Frequently Asked Questions
What are the physical dimensions of this spring?
This spring has an outside diameter of 0.219 inches (5.56 mm), an inside diameter of 0.193 inches (4.90 mm), a free length of 0.310 inches (7.87 mm), and is wound from 0.013-inch (0.33 mm) stainless wire.
Are the ends squared and closed?
Yes, this spring features closed ends to provide stable, flat seating in recessed pockets or against flat surfaces.
Why buy individual springs here instead of large distributor packs?
Standard suppliers often impose high minimum order quantities for small hardware. Purchasing here gives you the exact count needed for a repair, prototype, or test fixture without holding unused inventory. Shipping is $8 flat rate across your order, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Small springs have a habit of disappearing across the shop floor during a teardown. Keeping a few clean spares on hand ensures a missing millimeter does not halt the entire project.
