Spring Measurements and Specifications

Spring measurements and spring specifications for

compression, extension and torsion springs are below.

Follow the guidelines below for the type of spring you

have to determine your springs measurements and spring specifications.

How to measure Compression Springs, Coil Springs and
Helical Springs (These spring types are all the same)

To Measure your coil springs correctly
See diagram to the right for explanation.  ------------------------------->


You will need to know the four (4) spring specifications below:

1. Wire diameter
2. Outer diameter
3. Free Length (length of spring) 
4. Number of total coils

Also please choose the Spring End Type you desire:                                       




Closed and Squared Ends 
The last coil is closed touching the previous coil 
closed and squared ends is the most economical of

all end types and works well for standing up normal size

springs. Closed and squared ends do NOT work well if

you have a spring with a small outer diameter you should

choose closed and ground ends so it will stand up vertically

straight.

Closed and Ground Ends
The last coil is closed and ground flat touching with the
previous coil. Closed and ground ends help the spring stand
up vertically straight. This type of end lets your spring stand
up straight and gives an even surface of contact to the spring
base. A good choice for precision springs though a bit more
costly than closed and squared ends because additional labor
needs to be performed to grind the ends of the spring flat.

Double Closed Ends
The last two coils on each end are closed to help stabilize
the top and bottom of the spring. Double closed ends aids
your springs footing especially when you have a large outer
diameter coupled with a fine or smaller diameter wire when
compressing or traveling to stacked height where all the

coils are touching. Double closed ends help your spring ends

from sliding over or slipping under the previous coil, it

keeps the coils stacked up on top of each other correctly.

This is an great economical choice to prevent buckling

and stabilizes your spring .

Open Ends
The ends of the spring are open and have space or pitch

in-between them. This is a good option if you need more force

out of your spring but don't have the room for it. An

open ended spring makes all of your coils active thus getting

the all the force out it. This kind of spring end requires that

you place it in hole or on a shaft to make it work. Their is

usually no extra cost for this type of end thus making it

an economical choice.

How to measure Extension Springs and Tension Springs

To Measure your Extension Springs Correctly

See diagram to the right for explanation.  ---------------------------------->
 

You will need to know the following extension spring measurements:



1. Wire Diameter
2. Outer Diameter   
3. Length inside Hook
4. Body Length
5. Choose your hook type below:





Choose from the different hook types below:






Machine Hook
A good standard hook choice for commercial springs.
This hook is made from the end coils on the spring by
bending it out to create this hook. Machine hooks
should not be stretched over their limit to avoid
breakage.    

Cross Over Center Hook
A great standard hook choice for precision
springs and commercial springs. This type of hook
is made from the end coils of the spring but is bent
straight down the center of the spring, it then loops
around to create the round hook. This is a more
stable hook than the machine hook for the same price.


Side Hooks
The most economical of all hooks is the side hook.
This hook is made from the end coils. It is bent outwards
from the side of the spring to create the side hooks. This
is a good hook for an commercial or everyday spring
which doesn't have to be precise.


No Hooks
This type of no hook spring is very useful
when inserting a bolt down through the inner diameter
so to anchor the spring ends. The ends of the spring act
as threading onto the threads of the bolt thus securing the
ends. This type of fastening or connecting has tremendous
benefits especially when dealing with broken hooks that
cause a user to purchase extension springs repeatedly.
Fastening the spring to a bolt or a thread offers superior
strength versus any other hook type and is the most
economical to manufacture.

Extended Hooks
This is a good hook that is used when having to get around
an object to engage the hook too. It offers the user a way
to get the hooks fastened by extending the length of the
hook to reach into the area where one will attached the
hook. Extended hooks can be made with larger or smaller
diameters than the extension springs normal outer body
diameter. This type of hook is the most costly but can really
make the difference when installing an extension spring
where no other hook will work.

How to measure Torsion Springs:

To Measure your Torsion Springs Correctly
you need to know the following torsion spring dimensions:
See diagram to the right for explanation. ----------------------------------->


1. Choose your direction of wind: Left hand or right hand
Please see diagram to the right to determine if your

spring is Left hand or Right hand.
2. Wire diameter
3. Outer diameter
4. Number of total coils
5. Length of leg 1       
6. Length of leg 2
If your spring has any bends or shapes on the legs please let us know.
