The DTI Washer, also known as Squirter Washers, allows the steel fabricator and erector to absolutely identify a structural bolt that is giving the proper compression to the connection. This helps to ensure that each bolt is being used at its maximum capacity which increases its longevity.
Bolts that have been identified as being in proper tension will stretch when under load. This is because they are still attached to their parent material and can't lengthen themselves. If the bolt appears to be getting shorter when it's being used, this means that it is not being used at its maximum capacity and should be replaced.
Tensioning devices were first introduced by De Troyer in 1872. Since then, many different types of tensioners have been developed by other manufacturers. The most popular type today is the double-acting hydraulic unitary tensioner used by Ford, GM, Chrysler, and VW. These units include a spring loaded plunger that goes into the hole of the bolt head when activated by a hydraulic system. This pushes the head of the bolt outward which allows it to be stretched by theDTI Washer.
Bolts that aren't in proper tension may appear to be tight or loose based on how much movement you see when shaking a vehicle frame.
Washers are used in bolting to strengthen the joint and prevent bolt fatigue caused by uneven loads. Washers also help distribute stress over a larger surface area, which increases the bolt's resistance to failure.
Washers come in two types: internal and external. Internal washers fit inside the threads of the bolts or screws. External washers have holes that match the size of the bolts or screws they're being used with. They can be flat or round. When selecting washers, keep in mind that the stronger the bolt, the thicker its washer should be. Thinner washers will not provide as much reinforcement as heavier ones.
External washers are useful for preventing your bolt from coming out of the hole it's installed in. If you need more support than a washer provides, use an anchor lock washer or a cotter pin.
Internal washers can be used in place of spacers when building forms of scaffolding. This saves time since you don't need to measure and cut each spacer individually. However, internal washers do not offer the same strength as spacers made out of steel or plastic, so they should not be used as the only form of reinforcement.
Most washers' principal function is to uniformly disperse the load of the threaded fastener with which they are used. Threaded fasteners provide strain on the material into which they are inserted. Washers lessen the danger of such damage by spreading the fastener's load equally throughout the material's surface. Although washers are available in a wide variety of shapes and sizes, they all perform this function.
The most common reason for applying a washer to a screw is so that it will not be necessary to remove the head while installing the screw. This is particularly important when you are using small screws into wood or plastic parts where their removal might be difficult or impossible. Even if you can still turn the screw after it has been installed, its removal would be easier if it did not have a head stuck on it.
Another reason people apply washers to screws is so that the heads will not show when the screw is used as part of a larger piece of work. For example, if you were making a bulletin board and decided to use a screw to attach the corner pieces together, without a washer the person installing the screw would never know if it was really tight enough against the wood or not. If it was too loose, the bulletin board would fall over; if it was too tight, the person would have to take it off and try again.
Yet another reason people apply washers to screws is because they want the head of the screw to show.
Metal washers are thin, disk-shaped plates with a hole that are used to distribute the load of a screw, nut, or other threaded fastener. They can be made for a range of industrial functions and product requirements. Metal washers come in different sizes, shapes, materials (including stainless steel), and tolerances. Washers are used to reduce the amount of material needed to produce a given load capacity. This is important because less material means less weight and volume for shipping purposes.
Washers also help to even out the pressure on parts of a screw head or bolt so they don't deform under stress. For example, if a screw has a flat head, it will only apply pressure on one side of the washer, leaving the opposite side free to move which could lead to scuffing or galling of the surface it contacts.
Thin metal washers are usually called washers but sometimes called spacers. Standard metal washers are not very thin—usually about 0.010" (0.25mm) or more—but they do get smaller as you go up in size. Spacer washers are thicker, with some coming in at 0.015" (0.38mm) or more.
The term washer is generally used for thin, circular objects while spacer is used for thicker, non-circular objects with similar functions.
The agitator in top-loading washing machines is responsible for moving the clothing through the water and detergent and is powered by the transmission's output shaft. To achieve a tight fit, the output shaft is generally splined, and the center of the plastic agitator will have a matching spline. When the motor turns, the agitator spins, breaking up any clumps in the laundry.
Washers with horizontal spin cycles work on much the same principle as upright models, except that there are two agitators instead of one. These days, most horizontal spinners have electronic controls which allow them to be programmed to perform different cycles or even be set to automatic mode. In automatic mode, the machine detects when clothes are present in the wash basket and begins spinning the agitators at appropriate times during its cycle.
Agitating clothes in a washing machine removes dirt and other small particles that could otherwise end up in your finished wash. It also helps distribute detergent more evenly throughout the load, helping it do its job better and reducing overdosing. Overall, an agitated wash reduces cleaning time.
There are two types of agitators used in washing machines: magnetic and rubber. Rubber agitators vibrate back and forth within the casing of the machine to break up clumps in the laundry. They work well on solid items such as shirts but not on fluffy things like towels.
