The sleeve is a cylindrical tool used to disassemble nuts or bolts, and its inner surface has a hexagonal cross-section. The specifications of the sleeve are divided into English system and metric system. The sleeves of the inch specifications are incremented by 1:16 inches and 1:32 inches; the sleeves of the metric specifications are incremented by 1 cm. For car owners, a sleeve is needed when disassembling tires or spark plugs.

When using a sleeve, you must not choose a sleeve that fits the nut or bolt completely. If you use a sleeve larger than the nut or bolt, the sleeve will easily round the nut or bolt head during rotation. . When disassembling relatively tight wheel bolts, if a suitable extension rod is put on the sleeve handle, the rotating torque can be increased and the wheel bolts are easier to loosen. It is important to note that if you use the sleeve handle extension rod when tightening the wheel bolts, remember not to use too much force to prevent the rotation torque from exceeding the bearing range of the nut or bolt, otherwise the nut or bolt will be easily damaged.
