Muzzle devices with a timed alignment requirement, such as brakes and flash hiders with directional ports, need to end up clocked correctly when torqued. This Gemtech shim set for 7.62mm threads in 5/8x24 gives you a range of thicknesses so you can dial the final position exactly without over- or under-torquing the device.

Stacking shims is the standard, gunsmith-approved method for timing a muzzle device on a shouldered barrel, and having a full set on hand saves a trip when a device lands a few degrees off.
