Tool
For ¼-inch bolts. Some nuts and bolts require a second wrench
to prevent turning.
For 5/16-inch bolts. Two of the canister nuts are not accessible
with a socket wrench. Some nuts and bolts require a second
wrench to prevent turning.
With ½-inch and 7/16-inch sockets capable of torquing to 15 ft-lb.
For J-type radio.
For cradle-type radio. The 7/64-inch hex key is included in the
antenna kit.
For socket-head cap screws (Allen screws) with a 3-mm
