Product Information

Countersunk washers : Countersunk washers make installing flat or oval head countersunk screws flush with the part surface. They’re commonly found in consumer products like cabinets and furniture. A plain washer type with integral cylindrical sleeve. Used as a barrier between differing metals and as a seal. [21] This term is also used for electrically insulating grommets. [22] Fender washers : Fender washers are flat with a small hole and a large outside diameter. This type of plain washer can distribute loads across a larger surface area than flat washers.

Crush washers are soft metal fasteners composed of aluminum or copper. They seal fluid or gas connections in internal combustion engines and hydraulic systems.A washer is a component that works with a fastener, such as a bolt, screws, or nuts, to prevent it from loosening. It also spreads the load from the fastener head over an expanded area. Washers can be plastic or metal. A washer made of soft metal such as aluminium or copper. Used to seal fluid or gas connections such as those found in hydraulic systems and in internal combustion engines. The origin of the word is unknown. The first recorded use of the word was in 1346; however, the first time its definition was recorded was in 1611. [1] Installing crush washers is simple, but attention to detail is critical. The surfaces that the crush washer will be installed between should be clean and free from debris, rust, and other contaminants that may compromise the integrity of the seal. The crush washer should be inserted by hand, and its edges should line up with the fasteners and not go over them. Advantages of using Crush Washers A flat annulus or ring, often of metal, used to spread the load of a screwed fastening. Additionally, a plain washer may be used when the hole is a larger diameter than the fixing nut. [2] [3]

Phosphating – A resilient, but abrasive surface is achieved by incorporating a zinc-phosphate layer and corrosion-protective oil. A crush washer may sound like an unusual item, but it is one of the essential components in industries that require a fastening mechanism. It is a specialized type of washer commonly used in the automotive and plumbing industries. A crush washer is constructed with a material that is softer than the material being fastened. It is fitted between the two metal surfaces and is compressed to create a watertight or airtight seal. It prevents leakage and ensures uniform compression and a stable joint. In this blog, let’s explore this small but crucial component, its uses and applications. What is Crush Washer? The American National Standards Institute (ANSI) provides standards for general use flat washers. Type A is a series of steel washers at broad tolerances, where precision is not critical. Type B is a series of flat washers with tighter tolerances where outside diameters are categorized as "narrow", "regular" or "wide" for specific bolt sizes. [27] Fasteners, such as screws, nuts, and bolts, hold these pieces together. But these fasteners can sometimes put too much pressure on the object they are fastening. Washers are usually metal or plastic. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to brinelling after the torque is applied. Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces. They may also be used in rotating applications, as a bearing. A thrust washer is used when a rolling element bearing is not needed either from a cost-performance perspective or due to space restraints. Coatings can be used to reduce wear and friction, either by hardening the surface or by providing a solid lubricant (i.e. a self-lubricating surface).

Rubber or fiber gaskets are washers used to prevent water leaks in taps. They’re not the traditional machine fasteners, and while they may look similar, washers and gaskets have different designs and functions. Fluorescent light". Popular Science. Bonnier Corporation. 186 (6): 117–118. June 1965. ISSN 0161-7370. Anyway, the theory is that as a filter of this type gets used, more & more of the holes trap particles of dirt and thus more of the larger holes get partially or fully filled. If you graphed this out over time you would see that the flow starts to become more restricted but the average particle sizes getting through also reduces.

Some washers are specifically designed to absorb vibrations. These washers are usually not made of metal. Instead, they are a softer fastener made from plastic, rubber, or urethane. Bolt : A bolt is a threaded fastener that always accompanies a nut. A bolt comprises a head, cylindrical body, and threads along its length. Phenolic – The material has good electrical insulation, is lightweight, tough, has low moisture absorption, is heat resistant, and is resistant to chemicals and corrosion. Phenolic washers are substitutes for flat metallic washers in cases where electrical insulation is required. Phenolic washers are stamped out of large sheets of the phenolic material. The term "phenolic washer" is sometimes used for stamped washers from laminated materials such as paper, canvas, and Mylar. Paul Green (2007). The Mechanical Engineering Drawing Desk Reference: Creating and Understanding ISO Standard Technical Drawings. Lulu.com / CreateSpace. Washers, p.205. ISBN 9781847531155.Anchor fasteners : Anchor fasteners connect structural and non-structural elements to concrete or other materials in the building industry. These fasteners take a position by drilling a hole larger than the fastener diameter in the base material. Type and form [ edit ] A plain washer and a spring washer are placed on a bolt between the nut (on the threaded end) and the bolt head. Shoulder washers : Shoulder washers work in electrical equipment to insulate fasteners or shafts. As a result, non-conductive materials form the make-up of shoulder washers. As a tip, if you’re in a humid climate, don’t use it. A flat washer with a particularly large outer diameter in proportion to its central hole. These are commonly used to spread the load on thin sheet metal, and are named after their use on automobile fenders. They can also be used to make a connection to a hole that has been enlarged by rust or wear. In the UK, the name originally comes from the size of the old British penny. In the UK, most industries refer to all large OD washers as penny washers, even when the OD is as much as twice the size of the old penny. We’ve highlighted some functions of washers, but we’ll now discuss them in full detail. Washers distribute load :

Many different types of nails are named after the jobs they’re used for, making it simple to find the right one. In addition, they usually have characteristics specific to the materials or applications in question. Plumbing fixtures – Crush washers make leak-free connections between pipes and valves, ensuring tight fittings. Other types of washers keep liquids and water out. They’re commonly used to create a waterproof seal in water pipes and connections. Liquid-sealing washers are made of a soft substance that may press entirely against the object’s surface.They then insert the anchor to a depth known as embedment depth. Mechanical anchor fasteners and chemical anchor fasteners are the two most common types. Conclusion Plain washers, which spread a load, and prevent damage to the surface being fixed, or provide some sort of insulation such as electrical To appreciate what crush washers are, we’ll need to understand the concept of washers in general. So, what are washers? What Are Washers?
