## Description

FIRSTINFO H5178 Precision Certified Torque Limiting Screwdriver, 1/4 Inch Hex Quick Release Bit Holder, 0.1-1.2 Nm/1.33-10.18 In-lb with Double Scale - desertcart.com

Review: Just what I needed. - I needed a torque wrench for electrical work. This was easy to adjust, felt solid, and performed well. I easily tightened to 50 in-lb. I appreciate the calibration sheet. It increased my confidence that the unit is within spec. I would have liked a better case. What’s provided is fine to protect it and for occasional use. Also it’s compact. However, for regular use would be a little inconvenient.
Review: Excellent torque screwdriver for small applications - We got one of these at work for determining our needed torque on some semiconductor test sockets. This tool really rocks, and beats the pants off the digital "toy" torque screwdrivers. This tool will actually cam-over when you hit the target torque, so you cannot over-tighten. It is easily adjustable, although it can be a small pain to hold the gold adjustment ring while locking/unlocking the torque setting. It fits whatever 1/4" bit you have, so it doesn't really limit you. NOTE: For those who don't know, ALWAYS return a torque-device to its lowest setting when you are done. Don't leave it at a particular setting, or you risk the spring mechanism taking a "set."

## Features

- 【 Dual Scale / Calibration Certification Included 】 Torque ranges from 0.1 to 1.2 Nm (1.33 to 10.18 in. lbs.) with a dual scale, in 0.01 Nm increment, featuring aluminum scale and tube to reduce weight and enhance durability. ±6% accuracy, certified in accordance with ASME B107.300-2010 and ISO 6789.
- 【 Automatically Slip When Reaching the Desired Torque 】 The torque adjustment is intuitive and easy for setting. The torque limited feature causes the screwdriver to slip automatically once the selected torque is reached to avoid damage to the screw being driven.
- 【 Quick Release Design 】 Just press the ring knob for assistance when adjusting the torque; release the ring knob when reaching the setting torque value. Ergonomic shape with non-slip and comfortable features. Equipped with quick release bit holder for easily attaching and releasing the bit.
- 【Stronger and Durable Construction】 Made of premium aluminum alloy steel which can reach the exacting tolerance, also reducing weight and enhancing durability.
- 【 Taiwan Design & Manufacture 】 We provide you with quality tools with 12 months of after-sales warranty support. Help you to achieve a satisfactory shopping experience.

### ⭐⭐⭐⭐⭐ Well-thought out, but can't always loosen what it tightens.
*by M***D on July 3, 2025*

Fantastic! High quality. Very well thought out. Easy to adjust and lock in the torque setting. For better and worse, this screwdriver is bi-directionally torque-limiting. (good for left handed screws too) Some times, it can tighten a screw, but torque-limits when trying to remove the same screw. I would greatly appreciate a right handed version with higher torque for loosening right handed screws. (Maybe about 25%-50% extra torque)
