Frequently Asked Questions
What is the material composition of this spring?
This spring is manufactured from 302/304 stainless steel, offering high tensile strength and corrosion resistance for industrial, marine, or general workshop environments.
Are the ends of the spring squared and ground?
Yes. The ends are closed and ground flat to ensure even load distribution and square alignment against mating surfaces.
Why buy individual Century Spring pieces instead of bulk factory packs?
Ordering individual pieces lets you source the exact count needed for maintenance, prototyping, or small-batch builds without paying for full minimum-quantity packs. Orders ship for an $8 flat rate, or free once your order reaches $28, leaving our Idaho warehouse the same or next business day.
Nothing fixes a sticky mechanism or finishes a custom build quite like dropping in the exact spring rate on the first try.
