Mechanical Torque

Manual Torque
Multipliers

ToughTorq manual torque multipliers use planetary gearing to increase operator input torque for large fasteners and high-output bolting. Z Type models prioritize compact confined-space use, while L Type models provide offset geometry for applications where access and reaction clearance are limited.

Mechanical Advantage

High torque without external power

Planetary gearing increases operator input torque to produce controlled high-output torque for large fasteners. Selection is based on the required output torque, multiplier ratio, square-drive sizes, fastener range, reaction point, and working clearance.

✓

Planetary gear train multiplies torque output

✓

Manual operation without hydraulic, pneumatic, or electric power

✓

Adjustable reaction foot for application flexibility

✓

Designed for large-diameter bolts and nuts

✓

Z Type models suit confined-space applications

✓

L Type models provide offset access

✓

Custom configurations available for application requirements
