The Best Clamps

Clamps Reviews

Our Top Pick is the Denali 14-Piece Spring Clamp

Clamps (more specifically, spring clamps) are very common carpentry tools used to hold two or more items together, such as: wires, tools chords, cables, and work materials. They work by creating a controlled and powerful force in its opening by compressing materials together and holding them firmly and securely in place. The reason clamps are able to hold items together with such a great amount of force is because they are equipped with tightly wound coils located in their centers that drive force into both sides of the device causing a pinching action into a centralized space, then “clamping” your items together. The force can then be release or lifted when applying pressure, or squeezing the opposite ends, which will release the tight end containing your materials.

Spring clamps are inexpensive tools that provide many uses, making them essential to virtually anyone’s tool arsenal. Spring clamps, as well as other types of clamps are found in a wide variety of sizes to better accommodate a variety of needs.  Some examples of tasks clamps, or spring clamps can perform are, holding wires in place, holding two materials together while glue, or other adhesives dry and form together.

Who Should Buy This

Given the versatility and affordability of clamps and spring clamps, they are very beneficial to a large audience of people. Some people who will enjoy the use of spring clamps include auto mechanics, those who participate in DIY projects, homeowners, carpenters, furniture makers, quilters, craftsmen, wood workers, construction workers, welders, engineers, or anyone who works with their hands. Durable clamps are both strong enough to hold objects together and yet gentle enough not to scratch or damage the items.

What Makes a Good Clamp?

When considering clamps there are several qualities and features that compose the best overall products, the first being size variation. Clamps are multi-purpose tools with many available functions, and in most cases are purchased in multiple sizes or kits for this very reason. These kits provide various sized clamps ranging from petite to very large options allowing you to expand their uses even further. The larger clamps are more suited to mechanical needs such as jump starting a vehicles battery, or holding together two larger pieces of work materials. Smaller clamps hold small wires, thin materials, and smaller items together, which would otherwise become loose with larger clamps. Finding a kit with a wide variety of clamp sizes will add to the versatility of your clamps.

ClampsThe next quality that makes up the best clamps is a heavy duty spring. The spring located in the center of your clamp is what’s holding your clamps altogether and giving them the strength they need to provide proper support to materials. A spring with too much pressure has the potential to damage materials by placing too much stress and force on them. A weak spring can result in the objects not being secure enough potentially creating a hazard.

Another feature to look for is the durability of the materials the clamps are constructed with. This along with the strength of the spring will determine how long the clamps will last. If the clamps are not made from strong materials, even with a strong spring they will not be able to hold items together adequately.  Clamps need a tough exterior to be compatible with the force they require to successfully do the jobs they are designed for. Clamps are often made of heavy plastic or metal and should come with a comfortable grip that allows you to open and secure the clamp with ease.

The last feature you will want to look for in the best clamps will be a soft jaw material. The jaw of the clamp is the ticket to success as the jaw is the end is what is attached to your working materials. The jaw piece must be strong enough to hold your materials and come with a non-slip grip to firmly and secure hold the materials. However, if your jaw is not crafted with a soft material, the jaw can puncture or damage the work materials they are holding.
