Nylon Flat Washer, ANSI, #4, 0.125" ID, 0.375" OD, 0.04" Thick (Pack of 100) Feature

  • Flat Washers are an economical choice
  • Nylon 6/6 is suitable where non-conductivity, corrosion resistance, and cost are important considerations
  • Size Name corresponds to matching screw or bolt size
Standard flat washers are an economical choice when your application calls for spacers, shims, or re-enforcements with nominal dimensions only.

Nylon 6/6 is a general purpose thermoplastic with outstanding resistance to organic chemicals, acids and alkalis. Nylon wears well against other surfaces; it is readily machinable and may be milled, turned and cut with conventional machine tools. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Tensile strength of this material is 12,000 psi (pounds per square inch).

Wave Flat Washer, 3 Wave, 18-8 Stainless Steel, Round Shape, USA Made, #5 Bolt Size, 0.128" ID, 0.188" OD, 0.005" Thick (Pack of 25) Feature

  • Made in the USA to strict quality standards
  • Wave Washers are used as springs where space is tight
  • 18-8 Stainless Steel is the most common corrosion resistant Stainless Steel used in Flat Washers
  • Wave washers are one of the best mechanical methods of maintaining joint tension
  • 3 Wave Washers have greater strength than 1 Waves, and function in tight spaces
Wave Flat Washers are designed to replace a traditional spring, where there isn't enough room for the compression and extension of a regular spring. They also act as a locking washer, replacing toothed or split spring washers. Also known as Belleville Washers, these products have a high load capacity with a small deflection area, making them perfect for use in small products and places. Manufactured from Full Hard 300 series Stainless Steel.

Made in the USA. These flat washers are produced in the USA for excellent quality conformance. One of the significant differences between less expensive imported products and ours are the way we stamp. Many cheap imports are produced on gang dies that produce 10 or more washers per stroke of the press. Using such a large die means that the individual washer sets are not adjustable - when the punch wears, the dimensions change and there is no way to fix this as the press produces washers, leading to a large variation in the finished part.

Materials available in many other countries are not as consistent as the domestic steels we use, which gives the imports a cheaper cost, but can lead to failures and inconsistencies when the products are used. The Defense Federal Acquisition Regulation Supplement (DFARS) was created to address this problem. Our materials are DFARS compliant although we do not supply the certification except on special order.

Beveled FW Flat Washer, 18-8 Stainless Steel, Round Shape, USA Made, #10 Bolt Size, 0.203" ID, 0.500" OD, 0.094" Thick (Pack of 10) Feature

  • Beveled Flat Washers are machined on Lathes, and feature a large bevel or chamfer on the top side
  • The top bevel allows easier installation in tight spaces, and the part looks like a design feature of any product it is used on
  • 18-8 Stainless Steel has a nice surface finish and is the most commonly used corrosion resistant material used
  • Chemical, Marine, outdoor, power transmission are a few industries where these parts are used
  • Made In USA for excellent quality conformance
Beveled Flat Washers (also known as "Williams Washers") are turned from solid bar, and feature a large bevel or chamfer on the top outside edge. Originally manufactured for the dual purpose of protecting assemblers from the sharp edges that are possible with a stamped washer, and also to allow them to orient the washer quickly, these washers have gained popularity for other purposes. Used in construction and architectural applications as an interesting visual part of the design, they offer the strength that is provided by their thickness. A small inner diameter provides a tight fit to bolts, rods, and studs, and eliminates most shifting and vibration of the washer. General industrial, marine, power transmission, and agricultural uses are popular.

Manufactured on Lathes from Type 303 Stainless Steel bar, this washer is 100% USA made. Available from #10 through 1-1/4" Bolt Size.

  • Made in the USA to USS (United States Standard) dimensions
  • USS are larger and looser fitting than the SAE pattern washers
  • 18-8 Stainless Steel is the most common corrosion resistant Stainless Steel used in Flat Washers
  • USS pattern washers are large washers which distributes the load over a wide area - perfect for low strength and thin materials being clamped
  • One of the most common general purpose flat washers for MRO applications
SAE (Society of Automotive Engineers) and USS (United States Standard) washers are generally thought of together as the standard low cost option for flat washers in general usage. SAE washers are smaller in all dimensions than USS, so they don't distribute loads as well as the USS. However, they fit in many places that don't have room for the larger USS. These washers are generally manufactured out of low carbon steel with a zinc plating. We offer from stock a finely made washer out of 300 Series Stainless steel (302,303,304), which offers a combination of strength and corrosion resistance, or Type 316 Stainless Steel which offers a bit less strength, but more corroision resistance. Type 316 is specified in most marine and salt water environments, as well as most food processing and chemical plants.

  • Dress Washers are turned on Lathes so the sides are completely straight, and are used in exposed applications for a finished or dress appearance.
  • Used in any application where the washers are part of the product design, and are visible to the user of the device
  • 18-8 Stainless Steel is a good looking (bright and shiny) material with good surface finish and corrosion resistance
  • Used on medical equipment, exercise equipment, instrument panels, etc.
  • Made In USA for excellent quality conformance
Dress flat washers are named because they are used to dress up a product. Machined from round stock, they present a finished appearance from all sizes, and front and back. There is no die break on the sides of these washers, as they were produced in Lathes rather than stamped from a coil. Used on faceplates, excercise equipment, high quality architectural hardware, medical and optical instruments, and anywhere that a good looking strong product is required. Extra thick material is used to increase both the strength and the appearance. 303 Series Stainless Steel provides both strength and corrosion resistance. Washers are slightly magnetic from the machining process. Made in the USA.

  • NAS620 is one of the smaller pattern general use flat washers
  • 18-8 Stainless Steel is the most common corrosion resistant Stainless Steel used in Flat Washers
  • The sizes listed in this specification cover most industrial and military uses
  • Tight tolerances allow use in precision applications
The 3 most popular Military Specification Flat Washers that we offer are MS15795, AN960, NAS1149, and NAS620. These specifications were originally formulated by the Armed Forces of the USA to standardize fasteners being used on military equipment. Over time they have become a popular choice for designers in all industries and programs. All of these specs call out the same material - a 300 series Stainless with passivation. The differences are in the manufacturing tolerances, and the different dimension traits. the first choice should be the MS15795 series, which has the largest OD, and the largest hole diameters. Second choice should be the NAS1149 series. This has a smaller outer diameter, and a tight tolerance on the inner diameter as well as the thickness. AN960 offers an equal to the NAS1149 but with a larger tolerance on the thickness. NAS620 should be the last choice - this series has the smallest outer diameter, and the widest range of thickness tolerance.
