Washers are a practical item that come in a variety of sizes. They can be used to distribute the force of a screw, provide tension or serve as a spacer.
These washers are made from zinc-plated steel for corrosion resistance in wet environments. They can also be made from aluminum or 18-8 stainless steel.
Flat washers
Flat 3 inch washers are small discs of metal that have a hole in the center. They are used to distribute the load of a fastener and prevent it from damaging an underlying surface. They can also help to prevent bolts from loosening over time.
A flat washer can be found in a wide variety of diameters and thicknesses. They can be made from a number of different materials including brass, silicon bronze, stainless steel, zinc plated steel and more.
They can be painted or coated with other coatings to improve their corrosion and rust resistance. There are several different types of coatings available, including electroplating, peen plating and chemical plating.
Steel washers
Steel washers are circular pieces of hardware used to distribute the load of a bolt or screw over a larger surface area. This helps prevent the nut from coming loose or the fastener from being damaged, and it also reduces friction.
Washers can be made from a variety of materials, but stainless steel is often chosen as it has excellent resistance to corrosion and stays shiny for a long time. This is particularly important for structures and products that need to be kept in a constant state of maintenance, such as boats.
Flat washers are circular steel parts with a central hole that span large clearance holes, and are available in a variety of sizes. They can be chamfered on one side or flat on both sides.
Fender washers have a particularly large outer diameter in proportion to their central hole. They are commonly used to spread the load on thin sheet metal, and are named after their use on automobile fenders. They are also used to make a connection to a hole that has been enlarged by rust or wear.
Fender washers
Fender washers are flat washers with a much larger outside diameter than standard flat washers. Their large outer diameter distributes the load applied during tightening of a fastener over a greater area.
This is helpful for fastening sheet metal or a thin material, as it can help spread the load evenly. It also helps extend the bearing surface that a fastener has.
They’re ideal for through-bolting applications that don’t require backing plates and are packaged in various quantities for commonly used fastener diameters. They increase the holding power of hardware installations and reduce point-load stresses on fiberglass, solid wood, plywood and plastics.
Their large outer diameter is particularly useful for securing fasteners in parts that have rusted or worn away. The larger surface area prevents the fastener from driving directly into the corroded surface, which might damage the part or make it hard to work with.
Rubber washers
A washer is a round piece of hardware with a hole in the center, typically placed between a screw or nut and a surface. They are used in applications that require a tight seal and those that are exposed to water, humidity or other liquids.
Rubber washers are a common component in machinery, appliances and household equipment. They offer a variety of benefits, including broad load distribution, reliable spacing, and vibration absorption.
Washers are commonly made from neoprene, but can also be made from other materials such as nitrile rubber (Buna-N), which is resistant to oils, greases, and other liquids. They also resist water and high temperatures, and are able to withstand weathering and UV rays. They can be manufactured for any OD or ID size.
