The hoses in the cooling system in your vehicles are connected and sealed with hose clamps. Spring and screw are two of the most common hose clamp types. If you need to change the hose clamps, you might get confused about which one is better. When deciding between spring hose clamps vs. screw hose clamps, experts prefer spring.
The major difference between a spring and a screw hose clamp is the amount of tension or pressure they put on the hose. Spring hose clamps put constant and firm tension. Screw clamp hoses are tightened with screws, and the inner diameter remains the same. In consequence, pressure is inconsistent on the hoses.
Is it enough to decide which one to use in your vehicle? Obviously not. There are some other differences that will help you to understand which one is better and why. Stay tuned till the end to know everything about spring and screw hose clamps and their differences.
Hose Clamps: The Basics
The main purpose of using hose clamps is to prevent leakage in the cooling system. Regardless of what type of vehicle you use, there should be multiple hose clamps. They come in various types. But most people use either spring hose clamps or screw hose clamps.

What is a Spring Hose Clamp?
Spring hose clamps, also known as constant tension hose clamps, are made of spring steel. They are cut in such a way that the connector at one end has an extension in the center, while the other end has extensions on each side. The design can be a little different, but the connector will always act as a spring.
If you ask how to use spring hose clamps, the answer is simple. First, press the tabs to enlarge the clamp. Then place the clamp on the hose and release the tabs. The spring hose clamp will create suitable tension on the hose.
What I like:
- The spring component helps to keep the pressure constant.
- It continues to put pressure as long as the hose is okay.
- It stays in good condition for a long period.
What I don’t like:
- It can not be used to create high pressure.

What is a Screw Hose Clamp?
Screw hose clamps, also known as worm gear clamps, are ring-shaped metal clamps that use screws as connectors. You can change the diameter as you want by turning the screw. The diameter will remain fixed as long as the clamp is in good condition or unless you change it.
But how to use a screw hose clamp? First, place it around the hose you want to seal. And then start tightening the screw to secure the hose. Do not try to overtighten as that can damage the hose or the screw.
What I like:
- The diameter remains the same, which can be good in certain situations.
- You can fix or change the diameter as you want.
What I don’t like:
- The screw can get loose over time.
- The fixed diameter of screw hose clamps can cut through and damage the hose.

spring hose clamps vs screw: Key Differences
Spring and screw hose clamps are two completely different types of clamps. Though the purpose is similar, their distinguishable features make one better than the other in certain situations.
Some of the common differences between spring hose clamps and screw hose clamps are:
The amount of pressure they use is a major difference that separates these two clamps. A spring hose clamp uses spring material; therefore, it can stretch or shrink with the hose. So, it keeps putting even pressure on whether the hose is dry out or enlarged.
In contrast, the diameter of a screw is fixed. So, when the hose is dried out, the pressure is low, and when the hose is enlarged, the pressure is strong.
As spring material can stretch or shrink when necessary, spring hose clamps are quite flexible with hoses. But screw hose clamps can not do that. As a result, when the hose is enlarged, screw hose clamps can cut into the hose pipe and damage it.
The design of the two clamps is also different. Another reason why screw hose clamps can cut through the rubber hose pipe is their sharp edges. Spring hose clamps designs do not have such sharp edges and are safer to use.
Both of the clamps have pretty good durability. They can serve you the lifetime of your car. However, in certain situations, the screw of the worm gear hose clamps can get loose.
Then it will make the hose insecure, and you may need to change the clamps. Spring hose clamps do not have such problems.
You can adjust the diameter of screw hose clamps within a certain range. But you do not get that benefit with spring hose clamps. So, when you need clamps with a specific diameter, screws are an obvious choice.
Spring hose clamps are compatible with both small and large diameters of hoses. Screw hose clamps are mainly used in hoses with a larger diameter, usually ½ inch and higher.

Which One Should You Buy?
After knowing the differences, you can easily decide which one you should buy. However, our recommendation would be to go for spring hose clamps considering the benefits they offer over screw hose clamps. You also can go for the screws if you need the benefit of adjusting the diameter.
