What Are Washers?
Washers are thin plates, typically made of metal or plastic, with a hole in the center. They are used in conjunction with screws, bolts, or nuts to distribute the load, prevent damage to surfaces, and improve the stability of the fastened joint. By reducing friction and providing a more even surface, washers help prevent loosening and wear.
Types of Washers
There are many types of washers available, each serving a specific purpose. Three common types you might encounter are standard washers, penny washers, and square plate washers.
Penny Washers
Penny washers are named for their large, flat surface area, resembling the size of a penny. They are typically used to spread the load of a screw over a wider area, which is particularly useful when fastening soft materials like wood. Penny washers reduce the risk of the screw pulling through the material and provide added stability.
Square Plate Washers
Square plate washers are designed with a square shape instead of the traditional round form. This design prevents rotation under pressure and can offer higher resistance to torque. Square plate washers are often used in structural applications where stability and load distribution are critical. Their shape allows them to fit snugly against corners and provide extra support.
Why Washers Are Important
Using the right washer can significantly impact the longevity and effectiveness of your assembly. Washers can:
- Prevent surface damage by distributing pressure
- Reduce loosening due to vibration
- Enhance load-bearing capacity
- Improve the alignment of fasteners
By understanding the differences between penny washers and square plate washers, you can make informed decisions for your projects.
Everyday Applications
Washers aren’t just for industrial use. They appear in many everyday applications, such as furniture assembly, home repairs, and DIY projects. For instance, when securing a wooden shelf, using a penny washer can prevent the screw from damaging the wood, while square plate washers can be useful in more structural elements like timber framing.
Tips for Selecting the Right Washer
- Material Compatibility: Match the washer material with the screw or bolt to avoid corrosion.
- Size Matters: Ensure the washer diameter fits the screw and the surface area needed.
- Consider the Load: Heavier applications may require larger or square plate washers.
- Environment: Outdoor or humid applications benefit from stainless steel or corrosion-resistant washers.
