It depends on the muzzle brake. Some brakes require a tool for installation, while others do not. Consult your brake manufacturer to be sure.
If a tool is required, it will most likely be a wrench or a tap and die set. Be sure to have the proper tools before attempting to install your brake, as improper installation can result in damage to both the brake and the barrel of your firearm.
