    Extra Thick Fender Washers Price in India : $0.63 (0.63/ea) to $1.22 (1.22/ea)

    Thicker Flat Washers with a Larger Outside Diameter

    Fender Washers are used to prevent pull-though and provide a greater bearing surface under the fastener. This prevents nuts, bolts or screws from pulling through the base material. Extra Thick Fender Washers are much thicker than a standard Fender Washer (For Example a 1/4" x 1-1/4" Standard is 0.050 inches thick, whereas an Extra Thick is Max 0.125 - Min 0.100 inches). They can also be used to fasten holes that are too large or have rust around the edges.

    EXTRA THICK STAINLESS STEEL FENDER WASHERS

    18-8 Stainless Steel


    Fender Washers are used to prevent pull-though, and provide a greater bearing surface under the fastener. This prevents nuts, bolts or screws from pulling through base material. Fender Washers are distinguished from standard flat washers by their significantly larger outside Diameter (or OD), which creates a larger surface area on the fastener assembly, allowing it to withstand more force. Fender Washers are commonly used to distribute load force on sheet metal, and gain their name from the use on car fenders. In the UK, Fender washers are also known as Penny Washers.

    304 Stainless Steel Fender Washers offer a durable and long lasting assembly due to the corrosion resistant properties of Stainless Steel. Extra Thick Fender Washers are significantly thicker than a standard Fender Washer (For Example a 1/4" x 1-1/4" Standard is 0.050 inches thick, whereas an Extra Thick is Max 0.125 - Min 0.100 inches).

    Military Standard Flat Washers

    Fit Military Specifications | 800 Series

    The overriding characteristics of military flat washers compared to commercial products is the extensive inspection and lot tractability, guaranteeing the chemical, physical and dimensional qualities. While commercial fasteners may look similar and happen to pass many tests given MS washers, the commercial fasteners lack the pedigree of guaranteed quality for chemical, physical and dimensional aspects that users who order MS flat washers rely on.

    800 Series Military Standard Flat Washers are available in corrosion resistant 18-8 Stainless Steel. MS - Military Standards.

    AN960C 900 SERIES FLAT WASHERS

    18-8 Stainless Steel Flat Washers in Airforce & Navy Aeronautical Standards


    Flat washers are positioned beneath the head of a screw or bolt on an assembly. They are used to distribute the force of an assembly over a wider area. A flat washer is a round outer diameter thin plate with a center hole (inner diameter) punched to the size of the bolt or screw size. Flat washers are normally used to distribute loads of threaded bolts, screws and nuts evenly as the fastener is tightened.

    AN960C 900 Series Flat washers are available in standard and light (L) thicknesses. AN960C Flat Washers 18-8 Stainless Steel are corrosion resistant and are used in military applications. AN 900 series flat washers meet standards for the Navy and Airforce, which is where the washers receive the "AN" name.

    316 AND 316L STAINLESS STEEL FLAT WASHERS

    316 and 316L stainless steel are a molybdenum-bearing austenitic stainless steel. 316 series stainless steel contains more nickel compared to 304 stainless steel which gives it a better corrosions resistance compared to 300 series stainless steel. 316 stainless steel can withstand such harsh environments while being exposed to water (fresh and sea), chloride corrosion, and other chemicals such as sulfuric, phosphoric and acetic acids. It also offers good strength and creep resistance while being exposed to subzero temperatures while still maintaining mechanical and corrosion resistances.

    Stainless Steel Bonded Sealing Washers / Stainless Steel Bonded Sealing Washers Suppliers / Stainless Steel Bonded Sealing Washers Largest Stockist in India

    PRODUCT: 3/8 ID x 7/8" OD 316 Stainless Steel Sealing Washer. 20 Gauge 316 Stainless Steel with 0.076" Bonded EPDM Rubber Seal. 4000/Box. Price/Box. (leadtime 1-3 business days)

    APPLICATIONS: Marine, saltwater or anywhere corrosive or where 316 stainless is needed. Sealing and flashing; metal roofing and siding applications etc. Fits tightly to 3/8" fasteners, screws etc.

