The prevailing torque in prevailing torque locknuts comes from localized plastic deformation to an interference fit with continuous sliding during assembly. Let's break this down. Localized plastic deformation - Some of the starting threads need to be able to accept the mating part (bolt, say) before the prevailing torque begins. The interference is therefore localized to not include the ...Read More

In addition to inspections common to all internally threaded fasteners (nuts), prevailing torque locknuts are inspected for prevailing torque performance. Prevailing torque is the resistance to assembling or disassembling the locknut and mating part when the assembly is not clamping (not developing tension in the mating part)...Read More
