What Are Clamps?
Clamps are tools used to clamp, fix, or hold objects together. They are available in hand clamps that lock in place for sustained hold and screw clamps that secure objects by tightening a screw. These tools provide stabilization that’s challenging to achieve manually, making them essential for heavy-duty tasks. Clamps vary in size, from small, one-hand operable clamps to large ones requiring both hands.
Choosing the right clamp depends on the location and purpose of use.
How to Use Clamps
Clamps differ in operation based on their type:
- Hand Clamps
Operate by gripping the handle and using the mouth to clamp the object. The clamp moves to close but not to open, ensuring a secure hold. To release, lift the release lever to unlock and open the mouth. - Screw Clamps
Feature C-shaped jaws, with one side fixed and the other adjustable via a screw. Position the fixed part against the object and tighten the screw to clamp. The hold remains until the screw is loosened.
How to Choose a Clamp
Selection depends on the task at hand:
- Hand Clamps
Advantageous for convenience; grip and hold the object, release by lifting the lever. Ideal for light clamping and hands-free operations, but isn’t as strong as a screw clamp. - Screw Clamps
Offers high holding power through screw force, significantly stronger than handheld models. Requires screw adjustment for release, which can be complex for larger sizes and might need teamwork. Best for tasks needing a strong, stable hold, like cutting or welding operations.
