Hallowell Sr, presents a version of events  in which SPS developed a hex socket drive in-house, independently of Allen, circa By simply driving setscrews into selected holes, the hub mechanism conveniently operates to rigidly lock or definitely release from the shaft, without hammering or hub-pulling. It is much more difficult to turn a damaged rounded or otherwise internal fastener than an external one. Others[ edit ] A Scotch key or Dutch key features a circular keyway hole instead of rectangular , produced by drilling axially into the assembled hub and shaft, with a metal dowel pin serving as the key. SPS at the time was a prominent maker of shaft hangers and collars , the latter of which were set in place with set screws. In the absence of approval by the engineer for use of other hole types, standard holes shall be used in high strength bolted connections.

The synonym zeta key or wrench refers to the sixth letter of the Greek alphabet. The term hex-head is sometimes used to refer to this type of drive, but this use is not consistent with its more conventional use referring to external-wrenching hexagons.
Some features of hex keys are: The tool is simple, small and light The contact surfaces of the screw or bolt are protected from external damage There are six contact surfaces between bolt and driver The tool can be used with a headless screw The screw can be inserted into its hole using the key Torque is constrained by the length and thickness of the key Very small bolt heads can be accommodated The tool can be manufactured very cheaply, so one is often included with products requiring end-user assembly Either end of the tool can be used to take advantage of reach or torque The tool is L-shaped and was initially designed to be used with both sides The tool can be reconditioned using an electric grinder by removing the worn-out part, and then it works like new The hexagon is typically a smaller diameter than would be used with an external cap, and is more likely to round off its contact surfaces.
It is much more difficult to turn a damaged rounded or otherwise internal fastener than an external one. Extant records suggest without offering exhaustive documentation that the idea of a hex socket screw drive was probably conceived as early as the s to the s, but that such screws were probably not manufactured until around Rybczynski describes a flurry of patents for alternative drive types in the s to the s in the US,  which are confirmed to include internal-wrenching square and triangle types that is, square and triangular sockets U.
Patent , , but he explains that these were patented but not manufactured due to the difficulties and expense of doing so at the time. Robertson , of Milton , Ontario , Canada , first commercialized the square socket in , having perfected and patented a manufacturing method cold-forming, using the right material and the right die design. In —, William G. Allen patented a method of cold-forming screw heads around a hexagonal die U. Published advertisements for the "Allen safety set screw" by the Allen Manufacturing Company of Hartford, Connecticut, exist from Hallowell Sr, presents a version of events  in which SPS developed a hex socket drive in-house, independently of Allen, circa From this came the Unbrako line of products.
Drove it through the base of Jake's spine. As I fingered her, she wanked me off brutally, showing no mercy for this young and inexperienced penis. They walked together down it to it's end, both embraced, their tongues in each others mouth. they were porno's. He was covered from head to toe in blood and flesh.
Parallel keys[ edit ] Parallel keys are the most widely used. They have a square or rectangular cross-section. Square keys are used for smaller shafts and rectangular faced keys are used for shaft diameters over 6. Set screws often accompany parallel keys to lock the mating parts into place. The circular segment can be cut directly by plunge cutting with a circular Woodruff cutter without any reliefs.
The main advantage of the Woodruff key is the elimination of milling near shaft shoulders, where stress concentrations ,  and concentricity would be affected.
The more exact fit of the key and keyway also reduces play, and stress concentrations in, and improves the reliability of the key. An additional advantage is a stuck key can be removed from a shaft with a hammer blow, the circular profile will push the key out of the slot, as opposed to a standard key which will need to be pushed axially, or pulled out of its slot. Common applications include machine tools , automotive applications, snowblowers and marine propellers.
This type of key was developed by W. The keyway in the hub has a taper that matches that of the tapered key. Some taper keys have a gib, or tab, for easier removal during disassembly. The purpose of the taper is to secure the key itself, as well as, to firmly engage the shaft to the hub without the need for a set screw.
The problem with taper keys is that they can cause the center of the shaft rotation to be slightly off of the mating part.
First and second symbols different regardless of 3rd: No reward Any 2 matching with bell at the end: One to Three piles of Cash Two bells with any non-psycho mask at the end: One to Three piles of Cash 3 Bells: Three Piles of Cash 3 sevens: Character skin from a manufacturer e.
Any 2 matching with psycho mask at the end: White weapon 3 cherries: Or, rarely, purple weapon and sometimes the chance for character or vehicle skins. Purple weapon, or very rarely other colors including white.
The slot machine will drop a live grenade from the reward box, similar to the ones that Suicide Psychos use, and say "Boom time! This is a completely normal grenade and will damage any player character in the blast radius, not just the Vault Hunter who actually used the slot machine. The damage dealt by the grenade is scaled to the level of loot in the machine. Stack of 4 Eridium bars.
On rare occasions a jackpot will trigger that spews out around a dozen stacks of single eridium bars. Two stacks of 4 Eridium bars 8 total 3 triple Eridium bars: All non-pistol weapons from the side drawer. Live grenades and eleven of the twelve eridium bars from a triple eridium reward will drop to the floor. Probability of Winning With each slot pull, a value ranging from 0 to 32, - 1 is assigned. Assuming that this value is randomly assigned, probabilities of winning can be obtained, although some winnings are locked until a certain point in the story.
