Stainless Steel Bolt Torque Chart

Stainless Steel Bolt Torque Chart - The following torque values are suggested maximums based upon actual lab testing on clean and dry or near dry fasteners. Web values given represent the torque required to induce a tension in the bolt corresponding to approximately 65% of its proof load. To construct a securely assembled joint using bolts or machine screws, the fasteners must be tightened to develop the proper amount of clamping force. Imperial has made a concerted effort to provide accurate information in its catalog and on its web site, however imperial assumes no responsibility for the accuracy of the information. Using lubrication, tightening fasteners with low rpms and without interruptions, applying only light pressure, and avoiding prevailing torque lock nuts Web maximum tightening torques for us bolts. The load will be 90% of the bolt yield strength. Web torque values for a2 or a4 metric stainless steel fasteners. The lubricated values were calculated at 90% of the dry condition test results. Web portland bolt’s torque chart includes approximate torque values for fastener specifications made from carbon steel and alloy steel.

Web ses 75% of the yield strength. This shows torque values in nm for property classes 50, 70 and 80 as shown in the table below. Web torque values stainless steel bolt table chart. Stainless steel fasteners tend to gall, especially with long run downs, prevailing torque fasteners, impact drivers, and lack of lubrication. Web 5)stainless steel fasteners tend to gall while being tightened. * this table is recommended for use as a guide only. The following data tables are designed to be used as general guidance when installing stainless steel fasteners. Remember, you may need to vary these numbers somewhat based on the individual joint or the amount of fastener lubrication. Iling torque fasteners, impact drivers, and lack of lubrication. While all care has been taken with its preparation, no responsibility is accepted for the

Using Lubrication, Tightening Fasteners With Low Rpms And Without Interruptions, Applying Only Light Pressure, And Avoiding Prevailing Torque Lock Nuts

To construct a securely assembled joint using bolts or machine screws, the fasteners must be tightened to develop the proper amount of clamping force. Remember, you may need to vary these numbers somewhat based on the individual joint or the amount of fastener lubrication. Web maximum tightening torques for us bolts. Bolts and nuts are new, standard finish, uncoated and not lubricated*.

Because Of These Existing Variables, The Only Way To Determine The Correct Torque Is Through Experimentation Under Actual Joint And Assembly Conditions.

* this table is recommended for use as a guide only. The prevailing torque lock nut clamp loads are listed at 75% of the proof loads specified for the appropriate grade bolt: Web ses 75% of the yield strength. Stainless steel fasteners tend to gall, especially with long run downs, prevailing torque fasteners, impact drivers, and lack of lubrication.
