The M7 NC-4255QH air impact wrench is very popular with anyone who does automotive repair. With its high torque ratings, this pneumatic wrench is great for tightening and loosening bolts, lug nuts, and stubborn fasteners. Users find its rubber handle comfortable to hold while working.

This M7 air tool features the manufacturer’s patented EZ Grease anvil. This is a hole in the tip of the anvil mechanism where you inject the M7 grease. This coats the rotating parts. Simply insert the syringe of M7 EZ Grease into the hole then depress the container’s plunger. The grease will travel down the drive and coat the anvil of this air impact wrench. This helps you save time and improves the torque and overall lifespan of your M7 NC-4255QH.
