FAQs

What is a shear bolt torque limiter?
A shear bolt torque limiter is a device designed to automatically disengage or "shear" when a predetermined torque level is reached, preventing over-tightening and ensuring bolt integrity in critical applications.

How do I calibrate the SB Shear Bolt Torque Limiter?
Calibration should be performed annually or after 5,000 cycles using a certified torque calibration machine, following the manufacturer's guidelines to maintain accuracy and compliance with ISO standards.

Can it be used with all bolt sizes?
The SB Shear Bolt Torque Limiter is compatible with bolts ranging from M8 to M24, but adapters are available for smaller or larger sizes to extend versatility.

What maintenance is required?
Regular cleaning after use, lubrication of moving parts every 500 cycles, and storage in a dry, temperature-controlled environment are recommended to ensure longevity and performance.

Is it suitable for high-temperature environments?
Yes, it operates effectively in temperatures from -20°C to 80°C, but prolonged exposure beyond this range may affect accuracy and component life.
