NTM Range

The Hi-Force NTM manual torque multipliers offer a selection of high-performance solutions for demanding bolting applications, with torque capacities of up to 9,500 Nm and multiplication ratios ranging from 5:1 to 27:1.

Designed to deliver high torque output with minimal operator effort, the range features robust construction for reliable performance in industrial maintenance, heavy equipment servicing and critical bolting operations. Available with different output square drive sizes to suit a variety of fastener requirements, selected models are equipped with an Anti Wind-Up Ratchet (AWUR) mechanism to prevent reverse rotation and minimise the risk of losing applied torque.

Suitable for applications across oil and gas, power generation, mining, construction, transportation and heavy engineering, the NTM range provides a versatile and controlled solution for tightening and loosening large fasteners where high torque is required.

  • Torque capacities up to 9500 Nm
  • Mean torque multiplication accuracy +/-4%
  • Supplied complete with reaction arm
  • Choice of output square drives of ¾ ", 1" and 1½"
  • Robust construction minimises maintenance requirements and ensures long tool life
  • Anti wind-up ratchet on models NTM40, NTM70 and NTM95 contains the reaction forces generated during tightening for safe, easy operation
  • All models are supplied with a cranked reaction arm. NTM13 and NTM27 are also supplied with a straight reaction arm option
  • Suitable for use with the Hi-Force NTW range of manual torque wrenches
