Frequently asked questions
What is the difference between a bar clamp and a pipe clamp?
A bar clamp has a fixed metal or fiberglass bar with a sliding head, while a pipe clamp uses a standard pipe as the bar, allowing you to choose any length. Pipe clamps are generally stronger and can span longer distances, but require purchasing pipe separately. Bar clamps are more convenient and self-contained.
How much clamping force do I need?
For light woodworking and crafts, 50 to 100 pounds per clamp is often enough. For cabinet making or furniture assembly, 150 to 300 pounds provides a secure hold. Heavy duty tasks like laminating countertops may need more force. Check the product specifications for the maximum force.
Can I use quick-grip clamps for one-handed operation?
Yes, most quick-grip clamps are designed for one-handed use. You squeeze the handle to tighten and press a trigger to release. This is a major advantage when you need to hold a workpiece while adjusting another, making them popular among DIYers.
Are mini clamps big enough for most projects?
Mini clamps typically have an opening of 6 inches or less. They are great for small repairs, model making, and edge gluing. For larger panels or frames, you will need longer clamps such as 12 or 24 inches. Many bulk packs include a mix to cover various needs.
What is a shim used for?
A shim is a thin wedge used to fill small gaps or make fine adjustments to level or align objects. In construction, they are used to plumb doors and windows or to level cabinets. Brass shims are durable and resist corrosion, making them suitable for many applications.
How many clamps should I buy?
For small projects, a set of four may suffice. For larger tasks like gluing a tabletop, you might need six or more. Buying a bulk pack of six is a good starting point for most enthusiasts. You can always supplement with additional clamps later.
Are pipe clamp fittings compatible with any pipe?
Pipe clamp fittings are designed for specific pipe diameters, such as 1/2-inch or 3/4-inch. They require threaded pipe of that size. Standard black or galvanized pipe works well. Ensure the pipe has threads on both ends or use a coupling to connect sections.
Do these clamps come with a warranty?
Most reputable brands offer a limited lifetime warranty against defects. Check the product listing for warranty information. Some manufacturers provide a satisfaction guarantee. It is always wise to inspect the clamps upon arrival for any issues.
Can I use bar clamps for metalworking?
Some bar clamps are suitable for metalworking if they have sufficient clamping force and a design that resists sparks and heat. However, woodworking clamps may not withstand heavy loads. For metalworking, consider clamps with higher force ratings and all-steel construction.
What is the best way to store bulk clamps?
Store clamps in a dry place to prevent rust. Some sets come with a storage rack or case. If not, you can hang them on a pegboard or place them in a toolbox. Keeping them organized saves time when you need a specific size.
The verdict
For most users, the IRWIN QUICK-GRIP Mini Bar Clamp 6-Pack is the best all-around choice, offering reliability and ease of use at a reasonable price. If you frequently work on large projects, invest in the Bessey Clutch Style Bar Clamp 4-Pack for its superior strength and reach. Budget-conscious buyers can start with the Jorgensen E-Z Hold set, but remember that quality and force are lower. Choose the pack that aligns with your typical project size and frequency.
