  • For nylon washers visit https://www.superiorwasher.com/washers/93/Nylon.html or call Superior Washer at 888-592-2570.

    Nylon washers are spacing components that are meant to be used between the head of a fastener, such as a bolt or a screw, and the surface in which that fastener is installed. They can also be used between a nut and an installation surface. Whether used alone or stacked, they’ll help to distribute load or force.

    Without a nylon washer, the pressure within a fastener assembly could cause an installation to warp or wear. If that occurs, the head of a fastener or nut could become embedded in a surface, making tightening and loosening difficult and compromising the security of a fastener assembly.

    A nylon flat washer helps to prevent this from happening, thereby contributing to easy maintenance and the longevity of a fastener installation.

    By virtue of their material attributes, nylon washers can incorporate a lot of other advantages into an application. Nylon is a synthetic polymer that exhibits durability, resistance to many different chemicals, abrasion, corrosion, mold and mildew, fading, and friction.

    Nylon will also stand up to moderately high temperatures and will melt rather than burn. As a material, it was originally developed for military applications, and while it has been widely used in a range of commercial and industrial products since its first production, it’s still found in many defense uses. For all of these properties, natural nylon washers are good general purpose washers when a metal washer isn’t suitable.

    Natural nylon washers are typically white or off-white, although the material takes well to various dyes and exhibits considerable colorfastness. Black nylon washers and nylon washers in other colors are readily available if a darker or more subdued washer is needed in an installation.

    It’s not unusual to find black nylon washers employed in structures or equipment where a consistent color esthetic is needed, such as in household appliances and furnishings, automotive interiors, and electronic housing.

    Nylon flat washers are fairly economical and easy to produce, and can be stamped in many different sizes. Small nylon washers may be needed for intricate equipment and assembles, while large nylon washers can be found in various structures and industrial equipment, performing tough load-bearing functions.

    Whether small or large nylon washers are in use, their stability and resistance means they’re versatile and useful components.

    Although nylon flat washers are among the most common types of nylon washers, non-flat locking washers and conical washers can also be made from nylon. These washers will provide a spacing function, but they are mostly used for locking or shock absorption purposes.

    Nylon fender washers are nylon flat washers, but they feature a notably larger exterior diameter in comparison to their exterior diameter. Nylon washers also include nylon shoulder washers, which feature a shank and are used for insulation and vibration reduction, as well as sealing functions.

    When sourcing nylon washers for any application, it’s important that your chosen provider be reputable. The integrity of the nylon used to create the nylon washer determines its reliability and performance in its end application.

    For this reason, it’s beneficial to order washers directly from a well-known washer manufacturer that can assure the quality of the raw material used in the stamping process.

    Superior Washer & Gasket Corp. is a leading source of washers, shims, and small stampings made from all different types of materials. Nylon flat washers are among their vast inventory of washers, which are available in U.S. standard and metric sizes.

    The nylon used to create these washers is genuine, high performance, industrial grade nylon, which can be stamped according to common as well as custom specs. Superior Washer’s nylon washers can be purchased in custom quantities and are also available in quantity packs of 25, 50, and 100 counts.

    The extension is to limit torque, it is almost impossible to show this demo on a regular 19mm bolt with very powerful impact unless you can find a stuck crank bolt which can be tough if you are using 1000ft-lbs impact guns. If you would like to see the weight comparison of sockets they are in this video: https://www.youtube.com/watch?v=SGbYcLobC3M .
    Here is my homemade 19mm heavy crank pulley bolt impact socket from this video https://www.youtube.com/watch?v=4c5uNnggwZU works great…but sometimes doesn’t work (as shown at end of video) but I read the same with the real crank pulley sockets like the Bluepoint CBSM19 or Lisle 77080 they don’t always work…so sometimes the bolt must be so tight you just need a bigger impact wrench or heat.
    But I bet these heavy sockets would help 99 percent of the time unless you have a really weak impact then nothing will help. The lisle is probably made the best because it is one diameter all the way to the front. You could make a heavy socket for ANY size nut or bolt.
