Washers evenly distribute pressure from a nut or bolt across the surface to which it’s fastened. Washers also protect the surface from damage by separating it from the fastener. In addition, washers help mitigate the threat of vibrations or other environmental factors that may loosen fasteners over time.
Washers have a centrally located hole through which the fastener enters to join with the object. Manufacturers produce washers from several kinds of material, including
Although most applications use metallic washers, nylon washers are growing in popularity as a light-weight alternative. Using nylon washers comes with several advantages, including:
- Excellent insulation properties
- Fireproof properties
- Resistance to friction
- Resistance to corrosion
- Light weight
- Cost effectiveness
Applications across many industries can use nylon washers. For example, medical manufacturers use nylon washers to produce medical instruments, the plumbing industry uses nylon washers to provide durable and reliable seals, and the fire safety industry uses nylon washers to build trustworthy sprinkler systems.

- A huge inventory of materials, including several types of Nylon — in various colors.
Industry Applications for Nylon Washers
Nylon — perhaps most well known as a common fabric in clothing — is actually a strong and highly versatile material that is used in all sorts of demanding industry applications. For instance, the medical industry uses Nylon to make medical instruments; the plumbing industry uses Nylon to provide trustworthy seals; and the fire safety industry uses Nylon in sprinkler systems due to the material’s reliability.
At New Process, we use Nylon to make flat washers with exceptional performance characteristics. We use four different types of Nylon: Nylon 6, Nylon 6/6, Nylon MDS, and Nylatron®.
Nylon 6 is the same material found in fabric, but we use it as a replacement for brass, steel, aluminum, and other metals. Its high strength makes it suitable for gears, spacers, washers, and plumbing parts.
Nylon MDS is a type of Nylon 6 designed for food grade applications. It is also the hardest and strongest type of Nylon, so it is well suited for moving components such as gears, bearings, and wheels.
Nylon 6/6 is a high viscosity Nylon with exceptional strength and temperature resistance. It is often used in chemical and electrical applications.
Nylatron®, a trademark of Quadrant, is a Nylon 6/6 and Nylon MDS blend that is self-lubricating and therefore has very low surface friction. It is used in applications where lubricants are not suitable for various safety or practical reasons.
Most of our clients that use Nylon washers fall into one of the following five industries:
Nylon versus Teflon Washers
Nylon and Teflon are both versatile synthetic polymers that offer higher mechanical strength thresholds and better resistance to friction than traditional metallic substances. Industries across the board use both nylon and Teflon washers in many applications.
However, several noteworthy differences exist between nylon and Teflon. Each material is made using different chemical processes. Nylon forms when an amide reacts with dicarboxylic acid, and Teflon results from the polymerization of tetrafluoroethylene.
This means that nylon and Teflon each have specific physical and chemical properties. For example, nylon is hydrophilic (meaning it tends to mix with water), whereas Teflon is hydrophobic, or water repellent. Therefore, Teflon is a better choice of material when building machinery that requires higher-than-average amounts of lubrication.
Other differences include:
- Melting points: Teflon has a higher melting point
- Electrical conduction: Nylon conducts electricity better
- Chemical reactivity: Teflon reacts less with chemicals
Sourcing Nylon Washers: Stamped Versus Molded
Manufacturers typically use injection molding to build nylon washers. This forms nylon into the desired shape by injecting molten polymers into molds.
However, over the years, nonmetallic stamping has emerged as a popular and cost-effective alternative to injection molding when creating washers. Nonmetallic stamping comes with several benefits:
For most production requirements, nylon stamping (also known as punching) accurately mass produces identical parts at relatively high speeds.
Injecting molten material in molds often leads to the formation of bubbles or other irregularities that affect the production run’s uniformity. In contrast, nonmetallic stamping creates uniform products with little or no visible abnormalities. This is due in part to how the stamping process can shape an entire set of “blank” materials in just one operation.
Faster Turnaround Times
While the output levels of high-speed stamping equipment may vary, it’s possible to attain punching speeds of up to 400 strokes per minute via nylon stamping. Nonmetallic stamping presses can produce as many as 200,000 nylon washers every day, whereas injection molding can only create approximately 25,000 parts per day.
Injection molding may require new molds for each part. However, manufacturers can simply adjust their nonmetallic punch presses to fill the desired order for the customer. This keeps tooling costs down and fills higher order volumes over time. All these factors contribute to increased cost effectiveness for nonmetallic stamping as opposed to injection molding.
One of the most commonly used hardware products is a washer, which is a thin disk typically used for distributing the load of a threaded fastener such as a screw, bolt, or nut. Washers are highly useful as they not only prevent corrosion, but they can be designed for a large range of applications. Furthermore, they come in a wide variety of materials, including aluminum, bronze, steel, copper, and nylon.
Nylon is a synthetic material that can be melted into various shapes and fibers. Known for its versatility, nylon is a popular option for its machinability, chemical and abrasion resistance, and flexibility. It comes in a number of types, including Nylon 6, Nylon 6/6, Nylon MDS, and Nylatron®. Nylon is also a non-flammable material that is non-toxic as well as weather resistant. Because of these properties, nylon is often the preferred material for washers.
Nylon washers are particularly useful as a lightweight, durable alternative to standard metallic washers. Offering excellent insulation and strong adsorption properties, nylon washers are ideal for chemical and electrical applications. These washers are valuable for their ability to maintain their appearance and performance over a prolonged period of time.
Benefits of Nylon Over Metal
Nylon offers many benefits that metal materials cannot match. Two of these benefits include:
- Nontoxicity: Although metallic substances may release corrosive and toxic byproducts over time, nylon is an inherently nontoxic material. For this reason, many producers use nylon washers in food processing equipment.
- High cost efficiency: Nylon washers can be strong and durable, allowing them to resist impacts better than metallic washers. Because of this, nylon derivatives such as nylon MDS are strong candidates for use in machinery components.
Benefits of Black Nylon Washers in the Automotive Industry
In automotive applications, black nylon washers offer a popular alternative to metal-based washers. They provide several advantages:
- Nylon washers weigh less than other washer types while preserving their ability to be tough and flexible. This boosts your vehicle’s fuel efficiency and extends its life span.
- Black nylon washers resist harmful chemicals, meaning that they won’t weaken or corrode from contact with petroleum-based substances or engine oil.
- These washers are also versatile, allowing manufacturers to use them in highly specialized automotive applications.
Using PTFE and Nylon 6 in Plumbing Applications
Polytetrafluoroethylene (PTFE) and Nylon 6 are two nonmetallic materials that provide long-lasting and less expensive alternatives to
standard metal washers in plumbing applications.
PTFE is totally impermeable to water, water-containing substances, oil, and oil-containing substances. For this reason, it’s an ideal choice for plumbing applications, and manufacturers of plumber’s tape (also called thread seal tape) use this material in their products. PTFE also provides good thermal and electrical insulation, and it has a low coefficient of friction.
The impact strength and energy absorption attributes of Nylon 6 increase with moisture absorption. However, exposure to moisture may also decrease its stiffness and tensile strength. However, when plumbers properly account for these negative effects, Nylon 6 washers benefit applications including showerheads and faucets.
