To Learn About Wheel Nuts History

Time: 2018-07-30

Nowadays,the cars are every where.Car has became daily transport.We all know the cars have wheels to drive,to make them move.The wheels must use wheel nuts or bolts to tighten wheels.Today,i just find some interesting things to share with your guys.Yes,it's the nuts history.
A lug nut or wheel nut is a fastener, specifically a nut, used to secure a wheel on a vehicle. Typically, lug nuts are found on automobiles, trucks (lorries), and other large vehicles using rubber tires.
A lug nut is a nut with one rounded or conical (tapered) end, used on steel and most aluminum wheels. A set of lug nuts are typically used to secure a wheel to threaded wheel studs and thereby to a vehicle's axles.Wheel bolt and washer, for alloy wheel,Spherical and conical wheel bolt.

Some designs (Audi, BMW, Mercedes-Benz, Saab, Volkswagen) use lug bolts instead of nuts, which screw into a tapped (threaded) hole in the wheel's hub or drum brake or disc. This configuration is commonly known as a bolted joint.
The conical lug's taper is normally 60 degrees (although 45 is common for wheels designed for racing applications), and is designed to center the wheel accurately on the axle, and to reduce the tendency for the nut to loosen, due to fretting induced precession, as the car is driven. One popular alternative to the conical lug seating design is the spherical, or ball seat. Automotive manufactures as Audi, BMW and Honda use this design rather than a tapered seat, but the nut performs the same function.[dubious – discuss][citation needed] Older style (non-ferrous) alloy wheels have a 1/2 to 1 inch cylindrical shank slipping into the wheel to center it and a washer that applies pressure to clamp the wheel to the axle.

Wheel lug nuts may have different shapes. Aftermarket alloy and forged rims often require specific lug nuts to match their mounting holes, so it is often required to get a new set of lug nuts when the rims are changed.

There are 4 common lug nut types:
1.cone seat
bulge cone seat
under hub cap
spline drive
That's what i am saying today,i'll see you next time.
