Plain Washer

Plain washers are basic pieces used when bolting things together. They do three main jobs: spread pressure from the bolt, reduce rubbing between parts, and stop surfaces from getting scratched. They’re just flat rings with a hole in the center where the bolt goes through. This simple design helps balance the force when tightening joints.

In mechanical set-ups, plain washers can act as spacers, help reduce vibrations, or work as insulation. Their basic design means they can be used in lots of different situations, whether it's in cars or construction.

They come in standard sizes and can also be made to order. This allows them to fit different bolt sizes and material thicknesses. As a basic part in hardware kits, plain washers make fasteners last longer and keep structures strong. They're an affordable option for both industrial work and DIY projects.

Features

Plain washers are handy, affordable, and get the job done. Their main job is to keep bolts or screws from shaking loose from vibrations or heat expansion. They spread the pressure evenly, which helps protect softer materials from getting crushed or rusting out.

Unlike specialized washers, you don’t need special tools to install plain washers,just pop them in place. That saves time and labor costs. They work with most screws and bolts, so you’ll find them used everywhere from cars to furniture.

They’re made to match ISO or DIN standards, so you know they’re consistent in thickness and hole alignment. In industries where safety’s critical (like construction or machinery), plain washers act as a backup to keep joints from failing. Plus, they’re lightweight, so they won’t bulk things up in weight-sensitive stuff like planes or gadgets.

Material

Q:  What materials are available for plain washers and how do I choose the right material?

A: Plain washers usually use carbon steel, stainless steel, brass, aluminum or nylon and other materials. Carbon steel is strong and low cost, which is why most people choose it for everyday factory work.

Stainless steel (like 304 or 316) won’t rust much,works well in wet places, salty air, or around chemicals. Brass doesn’t stick to magnets and conducts electricity, so they’re good for wiring jobs. Nylon’s lightweight and blocks electricity,helps prevent shorts.