    MATERIALS/CONSTRUCTION:
    ASTM grade 20-Gauge (~0.040") 316 Stainless Steel
    Black EPDM Rubber 70 durometer hardness, thickness about 0.076", meets ASTM D2000.
    Overall thickness about .150" before compression;
    Available compression about 0.030".
    Made in India.

    BONDED SEALING WASHER MATERIALS: Standard thickness is 0.065 for Metal backed washers, and 3/32" (0.093") for plain rubber washers. EPDM
    (Ethylene Propylene Diene Terpolymer) is an excellent, low-cost ozone and weather resistant elastomer which possesses superior aging characteristics. It is also extremely effective when application requirements dictate heat resistance up to 275º F (intermittent), 212F continuous. Use of EPDM in direct contact with petrochemicals is not recommended. For construction applications where the primary hazards are ozone ultraviolet radiation and temperature extremes, EPDM is the consistent elastomer of choice. EPDM Rubber Datasheet
    NEOPRENE
    (Polychloroprene), one of the earliest and perhaps best known, of the man-made elastomers is still one of the most versatile facing material for sealing and cushioning washers. Recommended for alkaline and acid salt solutions and aldehydes such as formaldehyde -65°F to 250°F. It is highly resistant to sunlight ozone weathering and aging while enjoying good memory and elasticity. Although its particular strength lies in its resistance to petrochemicals and certain other chemical families Neoprene is a generalist - performing well in a myriad of applications. When direct contact with petrochemicals is of greater concern than direct U.V., Neoprene will do the job. SILICONE: High Temperature Red Silicone is available by special order (order minumums apply). Suitable for 500F (260C) intermittent and 437F (225C) continuous.
    Substrate Backing Metal Materials: Standard thickness is 20 gauge, others are available by special order GALVANIZED STEEL provides excellent strength characteristics and possesses greater corrosion resistance than a common commercial zinc-plated bolt or screw at the lowest possible cost.

    STAINLESS STEEL (Austenitic 300 Series or 18-8/A2) combines the optimum corrosion resistance and lowest cost available in a premium material. Its use is indicated wherever stainless fasteners are required or when a corrosive environment would compromise lesser metals.

    316 STAINLESS STEEL (Austenitic 300 Series with Molybdenum/A4) provides the highest corrosion resistance available in standard production materials. due to its higher cost it is specified only in the highest corrosion marine or industrial environments. BONDED SEALING WASHER FEATURES:

    Where sealing properties are required, the conical design directs the flow of the elastomeric portion toward the problem areas. Where cushioning or vibration presents a problem, our full-face elastomeric material affords 100% protection.

    Features Include: Quality elastomeric compounding to meet specifications for elasticity, memory, temperature extremes, chemical, ozone, and sunlight-resistance.

    Conical design directs flow of facing materials to form a seal conforming to both fastener and sealing surface.

    Full-face design cushions fragile surfaces and minimizes vibration.

    Inside diameter sizes for #4 diameter screw to 1-1/2" diameter bolts and corresponding metric range.

    Typical Dimensions: Metal Thickness is 20 Gauge / ~ 0.030 mils, and rubber thickness is 0.066" nominal. Washer assembly is coined to created a total thickness of 0.120 to 0.140, depending on washer size (before torque is applied). Inside diameter of rubber washer is designed to seal tightly to screw.

    BONDED SEALING WASHER INSTALLATION GUIDE:

    SEALING IN. . . OR SEALING OUT 
    When installed in a sealing application, the materials in Sealing Washers compress against either a flexible or an inflexible surface to permanently seal in or seal out any operating environment, whether natural or industrial. Facing materials are engineered to provide optimal resistance to weathering from ozone, ultraviolet light and/or chemical agents.

    CUSHIONING AND VIBRATION CONTROL 
    As the washer is compressed and fastened against a substrate, the facing material serves as a permanent cushion. This feature protects the substrate from installation damage (spinning fastener and/or torque) and from vibration damage during the product's life cycle.
