## Description

FIRSTINFO 3.4:1 Compact Torque Multiplier Wrench 600 Nm (443 ft-lbs) | 1/2" Drive Male to Female Adapter, Labor Saving Tool for Lug Nut, Easy Tire Change, F3220DD - desertcart.com

Review: Adapter - Very useful torque adapter
Review: Excellent for the price - Important first note, I only used this to torque a nut to 500 ft/lbs so I didn't push it to its claimed limit. This worked perfectly for me and was incredibly less expensive than a torque wrench with the same capability would have been. The multiplier has a range of accuracy of something like 4% which has to be figured along with the accuracy of the torque wrench you're using as well. This could result in a relatively large variance in actual torque applied but that's the payoff for saving a couple hundred dollars (minimum) on a higher capacity torque wrench.

Very useful torque adapter

### ⭐⭐⭐⭐⭐ Excellent for the price

Important first note, I only used this to torque a nut to 500 ft/lbs so I didn't push it to its claimed limit.

### ⭐⭐⭐⭐⭐ Super torque in a little package
*by S***R on January 22, 2021*

I bought this to remedy having using a super long cheater pipe's on socket wrenches to get extra torque for breaking loose or tightening big nuts/bolts over 300 ft/lbs. I fabricated a handle extension from steel tubing to use it for that application. Caution in drilling the handle as it is hardened steel. I put three stainless bolts thru and attached a 40+inch handle. This works similar to the much more expensive Torque multiplication wrenches costing $300.00 bucks and beyond. I can still use it as normal to break loose tire lug nuts since the handle is mounted on the outside of the arm, just reverse insert the multiplier thru the wrench opening (*its backwards displayed in my picture if you were loosening lug nuts on Tire). Price and quality are good Satisfied customer
