FAQ
 

What are flat washers and lock washers used for?

Flat washers and lock washers are essential components in fastening systems. Flat washers are flat disks with a hole in the centre. Lock washers are similar but often have a spring-like (or serrated) element for locking. Flat and lock washers serve multiple purposes, including distributing the load, preventing damage to the attached material, enhancing stability, and reducing the risk of thread loosening.
 

What different types of flat and lock washers are there?

Various flat washers and lock washers are designed for specific applications and requirements. Some common types include:

• Flat washers: ISO 7089 and DIN 125 A are the most common flat washers. Hardness 140HV for everything below strength class 8.8, 200HV for critical applications with 8.8, 300HV for applications with 10.9, and for higher than 10.9, different washers must be used.
• Lock washers: Good locking properties (set-locking) for materials up to strength class 5.8; for 8.8 and higher, this is no longer sufficient. Toothed lock washers are also used to establish electrical contact (grounding).
• Spring washers: Capable of locking parts with spring-like properties against settling.
• Disc springs: These conical rings are designed to provide high resilience and compensate for thermal expansion or bolt elongation.
• Sealing washers: These specialised washers create a seal and prevent leakage of liquids or gases.
• Shims: Also known as shims or spacer washers, these are rings with precise thicknesses of 0.1, 0.25, 0.3, 0.5, and 1.0mm. They can be used to fill gaps or create precise distances.
• Backing washers: For a circular shape, we use the term "rings." For a square or rectangular shape, we refer to them as "plates." These plates are large and thick, often used for wood connections.
   

How do flat washers and lock washers influence the strength of bolts and nuts?

Flat washers and lock washers play a crucial role in the strength and reliability of bolted connections. Distributing the load over a larger area helps reduce the risk of fastener failure and material deformation. Certain types of washers, such as spring washers and dish springs, also introduce tension or preload into the fastener. This ensures consistent clamping force and reduces the likelihood of loosening under dynamic conditions.
 

Are there specific applications where certain types of flat washers are recommended?

Different flat washers are recommended for specific applications to enhance performance and ensure proper fastening. For example:

• Spring washers are often used in applications with vibrations, such as in the automotive industry and machinery, to prevent fastener loosening.
• Disc springs are frequently used in critical connections where maintaining high tension is crucial, such as aviation or heavy machinery.
• Sealing washers are ideal for applications requiring a liquid or gas-tight seal, such as plumbing or pneumatics.

How do I choose the right flat or lock washer for my application?

Selecting the right flat washer or lock washer depends on various factors, including the fastened material type, load requirements, operating conditions, and desired level of corrosion resistance. Consult experts or refer to industry regulations and guidelines for valuable insights into making the right choice for your application.

Once you understand the different types and functions of flat and lock washers and how they influence fastener strength, you can make informed decisions when selecting the right components for your needs.
