As a professional manufacturer with over two decades of experience, Cangzhou Dean Safety & Special Tools Co., Ltd. proudly introduces our Self-Locking Torque Wrench designed for precise and reliable fastening in critical applications. This wrench covers a torque range of 10–50 Nm with a standard 1/2" drive, and comes complete with a 2-year warranty and an individually issued calibration certificate. Built to meet the demands of automotive, industrial maintenance, and assembly lines, it ensures every bolt is tightened to the exact specification without risk of over-torquing.
Our self-locking mechanism provides an audible and tactile click when the preset torque is reached, preventing accidental movement away from the set value. The ergonomic handle reduces hand fatigue during repeated use, and the clearly laser-etched scale allows fast, error-free adjustment. Backed by our factory’s annual export value exceeding US$100 million and global shipping from Tianjin, Shanghai, and Ningbo ports, this torque wrench is a trusted choice for professionals worldwide.

Frequently Asked Questions (FAQ)
-
Q: How accurate is the torque wrench?
A: The wrench is factory calibrated to ±3% of indicated value from 20% to 100% of the torque range. A calibration certificate is included. If you require higher accuracy (e.g., ±2%), please inquire about our premium models. -
Q: How does the self-locking mechanism work?
A: After you set the desired torque value and tighten the locking collar, the mechanism prevents the setting from rotating accidentally. When tightening a fastener, an audible click and a slight release indicate the preset torque has been reached, and the handle will not continue to turn until you reduce force. -
Q: Is the calibration certificate from an accredited lab?
A: Our standard certificate is issued in-house with traceability to national standards. If you need an ISO/IEC 17025 accredited calibration certificate, please specify when ordering (additional fee applies). -
Q: What is covered under the 2-year warranty?
A: The warranty covers defects in materials and workmanship under normal use. It does not cover damage from misuse, unauthorized repair, or abuse. Please see full warranty terms on our website. -
Q: Can I use this wrench in both clockwise and counterclockwise directions?
A: Yes, the wrench operates in both directions. However, the self-locking feature is typically active only in the tightening direction (clockwise). For reverse (counterclockwise) use, the locking may need to be disengaged; please refer to the manual. -
Q: What is the recommended storage condition?
A: Store the wrench in the provided case at room temperature, away from moisture and extreme heat. It is recommended to set the torque to the lowest value before storage to relieve spring tension and prolong accuracy. -
Q: Do you offer customization like special markings or non-standard ranges?
A: Yes, we can customize the wrench with your logo, specific torque range (within our manufacturing capability), or a custom calibration certificate. Minimum order quantities may apply. Contact our sales team for details. -
Q: What markets do you serve?
A: We export to over 10 major markets including North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, East Asia, Western Europe, Central America, Northern and Southern Europe, South Asia, and domestic China. Our annual export value exceeds US$100 million.
