A washer is a piece of circular hardware that distributes the force of a screw or nut in an even fashion. Additionally, washers can reduce friction, stop corrosion or leaks, maintain tension, and act as a spacer. They are required in the majority of construction projects because of their numerous applications. However, it can be thicker than it seems to select the best type of washers and bolts (Unterlegscheiben und Schrauben) for a project.
The most widely used materials for washer production are stainless steel and galvanised carbon steel. Although stainless steel is more corrosion- and rust-resistant than carbon steel. Zinc, brass, copper, and iron are additional metal washers. Specialty washers are also available, including rubber, ceramic, plastic, and phenolic screw washers (Schrauben Unterlegscheiben).
Plain washers, spring washers, and lock washers are the three main categories of washers. There are additional specific forms that are used for certain reasons within each of these categories.
- Plain Washers (Einfache Unterlegscheiben)
The most popular type of washers is plain washers, often known as flat washers. They disperse force and safeguard the item that the screw or nut is attached. A simple bolt with washer (Schraube mit Unterlegscheibe) can be used to make up for a hole that is too large for the fastening.
- Flat Washer (Flache Unterlegscheibe)
The flat washer is what most people envision when they think of a regular washer; it is also referred to as a Type A plain washer. They are flat and circular, vary in thickness, and have a central hole for a bolt. It is used to adjust a hole’s size or disperse force. It is suitable for any usage.
- Fender Washer (Kotflügelscheibe)
Fender washers are flat washers with a relatively wide outside diameter and a small hole that are frequently used on automotive fenders. In this usually thin metal is used to transfer force over a vast surface area.
- Torque Washer (Drehmomentscheibe)
A torque washer stops an accompanying bolt from spinning while tightening a nut with its square hole and outer prongs. In woodworking tasks, it is paired with a carriage bolt.
- C-Washer (C-Unterlegscheibe)
When compared to a flat washer, a C-washer features a slot that is cut out of the centre hole to produce a “C” shape. It is used wherever it would be necessary to replace, modify, or remove a washer without removing the fastener.
- Finishing Washer (Finishing-Waschmaschine)
A finishing washer, also called a countersunk washer, has a sunken top intended to trap the fastener. When fastened with countersunk screws, it creates a flush surface.
- Spring Washers (Federscheiben)
Due to their axial flexibility, spring washers can move with vibrations, preventing unfastening or loosening as a result of those vibrations. They improve a joint’s ability to stretch.
- Belleville Washer (Belleville-Waschmaschine)
A Belleville washer, also known as a conical spring washer, has bevelled sides that can withstand significant force with minimal bending. It is used in thermal expansion-related applications.
- Crescent Spring Washer (Halbmond-Federscheibe)
Crescent spring washer is also known as curved spring washers. These are seemed to be flat washers that have a little curved to exert minimum pressure and preserve flexibility. It is utilised to absorb movement.
- Dome Spring Washer (Kuppelfederscheibe)
These are just like Belleville washers but have rounded sides. These are utilised whenever there is a need for a crescent spring washer but it should be amended to make a flatter surface.
- Finger Spring Washer (Fingerfederscheibe)
These types of washers have three different curved flanges. It is utilised for dampening noise and vibrations.
- Wave Spring Washer (Wellenfederscheibe)
These washers are curved in two different directions for making a wave-like shape. It is utilised mostly as spacers or cushions.
