A hollow, tapered shaft centers the wheel on the hub. Torque is transmitted by pins and matching holes at the hub-wheel interface. The retaining nut requires a large amount of torque to secure, therefore a long-handled torque wrench or a powerful impact wrench (also called a "wheel gun") is used to
A distorted thread locknut, [1] is a type of locknut that uses a deformed section of thread to keep the nut from loosening due to vibrations, or rotation of the clamped item. There are four types: elliptical offset nuts, centerlock nuts, toplock nuts and partially depitched (Philidas) nuts.

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.
Rarely, and more often with large trucks and lorries, insufficient force can lead to the nuts coming undone while in use. Because of this, it is best to use a torque wrench or similar tool to finally tighten the wheel lug nuts to the proper torque specification as soon as possible after using a lug wrench to affix a wheel.
Bullseye shooting is a category of shooting sport disciplines where the objective is to score points with carefully placed precision fire by hitting a target as close to its center as possible. The name refers to the target center's nickname, the " bull's eye ".
NRA Precision Pistol, formerly known as NRA Conventional Pistol, [1] is a national bullseye shooting discipline organized in the United States by the National Rifle Association of America. Emphasis is on accuracy and precision, and participants shoot handguns at paper targets at fixed distances and time limits.
With lug bolts, on the other hand, the whole hub usually has to be replaced in case of stripped threads in the hub. One motivation for using lug bolts instead of wheel studs and nuts the number of parts that needs to be attached to the wheel hub. Wheel studs and lug nuts consist of two parts, while the lug bolt is a single part.
For shooting sport, accuracy is the gun's ability to hit exactly what the shooter is aiming at, and precision is the ability to hit the same place over and over again in a repeatable fashion. Both are the goals of accurizing, [ 2 ] which generally concentrates on four different areas:
