Our washers find applications across various industries, including Mechanical, Chemical, and Petrochemical. Each type of washer offers distinct capabilities to suit specific design requirements and applications. Some specialised washer types are tailored for specific purposes. Washers, typically disk-shaped with a central hole, serve the purpose of joining two components, such as a bolt and a screw. They are crafted from various metals and serve diverse functions, including load distribution, spacing, fastener locking, vibration reduction, and corrosion prevention.

Washers can be categorised into three main types: Plain washers, the most common type, are employed in a wide range of industries. They are used to distribute loads, protect surfaces, and often serve as electrical insulators. Plain washers come in various subtypes, including wall washers, fender washers, and torque washers.

Spring washers, another vital type, offer axial flexibility. They are equipped with spring characteristics that help reduce wear and tear during operation. Spring washers find applications in diverse industries, such as aerospace and transportation, including actuator systems like flight control and landing gear.

Locking washers, a subtype of spring washers, are used to secure nuts, bolts, screws, and other components during machinery operation. These washers are widely employed in automotive, aerospace, and household appliances.

At Deltron Alloys, we uphold the highest standards in washer manufacturing and are dedicated to providing top-notch service. Our products are meticulously packaged using various methods, including plastic wrapping and wooden boxes, ensuring safe delivery to our valued customers.
