Clamp Buying Guide

In a workshop, clamps often have an important role as they hold objects in place steadily, and much better than human hands can do. Clamps are tools that apply inward pressure in order to secure or hold objects tightly together. Learn about the main features of clamps as well as the available types in order to find a suitable clamp for your task.


How Clamps Work

A clamp is a hand tool with opposite parts or sides that you adjust and bring closer together to compress or hold something. The capacity of the clamp depends on the size of piece that the clamp can hold when you extend the screw fully. Another feature of a clamp is the throat depth, the distance from the centre of the screw to the inner edge of the frame.


Clamp Uses

The most useful application of a clamp is probably securing adhesives. When gluing two pieces together you can use a clamp to keep them together, especially when the adhesive needs to dry for an extended period of time. In woodworking, you can also hold pieces of wood firmly on the workbench with a clamp when sanding or cutting. You can use clamps for a variety of worksite, household, and automotive tasks.


Clamp Types

There are many clamps available and they differ from each other in their features and uses. Some are specialised clamps suitable only for certain tasks. For instance, spring clamps are for odd shapes. Thus, you should consider a clamp purchase thoroughly in order to buy the right one.
