Lug nut

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.

Design

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.

Some designs (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 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. Honda uses a spherical rather than a tapered seat, but the nut performs the same function. 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.

Nut (fruit)

A nut is a fruit composed of a hard shell and a seed, which is generally edible. In a general context, however, a wide variety of dried seeds are called nuts, but in a botanical context, there is an additional requirement that the shell does not open to release the seed (indehiscent). The translation of "nut" in certain languages frequently requires paraphrases, as the word is ambiguous.

Most seeds come from fruits that naturally free themselves from the shell, unlike nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. The general and original usage of the term is less restrictive, and many nuts, such as almonds, pecans, pistachios, walnuts, and Brazil nuts, are not nuts in a botanical sense. Common usage of the term often refers to any hard-walled, edible kernel as a nut.

Botanical definition

A nut in botany is a simple dry fruit with one seed (rarely two) in which the ovary wall becomes very hard (stony or woody) at maturity, and where the seed remains unattached or free within the ovary wall. Most nuts come from the pistils with inferior ovaries (see flower) and all are indehiscent (not opening at maturity). True nuts are produced, for example, by some plant families of the order Fagales.

Nameless One

The Nameless One is a two-headed demon. The Nameless One first appeared in Sub-Mariner #22 (February 1970), and was created by Roy Thomas and Marie Severin. He was the leader of the Undying Ones, and led them to conquer the Earth millennia ago. The Undying Ones ruled the Earth for ages, though eventually their powers waned and were forced to return to their own realm. The Nameless One continued to rule them when they were exiled from Earth, and during several attempts to conquer it again in modern times. Later, another demon became a successor to the previous, two-headed Nameless One as leader of the Undying Ones. This demon tried to use Wolverine to kill Doctor Strange. Wolverine, enhanced by demonic magic, slew this Nameless One and many of the Undying Ones.

Lug (knob)

A Lug (knob) is a typically flattened protuberance, a knob, or extrusion on the side of a vessel: pottery, jug, glass, vase, etc. They are sometimes found on prehistoric ceramics/stone-vessels such as pots from Ancient Egypt, Hembury ware, claw beakers, and boar spears.

A lug may also only be shaped as a lip for suspension–(no hole). In Ancient Egypt, lugs contained a hole for suspension, with 2– or 3–lugged vessels most common.

In Roman times, lugs were on some types of column-sections to aid in construction. After slung by rope into position with a crane, the lugs were then masoned off.
