Selecting the Appropriate Washers, Nuts and Bolts for Use

A number of items are needed when undertaking maintenance and repair works. Restoring an old car for instance requires having fasteners of varied types and sizes. Such action can help someone in attaining faster completion of the project at hand while affording the restored vehicle a refined appearance. Tornirap provides fastening solutions to cater for the numerous requirements clients have within the automotive and other industries.




The term washer refers to a thin plate with hole, normally utilized for distributing the load of a screw, nut or other type of threaded fastener. This gadget can also be used as a spring (wave washer, Belleville washer), spacer, wear pad, locking device, preload indicating gadget and for reducing vibration (rubber washer). The outer diameter of this industrial accessory usually measures about twice its inner diameter’s width. Metal or plastic is employed in their construction. Bolted joints of high quality require the hardened steel versions for preventing loss of pre-load as a result of brinelling, upon application of torque. Utilizing a washer also helps to prevent galvanic corrosion, especially through insulation of steel screws from aluminum surfaces.


A nut is a form of fastener with threaded hole mostly utilized opposite a mating bolt for fastening together a stack of parts. The friction caused by their threads, some slight bolt-stretch and compression of the parts keep the two partners together. A host of locking mechanisms can be applied where rotation or vibration may lead to nut-loosening. This includes adhesives, nylon inserts, safety pins or threads of slightly-oval shape. Hexagonal is the most common shape for reasons similar to those of the bolt head. Six sides offer appreciable angle-granularity when using tools, but having more corners would mean being more vulnerable to round-offs. This type of fastener comes in other customized shapes as well. Tornirap stocks a variety of nuts suitable for a host of industrial tasks.


The term bolt refers to a kind of threaded fastener which features an external male thread. This industrial ware, oftentimes confused for a screw, is utilized for assembling two unthread components using a nut. Screws are by contrast applied in conjunction with components, with at least one having its own internal thread that can even be formed by installing the screw itself. A lot of threaded fasteners may be described by either term screw or bolt, depending upon their application, with the latter being often used for making a bolted joint. This combines axial clamping force by the nut with dowel-action of the bolt, which pins the joint against shear forces acting sideways.
