SPEC conical springs are cone shaped compression springs
designed to provide a near constant spring rate and a solid height
lower than a normal spring. Each sping features a variable pitch to
achieve the constant spring rate and colis which nest during
deflection to provide a solid height approximately equal to the two
All springs are manufactured from stainless steel for use in a
multitude of environments.
Stainless steel type 302 per ASTM, A313 or AMS 5688
spring temper. (chemical and physical only)
Stainless steel springs are not recommended for applications where
the temperature exceeds 500 degrees Fahrenheit (260 C)
Certificate of chemical analyses available at additional
Standard finish is that of the normal wire.

Squared ends not ground.
The spring rate is linear due to the variable
Springs are designed to permit active colis to nest
within each other. This provides a solid height of approximately
two wire diameters.
Due to coils nesting, the solid height is approximately
equal to two wire diameters.
