A sleeve is a cylindrical tool used for disassembling and installing nuts or bolts, with a hexagonal cross-section on its inner surface.

A sleeve is a cylindrical tool used for disassembling and installing nuts or bolts, with a hexagonal cross-section on its inner surface. Sleeve specifications are divided into two types: imperial and metric. The British socket specifications increase by 1/16 inch and 1/32 inch; The metric sleeve specifications increase by 1 millimeter. For car owners, a socket is required when dismantling tires or spark plugs.

When using a sleeve, be sure to choose a sleeve that matches the nut or bolt perfectly. If an oversized sleeve is used, it is easy for the sleeve to wear the head of the nut or bolt during rotation. When disassembling tighter wheel bolts, a suitable extension rod can be fitted onto the socket handle to increase the rotational torque, making it easier to loosen the bolts. It should be noted that when tightening the wheel bolts, use a socket handle extension rod and do not apply excessive force to prevent the rotational torque from exceeding the bearing range of the nut or bolt, which may cause damage to the nut or bolt.
