How to Choose the Best Spreader Clamps
Material and Durability
Spreader clamps are often made from steel, aluminum, or heavy-duty plastic. Steel offers superior strength and longevity, making it ideal for demanding tasks. Aluminum is lighter and resistant to rust, while high-impact plastic can be suitable for lighter-duty applications where corrosion resistance is key. Consider the environment in which the clamp will be used, especially if it's exposed to moisture or corrosive substances.
Jaw Design and Capacity
The design of the clamp's jaws significantly impacts its functionality. Look for features like rubberized tips to prevent marring delicate surfaces, or serrated jaws for a more aggressive grip. The jaw opening capacity is also critical; ensure it can accommodate the thickness of the materials you typically work with. Some clamps offer adjustable jaws or specialized shapes for unique applications.
Frequently Asked Questions
What is the primary use of spreader clamps?
Spreader clamps are primarily used to hold materials together while adhesives cure or during assembly. They can also be used to create space between objects or to apply controlled pressure.
Are spreader clamps suitable for woodworking?
Yes, spreader clamps are very useful in woodworking for holding pieces of wood together during gluing and assembly. Ensure the clamp's jaw pads are soft enough not to damage the wood surface.
How do I choose the right size spreader clamp?
Consider the maximum thickness of the materials you need to clamp. Measure the widest gap you anticipate needing to secure and choose a clamp with a jaw opening capacity that exceeds this measurement.
Can spreader clamps be used for metalworking?
For metalworking, it's important to select robust spreader clamps, typically made of steel, with jaws designed to grip metal securely. Ensure the clamp has sufficient clamping force for the metal pieces you are joining.
