Frequently Asked Questions
What material is this spring wound from?
This spring is manufactured from stainless steel wire, providing corrosion resistance for mechanical assemblies.
Are the ends ground flat?
The ends are closed but not ground.
Why buy individual springs here rather than a bulk assortment?
You get the exact verified catalog spring you need for your repair or build without paying for an assorted box of off-spec sizes. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, free once the order passes $28, and orders leave our Idaho warehouse the same or next business day.
Sometimes a build stalls out for lack of one stiff, honest little spring that fits where nothing else will. Drop it in, feel that clean mechanical snap, and get the assembly back to work.
