This spring features a 4.5-mm outside diameter (0.177 inch) with 3.23-mm loop inside diameter (0.127 inch) and extends from a free length of 12.09 mm (0.476 inch) to a maximum extended length of 17.75 mm (0.699 inch). Made from Music Wire with a 0.64-mm wire diameter (0.025 inch), the spring delivers a spring rate of 2.771 N/mm (15.82 lb/inch) through its 10 total coils with an initial tension of 2.611 N (0.587 lb) for predictable extension behavior. The spring supports a maximum load of 18.282 N (4.11 lb) at full extension with a body length of 6.99 mm (0.275 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.
