Frequently Asked Questions
What is the end style on this spring?
This spring features closed ends, providing a flat seating profile for stability in spring pockets or over guide rods.
What material is used for the W87-CS spring?
It is manufactured from 302/304 stainless steel, offering standard corrosion resistance for industrial and laboratory environments.
Why buy individual Century Spring components here rather than a bulk pack?
You can purchase the exact piece count needed for a repair or prototype run without distributor minimum-order quantities. Shipping is $8 flat rate, free once the order passes $28, and orders leave the Idaho warehouse the same or next business day.
When a precision mechanism needs just a fraction of an ounce of force to return to zero, the right wire gauge makes all the difference. Drop it into your assembly and let smooth mechanical action take over.
