How to Use a Torsion Shear Wrenches
1

Place the Bolt

Insert the bolt through the pre-drilled hole.

2

Position the Wrench

Fit the electric shear wrench onto the bolt.

3

Start Tightening

Press the trigger to begin. The wrench will automatically tighten and shear off the spline once the proper tension is achieved.

4

Move to the Next Bolt

After the bolt is correctly tensioned and the spline is sheared off, move on to the next bolt for efficient workflow.

FAQ

 

Q: What is a torsion shear wrench?

A: A torsion shear wrench is a power-driven (pneumatic, electric, or hydraulic) or manual tool used to install torsion shear bolts. Its core function is to apply controlled torque to the bolt’s "torsion section" (a weakened part of the bolt shank) until the section shears off, ensuring the bolt is tightened to the specified preload (clamping force) without over-tightening.

Q: What is the working principle of a torsion shear wrench?

A: Torsion shear bolts have a dedicated torsion section with reduced diameter. When the wrench clamps the bolt’s hexagonal head (or spline) and rotates it, torque is transmitted to the torsion section. Once the torque reaches the bolt’s designed "shear torque value," the torsion section breaks. This shear action signals that the bolt has achieved the required preload, completing the tightening process.

Q: What types of torsion shear wrenches are available?

A: Pneumatic torsion shear wrenches: Driven by compressed air, suitable for high-volume industrial applications (e.g., steel structure assembly) due to fast speed and low heat generation.
Electric torsion shear wrenches: Powered by AC/DC electricity, offering portability and consistent torque; ideal for indoor or areas without compressed air.
Manual torsion shear wrenches: Operated by hand (via a lever or ratchet), used for small-scale, low-frequency tasks or tight spaces where power tools cannot reach.

Q: Do torsion shear wrenches require calibration? How often?

A: Yes, calibration is mandatory—Uncalibrated wrenches may apply incorrect torque, leading to bolt failure or structural risks. Calibrate every 3–6 months or after 5,000–10,000 tightening cycles.

Q: What safety precautions should be taken when using a torsion shear wrench?

A: Use safety glasses (to prevent flying shear fragments), gloves (anti-slip/anti-cut), and ear protection (for pneumatic/electric wrenches with high noise). Check for loose parts, damaged cables/hoses, and worn clamping jaws; do not use faulty tools. Ensure the bolt and connected structure are stable (no movement during tightening).
