HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 1250D 06 is a heavy-duty die compression spring from the HEFTY™ Die Spring series, specifically engineered for demanding industrial applications requiring durabiliy and substantial load capacity. This spring features an 1.195-inch outside diameter (30.35 mm) with a 1.25-inch hole diameter (31.75 mm) and extends to a free length of 4.5 inch (114.3 mm), making it ideal for stamping and die applications. Made from Oil Tempered Chrome Silicon with a 0.262-inch wire diameter (6.65 mm), the spring delivers a spring rate of 784 lb/inch (137.304 N/mm) through its 10.64 active coils out of 12.64 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 3.32 inch (84.33 mm) while supporting a maximum load of 925.1 lb (4115.05 N) at full compression. The spring has Squared and Ground ends and a Orange Powder Coat finish for optimal die spring performance.
