Design Engineer's Application Guide Fasteners

Our fasteners are designed to work for just about every application.

However, in certain instances, a particular screw, nut, washer or rivet is the ideal choice for your task. To help you choose the fastener you need, we’ve put together this guide. Materials are important when making your choice, so we also recommend our Fastener Material Selection Guide.

With fasteners ranging from nylon thumb screws and wing nuts to solid rivets and finishing washers, we’re here to make your job easier. That’s why we also encourage you to download free CADs and try before you buy with free samples.
