Torque Value
(OP)
How would one go about determining the torque value of a jam nut. It is 1"-12tpi. The application is a 1-12 threaded rod with a jam nut to lock it. It is under static load of about 12000lbs. Thanks for any info, VSH





RE: Torque Value
what strength rod are you talking about,
equivalent to grade 5 or grade 8.
If grade 5, you are looking at torque values of
640 ft-lbs dry or 480 ft-lbs lubed.
If grade 8, 1000 ft-lbs dry or 740 ft-lbs lubed.
