2 Pack Black Compression Springs, 1.7" OD x 1.25" ID x 3.9" Free Length, 1/4" (218 Gauge) Wire Diameter, 163 lbs/in Spring Rate Heavy Duty Coil Springs
Precise Dimensional Specifications - Features 1.7" outer diameter (OD), 1.25" inner diameter (ID), 3.9" nominal free length, and 1/4" (218 gauge) solid coil wire diameter, manufactured to consistent dimensional tolerances for reliable fitment
Black Oxide Surface Finish - Made of high-grade spring steel with a uniform black oxide coating, delivering a smooth, corrosion-resistant surface that maintains structural integrity through repeated compression cycles
163 lbs/inch Stable Spring Rate - Engineered with a consistent 163 pounds per inch spring rate, providing predictable linear compression force and steady load-bearing performance across the full working stroke
Closed End Coil Construction - Adopts closed and ground end coils for even load distribution, stable placement, and reduced buckling during compression, compatible with standard spring mounting configurations
Broad Mechanical Application Compatibility - Suitable for industrial equipment, machinery repair, automotive component replacement, DIY fabrication projects, and other scenarios requiring matched compression spring specifications
