Frequently Asked Questions
Are the ends of this spring squared and ground?
Yes. The AA-8CS features closed and ground ends, allowing it to sit flat and square against flat mounting faces without tilting under load.
What is the benefit of 302/304 stainless steel for this spring?
The 302/304 stainless steel construction provides corrosion resistance and consistent mechanical performance in humid, outdoor, or chemically mild operating environments.
Why purchase individual springs here instead of bulk factory assortments?
Buying individual pieces lets you obtain the exact physical dimensions and spring rate needed for a specific repair or prototype without purchasing hundreds of unused units. Every order ships from our Idaho warehouse for an $8 flat rate, qualifies for free shipping on orders over $28, and leaves our facility the same or next business day.
When the return mechanism on a bench project needs just the right push, having the exact wire rate and flat-ground ends makes all the difference between a sloppy action and a crisp snap.
