Torx
Torx (pronounced ) is a trademark for a type of screw drive characterized by a 6-point star-shaped pattern, developed in 1967, Bernard F. Reiland, "Coupling arrangement and tools for same", filed 1967-03-21 by Camcar Textron. A popular generic name for the drive is ''star'', as in star screwdriver or star bits. The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal. This is sometimes abbreviated in databases and catalogs as 6lobe (starting with the numeral ''6'', not the capital letter ''G''). Torx Plus, Torx Paralobe and Torx ttap are improved head profiles. Torx screws are commonly found on automobiles, motorcycles, bicycle brake systems ( disc brakes), hard disk drives, computer systems and consumer electronics. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available. However, as torx drivers became mor ...

Slot Head
At a minimum, a screw drive is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. Some of the less-common drives are classified as being "tamper-resistant". Most heads come in a range of sizes, typically distinguished by a number, such as "Phillips #00". Overview Slotted drives Slot Slot screw drives have a single horizontal indentation (the ''slot'') in the fastener head and is driven by a "common blade" or flat-bladed screwdriver. This form was the first type of screw drive to be developed, and, for centuries, it was the simplest and cheapest to make because it can just be sawed or filed. Blunt or damaged tools can easily be re-ground as required in any workshop. It is unique because the slot head is straightforward to manufacture, and because it can be driven by a simple handtool. The ''slotted screw'' is commonly found in existing p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentalobe
The pentalobe security screw (Apple nomenclature), or pentalobe screw drive, is a five-pointed tamper-resistant system used by, but not limited to, Apple in their products. Pentalobe screws were adopted by Apple starting in 2009, when they were first implemented in the 15-inch MacBook Pro. They have since been used on other MacBook Pro, MacBook Air and iPhone models. Apple attracted criticism upon the introduction of the pentalobe screw; it was seen by some as an attempt to lock individuals out of their devices. In response, inexpensive pentalobe screwdrivers, manufactured by third parties, have become relatively easy to obtain. Pentalobe screw sizes include TS1 (0.8 mm, used on every iPhone starting with the iPhone 4s), TS4 (1.2 mm, used on the MacBook Air and the MacBook Pro with Retina display), and TS5 (1.5 mm, used on the 2009 MacBook Pro battery). The TS designation is ambiguous as it is also used for the Torq-set screw drive. Usage iPod Various models o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screwdriver
A screwdriver is a tool, manual or powered, used for turning screws. Description A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. This form of the screwdriver has been replaced in many workplaces and homes with a more modern and versatile tool, a power drill, as they are quicker, easier, and can also drill holes. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional "grip". Handles are typically wood, metal, or plastic and usually hexagonal, square, or oval in cross-section to improve grip and prevent the tool from rolling when set down. Some manual screwdrivers have interchangeable tips that fit into a socket on the end of the shaft and are held in mechanically or magnetically. These often have a hollow handle that ...

Tamper Resistance
Tamperproofing is a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system. Since any device or system can be foiled by a person with sufficient knowledge, equipment, and time, the term "tamperproof" is a misnomer unless some limitations on the tampering party's resources is explicit or assumed. Tamper resistance is resistance to intentional malfunction or sabotage by either the normal users of a product, package, or system or others with physical access to it. Tamper resistance ranges from simple features like screws with special drives and tamper-evident seals to more complex devices that render themselves inoperable or encrypt all data transmissions between individual chips, use of materials needing special tools and knowledge. Tamper-resistant devices or features are common on packages to deter package or product tampering or enable its detection. Anti-tamper devices have one or more components: tamper resistance, ...

Cam Out
Cam out (also cam-out or camming out) is a process by which a screwdriver slips out of the head of a screw being driven once the torque required to turn the screw exceeds a certain amount. Repeatedly camming out damages the screw, and possibly also the screwdriver, and should normally be avoided. Phillips screwdriver The Phillips screwdriver design has a tendency to cam out during operation due to angled contact surfaces, which create an axial force pushing the driver out of the recess as torque is applied. Despite popular belief, there is no clear evidence that this was a deliberate design feature. When the original patent application was filed in 1933, the inventors described the key objectives as providing a screw head recess that (a) may be produced by a simple punching operation and which (b) is adapted for firm engagement with a driving tool with "no tendency of the driver to cam out". Nevertheless, the tendency of the Phillips screw to easily cam out was found to be an adv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screw Head - Torx Paralobe
A screw is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to the head. The most common uses of screws are to hold objects together and there are many forms for a variety of materials. Screws might be inserted into holes in assembled parts or a screw may form its own thread. The difference between a screw and a bolt is that the latter is designed to be tightened or released by torquing a nut. The screw head on one end has a slot or other feature that commonly requires a tool to transfer the twisting force. Common tools for driving screws include screwdrivers, wrenches, coins and hex keys. The head is usually larger than the body, which provides a ''bearing surface'' and keeps the screw from being driven deeper than its length; an exception being the ''set screw'' (aka grub screw). The cylindrical portion of the screw from the underside of the head to the tip is called the ''shank''; it may be fully or partially ...

Bicycle Brake Systems
A bicycle brake reduces the speed of a bicycle or prevents the wheels from moving. The two main types are: #Rim brakes, rim brakes and #Disc brakes, disc brakes. Drum brakes are less common on bicycles. Most bicycle brake systems consist of three main components: a mechanism for the rider to apply the brakes, such as #Brake levers, brake levers or Bicycle pedal, pedals; a mechanism for transmitting that signal, such as Bowden cables, hydraulic hoses, #Rod-actuated brakes, rods, or the bicycle chain; and the brake mechanism itself, a #Rim brakes, caliper or #Drum brakes, drum, to press two or more surfaces together in order to convert, via friction, kinetic energy of the bike and rider into thermal energy to be Dissipation, dissipated. History Karl Drais included a pivoting brake shoe that could be pressed against the rear iron tyre of his 1817 . This was continued on the earliest bicycles with pedals, such as the Boneshaker (bicycle)#Boneshaker, boneshaker, which were fitted with ...
