So, you’ve got a project that requires securely joining two pieces of wood or metal together. You’ve heard about v clamps but aren’t quite sure what they are or how to use them properly. No worries, this comprehensive guide will tell you everything you need to know about v clamps, from what they are and how they work to tips for installing and using them for various applications. By the end of this, you’ll be clamping materials together with confidence for your next wood or metal project. These useful tools have been around for centuries for a reason. Ready to become a v clamp pro? Let’s dive in.

What Is a v Clamp?

A v clamp is a fastener used to securely join two pieces of material together. Sometimes called a bar clamp or C-clamp, it has a screw mechanism that allows you to adjust and apply pressure. V clamps come in a range of sizes depending on your needs.

To use a v clamp, first determine what size clamp you need for your project. A clamp that’s too small won’t provide enough pressure, while one too large will damage the material. Next, place the clamp over the adjoining pieces and hand-tighten the screw to hold them in place. Then use a wrench or clamp driver to tighten the screw and apply firm, even pressure. Be careful not to overtighten, which can also cause damage.

V clamps have many uses, including:

Woodworking and carpentry

  • Gluing boards together
  • Securing wood while drilling, sawing or sanding
  • Holding cabinets, frames and furniture together during assembly


  • Holding metal pieces together for welding, soldering or riveting
  • Securing sheet metal for cutting, drilling or shaping

Automotive applications

  • Holding hoses, pipes and wiring in place during installation or repair
  • Securing body panels when installing or removing

With proper installation and pressure, v clamps provide a strong temporary or permanent bond between two adjoining pieces of material. Be sure to remove clamps once glue, epoxy or other adhesives have fully cured to avoid indentation. V clamps—a simple but essential tool for any workshop or garage.

Installing a v Clamp on an Oil Catch Can

To install a v clamp on your oil catch cans, you’ll need a few basic tools and some patience. But don’t worry, if you follow these steps, you’ll have it secured in no time.

Gather your supplies

You’ll need:

  • Adjustable wrench or pliers
  • Screwdriver (Phillips head)
  • Your oil catch can kit which should include hoses, mounting bolts, washers and the v clamp

Locate a sturdy mounting point

Find a spot on your engine, frame or firewall that will securely hold the weight of a full catch can. Popular options include:

  • Valve cover: If there are unused bolt holes on top of your valve cover, this can work great. You may need longer bolts.
  • Frame rail: The frame rail running along the side of the engine bay is ideal. You’ll just need to drill holes for the mounting bolts.
  • Firewall: The firewall between the engine bay and cabin has solid metal to clamp to. Again, you’ll need to drill holes.

Install the mounting bolts

Thread the mounting bolts through the v clamp and into your pre-drilled holes or existing bolt holes. Slide washers over the bolts and tighten with your wrench until snug.

Attach the hoses

Connect your inlet hose to the bottom of the catch can and the other end to your valve cover vent or PCV valve. Connect the outlet hose from the top of the can to your intake. Double check that all connections are tight and hoses are secure.

With your v clamp installed and hoses properly connected, your oil catch can is ready to keep your engine bay pristine! Be sure to check all connections after your first drive to ensure nothing has come loose before hitting the road again.

Other Applications for v Clamps

V clamps have many useful applications beyond woodworking and metal fabrication. Their sturdy yet adjustable design makes them suitable for various tasks where you need to grip and secure objects.

Crafting and DIY Projects

For any hobby or DIY project, v clamps come in handy. Use them to hold pieces of wood, plastic or metal together as glue dries or while you work. They’re ideal for securing oddly-shaped items that are hard to clamp in a vise. V clamps can also hold a project steady on your workbench.

Automotive Work

If you do your own mechanical work, v clamps are a must-have tool. They can grip and support exhaust pipes, fuel lines, and other automotive components. V clamps provide an extra set of “hands” to hold parts in place as you bolt, weld or solder them. Be very careful using v clamps on finished vehicle surfaces to avoid scratches and dents.


Plumbers frequently rely on v clamps and c-clamps to secure pipes during installation or repair. The clamps allow you to temporarily join and support pipes at the proper angle before soldering or cementing them together permanently. V clamps can also clamp hoses, valves and other plumbing equipment in place.

Electrical Work

Electricians use v clamps to secure conduit, wiring and junction boxes when installing or servicing electrical systems. The clamps provide stability and support, allowing the electrician to connect wires and components with both hands. Be extremely cautious using any clamp on live electrical wires or equipment to avoid injury.

As you can see, v clamps have many practical uses for both professionals and hobbyists. Their simple yet robust design makes them suitable for gripping and bracing a wide range of items. With the proper safety precautions taken, v clamps can be an indispensable multi-purpose tool for any workshop or job site.


Now that you understand the basics of v clamps, you’re ready to put your new knowledge to work. Whether woodworking, metalworking or any other hands-on hobby, v clamps can make the job safer, easier and help you achieve better results. Don’t be intimidated by their industrial look – v clamps are very straightforward to use once you get the hang of it. Start with some simple practice projects to build up your confidence, then unleash your creativity. You’ll be clamping materials together in no time and wondering how you ever worked without these versatile tools. Keep this guide on hand for a quick refresher anytime you need it. Now get out there and start clamping! The possibilities are endless.
