Sizes of wheel nuts of Chevrolet Blazer

home ⇒ equipment ⇒ wheel fastener ⇒ chevrolet

For the Blazer model, the wheel is attached to the hub using wheel nuts. The number of fasteners depends on the Blazer year of manufacture and is presented in the table below.

Total dimensions of fasteners:

Number of fasteners: from 5 to 6;
Fastener size: from 1/2in20UTF to M14x1.5;
Diameter of the mounting holes (PCD): from 120.65 to 139.7;
Disc offset (ET): from 70.10 to 78.30.

Important: the above data are limits for all vehicle modifications, specific figures depend on the year of manufacture.

Rules for selecting wheel fasteners:

Different wheel fasteners are often used for cast and stamped disks - this applies to the length of the bolts, since the thickness of different types of disks can vary significantly.

When selecting any fasteners, special attention should be paid to the thread pitch. This parameter is always indicated after the “x” in the marking.

Most of the wheel fasteners have metric threads with fine pitch (М12х1.25/М12х1.5/М14х1.25/М14х1.5), which must correspond to the threads of thread studs or threaded holes in the wheel hub.

Important: the marking of fastener bolt M12x1.5 is deciphered as follows: thread with a nominal diameter of 12 (mm), thread pitch 1.5 (mm).
