Engineering Highlights

Compact Torque Tightening

High Capacity Range

Lightweight and compact design that provides consistent, reliable torque tightening and shearing for tension control bolts (also known as twist-off or Lejeune bolts).

Capable of achieving a controllable torque range of 5,000 Nm with supported bolt sizes up to M36, optimized for single-operator installation.

Quiet & Efficient Operation

Certified Quality Control

Delivers quiet, non-impacting operation for one-sided installation. Requires no air compressor and no external tool calibration.

Low maintenance tool with electric or manual operation options. All shear wrenches are calibrated and certified at our in-house test bench facility.

One-Sided Installation

Designed for fast, error-free assembly on structural joints where access is restricted to a single side. The outer socket rotates the nut while the inner socket holds the bolt end until shearing off at exact tension.
