Safety Wire
A safety wire or locking-wire is a type of positive locking device that prevents fasteners from falling out due to vibration and other forces. The presence of safety wiring may also serve to indicate that the fasteners have been properly tightened. Safety wire is available in a variety of American wire gauge, gauges and materials, depending on the application. In aircraft and racing applications, stainless steel wire is used, such as in diameter. Typically, the wire is threaded through a hole drilled into a fastener or part, then twisted and anchored to a second fastener or part, then twisted again. Application Principle There are a few techniques for different applications. The word ''safetying'' is universally used in the aircraft industry. Briefly, safetying is defined as: "Securing by various means any nut, bolt, turnbuckle etc., on the aircraft so that vibration will not cause it to loosen during operation." These practices are not a means of obtaining or maintaining t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Wiring - Jaguar Rear Subframe
Safety is the state of being protected from harm or other danger. Safety can also refer to risk management, the control of recognized hazards in order to achieve an acceptable level of risk. Meanings The word 'safety' entered the English language in the 14th century. It is derived from Latin , meaning uninjured, in good health, safe. There are two slightly different meanings of "safety". For example, "home safety" may indicate a building's ability to protect against external harm events (such as weather, home invasion, etc.), or may indicate that its internal installations (such as Home appliance, appliances, stairs, etc.) are safe (not dangerous or harmful) for its inhabitants. Discussions of safety often include mention of related terms. Security is such a term. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence.

Cotter (pin)
A cotter is a pin or wedge with a flat bearing surface passing through a hole to fix parts tightly together. In British usage cotter pin has the same meaning,. but in the U.S. it means a split pin. Typical applications are in fixing a crank to its crankshaft, as in a bicycle, and a piston rod to a crosshead, as in a steam engine. The angle of the wedge determines the position of the parts being held; therefore, on a bicycle, the pedal arms will only be at 180 degrees to each other if the angle of the cotter pin's wedge is the same on both pins. Popular usage Formerly, it was common to mount bicycle A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered transport, human-powered or motorized bicycle, motor-assisted, bicycle pedal, pedal-driven, single-track vehicle, with two bicycle wheel, wheels attached to a ... cranks using a cotter, although now a more easily maintained arrangement is typically used, such as a square tapered or splined inte ...

Castellated Nut
A castellated nut, sometimes referred to as a castle nut, is a nut with slots or notches cut into one end. The name comes from the nut's resemblance to the crenellated parapet of a medieval castle. Castellated nuts are sometimes incorrectly referred to as castigated nuts. While castellated nuts are often referred to as slotted nuts, from a technical perspective, slotted nuts differ slightly from castellated nuts. Castellated nuts are formed with a round section at the top where the slots are located. Slotted nuts do not have this rounded modification. The flat sides of slotted nuts extend fully from the top to the bottom of the nut. Both castellated and slotted nuts are designed to use a pin (usually a split pin) that fits through the slots and through a hole in the screw to which the nut is attached. This pin prevents the nut from turning and loosening. Compared with slotted nuts, castellated nuts allow the cotter pin to be confined closer to the margins of the nut itsel ...

Thread-locking Fluid
Thread-locking fluid or threadlocker is a single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion. Most thread-locking formulas are methacrylate-based and rely on the electrochemical activity of a metal substrate to cause polymerization of the fluid. Thread-locking fluid is thixotropic, which allows it to flow well over time, yet still resist shocks and vibrations. It can be permanent or removable; in the latter case, it may be removable merely by force or may also require heating, for example. Typically, brands are color-coded to indicate strength and whether they can be removed easily or require heat for removal. History Thread-locking fluid was developed by American professor Vernon K. Krieble in 1953. His company, American Sealants, founded the Loctite brand. An early version of the compound was patented in 1960. Properties Typically, thread-locking fluids are methacrylate-based, and cur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jam Nut
A jam nut is a low profile type of nut, typically half as tall as a standard nut. It is commonly used as a type of locknut, where it is "jammed" up against a standard nut to lock the two in place. It is also used in situations where a standard nut would not fit. The term "jam nut" can also refer to any nut that is used in the same function (even a standard nut used for the jamming purpose). Jam nuts, other types of locknuts, lock washers, and thread-locking fluid are ways to prevent vibration from loosening a bolted joint. Use of two nuts to prevent self-loosening In normal use, a nut-and-bolt joint holds together because the bolt is under a constant tensile stress called the ''preload''. The preload pulls the nut threads against the bolt threads, and the nut face against the bearing surface, with a constant force, so that the nut cannot rotate without overcoming the friction between these surfaces. If the joint is subjected to vibration, however, the preload increases and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locknut
A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut,. stiff nut or elastic stop nut, is a Nut (hardware), nut that resists loosening under vibrations and torque. Prevailing torque nuts have some portion of the nut that deforms elastic deformation, elastically to provide a locking action. Free-spinning locknuts exist which carry the advantage of not requiring extra torque until seated. Types There are various kinds of specialised lock nuts, including: * Castellated nut * Distorted thread locknut **Centerlock nut **Elliptical offset locknut **Toplock nut **Philidas nut * Interfering thread nut **Tapered thread nut * Jam nut * Jet nut (K-nut). * Keps nut (K-nut or washer nut) with a free-spinning washer. In the locknut form, this is a star-type lock washer. * Plate nut * Polymer insert nut (Nyloc nut) * Security locknut All steel reusable nut for high vibration and harsh environments. * Serrated face nut * Serrated flange nut * Speed nut ...

Lock Washer
A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration ( rubber washer). Washers are usually metal or plastic. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to brinelling after the torque is applied. Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces. They may also be used in rotating applications, as a bearing. A ''thrust washer'' is used when a rolling element bearing is not needed either from a cost-performance perspective or due to space restraints. Coatings can be used to reduce wear and friction, either by hardening the surface or by providing a solid lubricant (i.e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drill Bit
A drill bit is a cutting tool used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the ''shank'' in the chuck. Drills come in standardized drill bit sizes. A comprehensive drill bit and tap size chart lists metric and imperial sized drills alongside the required screw tap sizes. There are also certain specialized drill bits that can create holes with a non-circular cross-section. Characteristics Drill geometry has several characteristics: * The spiral (or rate of twist) in the drill bit controls the rate of chip removal. A fast spiral (high twist rate or "compact flute") drill bit is used in high feed rate applications under low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drill Press
A drill press is a Drill, drilling machine suitable for quick and easy drilling of straight holes, Countersink, countersinking or Counterbore, counterboring that are perpendicular to both directions of a table surface. In comparison, it is more difficult and less repeatable to drill perpendicularly with a hand-held drill. Two common variants are the benchtop drill press for mounting to a workbench and the larger floor-standing drill press for mounting to the floor, and they should preferable be securely mounted to prevent them from tipping over. A special variant is the magnetic drilling machine, which is a mobile drilling machine intended to be magnetically clamped during use, and is used to some extent for field repairs and production in industry. Drill presses can be divided into two main types depending on their construction: * Column drill press is a common type characterized by the fact that the drill spindle can be moved up and down Axis of rotation, axially ("along a colu ...

Drill Jig
A drill is a tool used for making round holes or driving fasteners. It is fitted with a drill bit for making holes, or a screwdriver bit for securing fasteners. Historically, they were powered by hand, and later mains power, but cordless battery-powered drills are proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, and utility projects. Specially designed versions are made for surgery, dentistry, miniatures, and other applications. History Around 35,000 BC, ''Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The earli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
