Frequently Asked Questions
Are the ends of this spring ground flat?
No. The spring ends are closed but not ground.
Why buy individual springs here instead of a full industrial pack?
Most repairs and prototype builds only require the exact spring you need rather than a large minimum-order factory pack. You get verified Century Spring hardware counted out per piece without excess shelf inventory. Standard shipping is an $8 flat rate, orders over $28 ship free, and everything leaves our Idaho warehouse the same or next business day.
Small mechanisms grind to a halt when tiny springs lose their temper or vanish from the bench. Keep the exact stainless replacement ready so the fix takes minutes.
