ASTM A193/A193M B8 and B8M Class 1 Torque-Tension Guide
www.fastenal.comThe torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. UN8 Thread Series Caution: Stainless steel fasteners tend to gall, especially with long run downs, prevailing torque fasteners, impact drivers, and lack of lubrication.

Pocket Guide to Tightening Technique - Atlas Copco
www.atlascopco.com7. TORQUE AND ANGLE As mentioned above, the tightening torque is for practical reasons the criteria normally used to specify the pre-stress in the screw. The torque, or the moment of force, can be measured either dynamically, when the screw is tightened, or statically, by checking the torque with a torque wrench after tightening.
SELF-LOCKING FASTENERS - PennEngineering
www.pemnet.comAll PEM metal prevailing torque type locknuts achieve their prevailing torque by altering the shape of the nut in some way - most commonly by distorting the threads of the nut, which then grips the mating part during tightening. Screws for use with PEM prevailing torque locknuts should be Class 3A/4h fit or no smaller than Class 2A/6g.
MINIATURE SELF-CLINCHING FASTENERS - PennEngineering
www.pemnet.comPrevailing torque locknuts provide essentially the same torque value regardless of the amount of axial load applied. Their use can save time and money compared with alternative chemical locking methods or patches. A dry-film lubricant applied to locking FE™/FEO™/UL™ nuts provides the smooth, non-galling prevailing torque performance
