1,Description:

Hub nuts are special nuts used to fix the outer hubs of cars. Due to the uncertainty of automotive nuts, there is no national standard for automotive nuts. However, the general models are roughly the same as ordinary hexagonal nuts, and there are various models ranging from M12 to M42. Compared with ordinary hexagonal nuts, hub nuts are generally thicker than hexagonal national standard nuts of the same specification, and they are usually fine threads. The thread pitch is roughly 1.5 millimeters and 2.0 millimeters. The shape is the same as that of hexagonal nuts, which is an equal-sided hexagon. However, there is a taper at one end of the nut. Some of the conical ones have a step inside to place the nylon gasket for locking, while others have no step on the side! Some hub nuts have a flange at the conical part. Generally, only when there is a flange on the outside will there be a step inside to place the nylon washer. The common ones are roughly hexagonal nuts with a conical shape!

surface color category: according to different needs, the surface has plated white, army green, color yellow, corrosion resistant Dacromet.
flange type: according to the use of flange bolts in different positions, the size of the plate requirements are different

It needs to be combined with the nut to fasten the parts connecting two through holes, so the bolt connection is a detachable connection.

hexagonal head type: one is flat brain, the other is concave brain.

2,Applications:

Hub bolts are high-strength bolts that connect the wheels of a vehicle. The connection position is the hub unit bearing of the wheel! Generally, 10.9 grade is used for mini cars, while 12.9 grade is used for medium and large vehicles! The structure of hub bolts is generally composed of knurled spline gears and threaded gears! And a hat head!
Most T-shaped head wheel hub bolts are of grade 8.8 or above, and they are responsible for the large torque connection between the car wheel hub and the axle!
Most double-ended wheel hub bolts are of grade 4.8 or above, and they are responsible for the connection between the outer wheel hub housing and the tires of the vehicle with relatively light torque
