NiTi Adjustable Force Preformed 15mm Open Coil Springs, .010 x .030, 100g, Pack of 10

These nickel-titanium open coil springs are preformed to 15mm and provide a range of closing forces based on deflection, with the selected force not fading like stainless steel. Finished ends facilitate easy placement, and compressing the coil to 3mm delivers an ideal 75g force for space maintenance. Approximate force is the unloading force at 5mm deflection from free length.
