Frequently Asked Questions (FAQ)

A: Absolutely. We offer customization for handle length within certain limits. Contact our sales team to discuss your specific needs. Minimum order quantities may apply. -
Q: What is the maximum torque the wrench can handle?
A: The maximum torque depends on the specific application and fastener condition. Typically, the 280mm handle design can deliver up to 150-200 Nm of torque for tightening, and the lock mechanism holds securely under high load. For exact data, please request our technical datasheet. -
