

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. This table is offered as the suggested maximum torque values for threaded products and is only a guide. Excel App. (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ 1 Proofload is the published number that full size headed bolts are tested to. bolts are standard bolts made of steel with undrilled shank. All calculations are for Coarse Thread Series (UNC). 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 … Edit & Download. } In general the proper torque spec is usually around 65-70% of the failure torque rate.
