Hairich Torque Wrench Set 1/4-3/8-1/2 in Drive — Click, Dual Range, 72-Tooth

Overview

Introducing the Hairich Torque Wrench Set, a versatile trio designed for precise fastening across common drive sizes. The set covers 1/4, 3/8, and 1/2 inch drives with distinct ranges: 20-240 in-lb (2.3-27.1 Nm) for small fasteners, 10-45 ft-lb (61 Nm) for mid-size tasks, and 10-170 ft-lb (13.6-230.5 Nm) for larger assemblies. Dual-range scales read in both ft-lb and Nm, and the system is pre-calibrated to ±3% for reliable consistency in real-world use.

The build blends durability with comfort. The main body uses chrome vanadium steel alloy for lasting strength, while the head features a ratchet mechanism with a reversing option to speed up work. The square knurled handle is crafted from an aluminum titanium alloy, delivering an ergonomic, confident grip for extended sessions.

How it helps you work

Setting torque is straightforward: pull down the locking knob, rotate to the desired value, then release to lock. The locking mechanism snaps back, securing the preset torque and reducing guesswork.

Feedback is clear: when the preset torque is reached, you’ll feel a light vibration and hear a decisive click, signaling completion without over-tightening. The head’s reversible design lets you switch direction on the fly, boosting efficiency in tight spaces.
