The spring features a 0.188 inch outside diameter, 0.750 inch free length, and 0.016 inch wire diameter with closed ends.
Why buy this individual spring instead of a large bulk assortment?
For bench repairs, prototypes, or single-unit replacements, buying the exact spring spec needed saves you from stocking a bulk box of unused hardware. Standard shipping is an $8 flat rate, free once your order passes $28, and orders ship from our Idaho warehouse the same or next business day.
Small mechanical springs are the quiet backbone of every positive latch and smooth return. Drop this into place and get your mechanism working with exact tension.
