How to Properly Use Washers and Why They Matter in Fastening

Washers: The Unsung Heroes of Fastening Done Right

Let’s talk about something that often gets overlooked but can make or break your next DIY project—washers. These little rings of metal or plastic might not seem like much, but they play a huge role in keeping things tight, secure, and long-lasting. Whether you're building a deck, fixing a leaky tap, or assembling a new outdoor shed, washers deserve a place in your toolbox.

What Does a Washer Actually Do?

Think of a washer as a bodyguard for your screws and bolts. It distributes pressure evenly, keeps things from loosening over time, and stops damage to surfaces. Without a washer, a bolt or screw can dig into materials, weaken connections, and create a mess down the track.

Ever noticed how screws and bolts tend to wiggle loose over time, especially on high-vibration surfaces like furniture or machinery? That’s where washers step in. They prevent loosening by absorbing some of that movement and keeping everything locked in place.

Types of Washers and Where to Use Them

Not all washers are created equal. Choosing the right one can be the difference between a job done well or one that falls apart too soon.

Flat Washers

The all-rounder of the washer world. Flat washers provide a smooth surface to distribute pressure and prevent damage to delicate materials. Use them when working with softwoods, plastics, or when extra support is needed under a nut or a bolt head.

Spring Washers

Designed to fight against loosening, these washers are great in places where vibration is a concern, like with machinery or furniture that sees a lot of movement. Ever had a chair leg that kept coming loose? A spring washer could be the fix.

Mudguard Washers

These have a larger outer diameter, making them perfect for spreading force across a bigger surface area. If you're dealing with thin sheet metal or softer materials, mudguard washers keep bolts from pulling through.

Square Washers

A square washer is like a standard flat washer for all types of threaded fastening screws, but its outer shape is square instead of round. This handy washer allows the weight to be distributed on an equal surface area.

Why Skipping Washers Could Cost You

We've all been tempted to take shortcuts on a project, but skipping washers can cause long-term trouble. Without them, bolts can loosen, wooden surfaces can crack, and metal materials can erode from repeated pressure. Washers may seem like a small detail, but they ensure fastenings last longer and perform the way they should.

Picking the Right Washers for Your Project

Choosing the right washer depends on what you're working on. If you're building outdoor furniture, go for stainless steel washers to prevent rust. For electronics or delicate surfaces, nylon washers protect against scratches and electrical conductivity.
