Fastener Locking Torque Prevailing Torque Tester

Servo torque bench that turns lock nuts and self-locking screws on and off a test bolt and records prevailing torque in each cycle. Used by automotive fastener makers and assembly plants for locking performance checks.

Specification

A lock nut is turned on and off a test bolt by a servo drive while torque is captured in each cycle. The first on and fifth off values are reported against specification for nylon-insert and all-metal prevailing torque nuts.

Features

• Servo drive with programmed number of cycles
• Inline reaction torque sensor with peak capture
• Multiple test bolt sizes M6 to M20
• Graph of torque against angle on screen
• Safety door with interlock
