Locking lug nuts are a great way to prevent expensive wheels and rims from being stolen. What's not so great is not being able to find the special key needed to remove them when it's time to change brake pads or rotate the tires. With the Steelman Pro 16-Piece Locking Lug Master Key Set on hand, you can get the job done quickly and easily. This set was designed explicitly for the purpose of easily removing locking lug nuts on aftermarket wheels and includes lug keys for a wide variety of security lug styles currently on the market. Each key is made from heat-treated chrome vanadium steel with a corrosion-resistant black oxide finish for a lifetime of reliable use. The double hex-head design allows the keys to be used with both 13/16 and 7/8-inch lug and combination wrenches. Thin socket walls and an extra-long design helps to keep wrenches away from the wheel during use to prevent nicks and scratches. This set includes Spline Style Keys: 5-spline 5/8-inch, 6-spline 41/64 and 45/64-inch, 7-spline 5/8, 11/16, and 3/4-inch, and 12-spline 11/16 and 13/16-inch, Hex Keys: 9/16-inch, 12mm, 12mm fluted, and 15mm, and Star Keys: 8-point 7/16 and 5/8-inch, 9-point 1/2-inch, and 10-point 1/2-inch. For easy storage, the keys come with a handy blow-molded plastic case with an application guide included on the inner lid.
