Your Complete Guide

【Two Ways to Use】 The adjustable torque wrench can measure a 14mm x 18mm open end and comes with a 38mm spanner head and a 1/2" 72-tooth ratchet head. Choose the method that best fits your needs.

【Interchangeable Heads】 This unique design allows you to easily switch between different heads, including ratchet, spanner, and torx. Diversify your uses and save time by not needing to carry multiple tools.

【High Accuracy】 Our 1/2 inch drive torque wrench offers ±3% precise accuracy in both clockwise and counterclockwise directions. With dual scales of 10-170 Ft-Lb/13.6-230.5 Nm, it meets all your needs. The scales are clear and durable, not easy to wear.

【Easy to Feel the Click】 Pull down the lock knob and hold it until the torque setting is completed. When you reach the preset torque value, you will hear a ‘click’ from the wrench. This helps you know when to stop applying force without over-tightening.

【Wide Application】 The HVAC torque wrench is perfect for tightening and loosening nuts and bolts in tight spaces. It’s a versatile tool for professionals working on motorcycles, cars, refrigeration systems, HVAC, mini-split air conditioners, and industrial repairs. For changing the ratchet and jaw heads, use a 4mm flat head hex wrench.
