MANTIS Precision Torque Locknuts

Swift, exact installation the first time, every time

Many applications requiring a torqued locknut lead to a repetitive and inefficient installation process: torque, try to pin, adjust, try to pin, repeat. However, even very minor changes of rotation of the nut will make very significant changes in the preload force. Other scenarios result in unknown final torque value or require installers to replace and re-install to try to reach specified torque ranges. 

Sky Climber Fasteners’ MANTIS Torque Nut allows installers to set to mid torque value and pin immediately. The result is a precise torque value 100% of the time with no deviation from the desired preload in the fastened joint.
