A hairpin clip, also known as a retaining pin, [1] is a type of formed wire used on a grooved shaft. It is designed to be easily installed and uninstalled, and is reusable. They are commonly made from 1050 carbon steel and 300 series stainless steel. [2]
A hairpin or hair pin is a long device used to hold a person's hair in place. It may be used simply to secure long hair out of the way for convenience or as part of an elaborate hairstyle or coiffure. The earliest evidence for dressing the hair may be seen in carved "venus figurines" such as the Venus of Brassempouy and the Venus of Willendorf. The creation of different hairstyles, especially among women, seems to be common to all cultures and all periods and many past, and current, societies use hairpins.
A paper clip is a device used to hold sheets of paper together, usually made of steel wire bent to a looped shape. Most paper clips are variations of the Gem type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire. Common to paper clips proper is their utilization of torsion and elasticity in the wire, and friction between wire and paper. When a moderate number of sheets are inserted between the two "tongues" of the clip, the tongues will be forced apart and cause torsion in the bend of the wire to grip the sheets together.
A hairpin turn, named for its resemblance to a hairpin/bobby pin, is a bend in a road with a very acute inner angle, making it necessary for an oncoming vehicle to turn about 180° to continue on the road. Such turns in ramps and trails may be called switchbacks in American English, by analogy with switchback railways. In British English "switchback" is more likely to refer to a heavily undulating road—a use extended from the rollercoaster and the other type of switchback railway.
A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Welding is an example of creating permanent joints. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel.
A linchpin, also spelled linch pin, lynchpin, or lynch pin, is a fastener used to prevent a wheel or other part from sliding off the axle upon which it is riding. The word is first attested in the late 14th century and derives from Middle English elements meaning "axletree pin".
A pin is a device used for fastening objects or material together, and can have three sorts of body: a shaft of a rigid inflexible material meant to be inserted in a slot, groove, or hole ; a shaft connected to a head and ending in a sharp tip meant to pierce one or more pieces of soft materials like cloth or paper ; a single strip of a rigid but flexible material whose length has been folded into parallel prongs in such fashion that the middle length of each curves towards the other so that, when anything is inserted between them, they act as a clamp, or two strips of a rigid material bound together by a spring at one end so that, when the spring held open, one can insert some material between the prongs at the other end that, the spring allowed to close, then clamp the inserted material. According to their function, pins can be made of metals, wood, or plastic.
A split pin, also known in the United States as a cotter pin or cotter key, is a metal fastener with two tines that are bent during installation, similar to a staple or rivet. Typically made of thick wire with a half-circular cross section, split pins come in multiple sizes and types.
A bobby pin is a type of hairpin, usually of metal or plastic, used in coiffure to hold hair in place. It is a small double-pronged hair pin or clip that slides into hair with the prongs open and then the flexible prongs close over the hair to hold it in place. They are typically plain and unobtrusively colored, but some are elaborately decorated or jeweled. Bobby pins became popular in the 1920s to hold the new bobbed hairstyles.
The M67 grenade is a fragmentation hand grenade used by the United States military. The M67 is a further development of the M33 grenade, itself a replacement for the M26-series grenades used during the Korean and Vietnam Wars, and the older Mk 2 "pineapple" grenade used since World War I.
A barrette, also known as a hair clip, hair pin or clasp, is a clasp for holding hair in place. They are often made from metal or plastic and sometimes feature decorative fabric. In one type of barrette, a clasp is used to secure the barrette in place; the clasp opens when the two metal pieces at either side are pressed together.
A circlip, also known as a C-clip, Seeger ring, snap ring or Jesus clip, is a type of fastener or retaining ring consisting of a semi-flexible metal ring with open ends which can be snapped into place, into a machined groove on a dowel pin or other part to permit rotation but to prevent lateral movement. There are two basic types: internal and external, referring to whether they are fitted into a bore or over a shaft. Circlips are often used to secure pinned connections.

A circle cotter, also known as a cotter ring or split ring, is a formed wire fastener that is shaped like a circle, hence the name. The open end of the wire is in the middle of the cotter so when it is installed the inner tab is first installed in the hole. Because of this feature it is often used in applications where a sharp edge cannot be tolerated, such as fabric applications.
